Contact Lenses

Multifocal Contact Lenses For People Over 40

If your 40th birthday has come and gone, you may have started to notice some changes in your vision. You might find yourself holding written material further away from your face in order to clearly read the fine print, or have a harder time adjusting your focus from distant objects to near ones.

The inability to see things clearly at various distances can be frustrating.

Fortunately, this problem can be solved by wearing multifocal contact lenses. Below, we’ll explain the cause and symptoms of presbyopia, along with the many benefits of wearing multifocal contact lenses.

What Is Presbyopia?

Presbyopia is the natural and gradual loss of your eyes’ ability to focus on near objects.

The crystalline lens in your eye focuses light onto the retina, and it adapts its shape depending on what you focus on. From infancy until your late 30s or early 40s, the lens is usually clear, thin and very flexible, allowing fast adjustments for sharp vision at all distances.

From age 40-50 the lens becomes considerably thicker and much less flexible. This makes it harder for the lens to change shape and to accurately refract light when focusing on near objects.

This farsightedness can be easily corrected with reading glasses, bifocal or multifocal glasses, monovision contact lenses, as well as multifocal contact lenses.

Multifocal Contact Lenses for Presbyopia

Multifocal contact lenses contain multiple lens powers to provide vision correction for different visual zones so you can clearly see objects that are in the distance, nearby and everything in between.

Certain multifocal contact lenses have 2 lens powers (bifocals), for near and distance vision, and others have a more gradual power change, similar to progressive lenses. These contact lenses can be made using soft materials or rigid gas-permeable materials, and are available as daytime or extended night-wear lenses.

Note that multifocal contact lenses are not perfect for all situations and some patients may need to try several brands or designs before finding one that works well for them. To spare you the confusion, your optometrist will guide you towards the ones best suited to your eyes and lifestyle needs.

Q&A:

#1: Are there any “cons” related to wearing multifocal contact lenses?

Many multifocal contact lenses use a “simultaneous vision” design that allows seeing far and near simultaneously through concentric zones. Some people have problems adapting to this, noticing hazy vision and less contrast than single vision lenses. You can ask your optometrist to be fit with multifocal lenses and get a test run” or trial period.

#2: When does presbyopia stabilize?

Most people will start to develop age-related vision changes starting in their early to mid-40s. At around 60 years of age, your eyesight will begin to stabilize and you’ll notice less of a need to update your lens prescription. Nonetheless, yearly comprehensive eye exams at this age are more important than ever, as they enable your eye doctor to detect potential eye conditions and diseases early on.

Coronavirus and Your Eyes – What You Should Know

As coronavirus (COVID-19) spreads around the world, health professionals are demanding that people limit their personal risk of contracting the virus by thoroughly washing their hands, practicing social distancing, and not touching their nose, mouth, or eyes. In fact, it may surprise you to learn that the eyes play an important role in spreading COVID-19.

Coronavirus is transmitted from person to person through droplets that an infected person sneezes or coughs out. These droplets can easily enter your body through the mucous membranes on the face, such as your nose, mouth, and yes — your eyes.

But First, What Is Coronavirus?

Coronavirus, also known as COVID-19, causes mild to severe respiratory illness associated with fever, coughing, and shortness of breath. Symptoms typically appear within 2 weeks of exposure. Those with acute cases of the virus can develop pneumonia and other life-threatening complications.

Here’s what you should know:

Guard Your Eyes Against COVID-19

Avoid rubbing your eyes. Although we all engage in this very normal habit, try to fight the urge to touch your eyes. If you absolutely must, first wash your hands with soap and water for at least 20 seconds.
Tears carry the virus. Touching tears or a surface where tears have fallen can spread coronavirus. Make sure to wash your hands after touching your eyes and throughout the day as well.
Disinfect surfaces. You can catch COVID-19 by touching an object or surface that has the virus on it, such as a door knob, and then touching your eyes.

Coronavirus and Pink Eye

Pink eye, or conjunctivitis, refers to an inflammation of the membrane covering the front of the eyeball. Conjunctivitis is characterized by red, watery, and itchy eyes. Viral conjunctivitis is highly contagious and can be spread by coughing and sneezing, too.

According to a recent study in China, viral conjunctivitis may be a symptom of COVID-19. The study found conjunctival congestion in 9 of the 1,099 patients (0.8%) who were confirmed to have coronavirus.

If you suspect you have pink eye, call your eye doctor in North Miami Beach right away. Given the current coronavirus crisis, we ask patients to call prior to presenting themselves at the office of Dr. Ben-Nissan, as it will allow the staff to assess your condition and adequately prepare for your visit.

Contact Lenses or Eyeglasses?

Many people who wear contact lenses are thinking about switching to eyeglasses for the time being to lower the threat of being infected with coronavirus.

Wearing glasses may provide an extra layer of protection if someone coughs on you; hopefully that infected droplet will hit the lens and not your eye. However, one must still be cautious, as the virus can reach the eyes from the exposed sides, tops and bottoms around your frames. Unlike specialized safety goggles, glasses are not considered a safe way to prevent coronavirus.

Contact Lenses and COVID-19

If you wear contacts, make sure to properly wash your hands prior to removing or inserting them. Consider ordering a 3 to 6 month supply of contact lenses and solution; some opticals provide home delivery of contact lenses and solutions. At this stage there is no recommendation to wear daily lenses over monthlies.

Don’t switch your contact lens brand or solution, unless approved by your optometrist or optician.

Regularly Disinfect Glasses

Some viruses such as coronavirus, can remain on hard surfaces from several hours to days. This can then be transmitted to the wearer’s fingers and face. People who wear reading glasses for presbyopia should be even more careful, because they usually need to handle their glasses more often throughout the day, and older individuals tend to be more vulnerable to COVID-19 complications. Gently wash the lenses and frames with warm water and soap, and dry your eyeglasses using a microfiber cloth.

Stock up on Eye Medicine

It’s a good idea to stock up on important medications, including eye meds, in order to get by in case you need to be quarantined or if supplies run short. This may not be possible for everyone due to insurance limitations. If you cannot stock up, make sure to request a refill as soon as you’re due and never wait until the last minute to contact your pharmacy.

It is important that you continue to follow your doctor’s instructions for all medications.

Digital Devices and Eyestrain

At times like this, people tend to use digital devices more than usual. Take note of tiredness, sore eyes, blurry vision, double vision or headaches, which are symptoms of computer vision syndrome if they are exacerbated by extensive use of digital devices, and might indicate a need for a new prescription in the near future. This usually isn’t urgent, but if you’re unsure, you can call our eye doctor’s office.

Children and Digital Devices

During this time your children may end up watching TV and using computers, tablets and smartphones more frequently and for more extended periods too. Computer vision syndrome, mentioned above, can affect children as well. We recommend limiting screen time to a maximum of 2 hours per day for children, though it’s understandably difficult to control under the circumstances.

Try to get your child to take a 10 to 15 minute break every hour, and stop all screen time for at least 60 minutes before sleep.

Children and Outdoor Play

Please follow local guidelines and instructions regarding outdoor activities for your children. If possible, it’s actually good for visual development to spend 1-2 hours a day outside.

From all of us at BenNissan Eyes in North Miami Beach, we wish you good health and please stay safe.

Visiting Your Optometrist During COVID-19

Is your eye doctor’s appointment coming up? Are you worried about going to the eye clinic during the new coronavirus (COVID-19) pandemic? Rest assured, keeping our patients and staff are safe is our top priority.

We anticipate that this outbreak will continue for a while, and do not want our patients to neglect their eye care needs during this critical time. Our optometric clinic is prudent and has adopted specific measures to protect our patients and staff from potential exposure to COVID-19 during this time of uncertainty.

That said, guidelines for slowing the spread of this epidemic are rapidly changing. Please pay close to attention to local regulatory changes to get the most up-to-date information on whether practices can still remain open/ accept non-emergency cases.

Here Are the Precautions Our Eye Clinic Is Taking to Limit COVID-19:

We employ a strict office policy that mandates that all eye doctors, opticians, office staff, and patients not enter if they are feeling unwell or have a fever, cough, sore throat, runny nose, shortness of breath, or have been exposed to a known case of COVID-19 or traveled outside of the country within the last 14 days.

The staff may ask you to wait outside rather than in the waiting area in order to protect yourself and others from any circulating germs. Furthermore, we are trying to schedule our appointments in such a way that our waiting room remains as empty as possible.

During your eye exam:

The eye doctor may use a special plastic barrier called a slit-lamp breath shield to block the exchange of breath between patient and doctor.
The optometrist may wear a mask with a plastic shield over the eyes.
The practitioner will wait for your slit-lamp eye exam to be over before speaking with you or answering any questions you may have.
We sanitize all equipment and patient contact surfaces after every use and at the end of the day.
We sanitize all surfaces and equipment (front desk counters, telephones, pens, door handles, waiting room chairs) with antibacterial wipes.
All staff members wash their hands after contact with each patient and throughout the day.
Our office is equipped with several sanitizing stations.
We request that patients sanitize their hands prior to and after trying on frames. We also make sure to clean frames that have come into contact with patients with soap and hot water.
If we don’t shake hands with our patients during this time, please don’t take it personally.

Please call BenNissan Eyes at 772-248-4321 with any questions or concerns you may have. If you feel it’s best for you or a member of your family to reschedule your appointment, we encourage you to do so.

To stay abreast of the coronavirus pandemic, please visit the following official health organizations:

Thank you and stay safe!

Can Contact Lenses Give Me 20/20 Vision?

Before our eye doctor answers the question about whether or not contacts can help you achieve 20/20 vision, let’s discuss what those numbers mean. Everyone talks about 20/20 vision all the time, but what is it exactly? Our optometrist at your nearby eye care center in North Miami Beach can answer any questions you may have.

What’s the meaning of 20/20?

In general, “normal eyesight” is referred to as 20/20 vision. These numbers describe what you should see when standing 20 feet away from an eye chart. Accordingly, if you are diagnosed with 20/40 vision, it means that when you stand 20 feet away from the same eye chart, you can only see the details that a person with normal eyesight sees at 40 feet. That makes your vision weaker than average. In contrast, if you have 20/10 vision, it means that if you stand 20 feet away, you can see details that most people only see at 10 feet – which is better than the normal standards for vision.

How sharp will I be able to see with contact lenses?

At our North Miami Beach eye clinic, we aim to fit you with contact lenses that give 20/20 vision. Our experienced, skilled optometrist will check your visual acuity with the help of a basic Snellen testing chart and advanced diagnostics. We’ll figure out your precise vision prescription for contact lenses, giving you 20/20 vision or close to it. Our eye doctor is dedicated to making sure you enjoy the sharpest vision possible for your lifestyle needs!

Is it possible to see better than 20/20?

Yes, it is certainly possible. But the accepted gold standard is to correct human vision conditions with lens powers that bring your eyesight to the average norm of 20/20. On the other hand, if you are an eagle (and our eye doctor welcomes all eagles to visit us at BenNissan Eyes when flying through North Miami Beach), we can treat you with prescription contact lenses to restore the standard 20/5 vision that gives eagles a fine bird’s eye view of the world!)

Contact lenses vs. eyeglasses – do they give the same vision quality?

As far as vision quality goes, the primary advantage of contact lenses is that they offer more natural vision. Because they sit directly on your eye, they bend light in a way that’s closer to the requirements of your vision prescription. In addition:

Contacts also move along with your eyes, and no bulky frames block you from having clear peripheral vision – without needing to turn your head. (This is a big plus for people who play sports!)
Contact lenses don’t fog up when it’s cold outside or get wet when it’s rainy, so you have sharp vision in all weather conditions.
If you have astigmatism, our North Miami Beach eye doctor may recommend rigid gas permeable contact lenses, because they can give more acute vision than soft lenses and eyeglasses.

What’s better for me – contacts or glasses?

If your eyes are generally healthy, the choice between glasses and contact lenses is yours to make. Like everything, there are pros and cons to each type of vision correction. How should you make this decision? It mainly comes down to lifestyle and personal preferences. At our North Miami Beach eye care center, we’ll discuss your daily activities with you to help determine whether eyeglasses or contact lenses are most suitable.

Looking for 20/20 vision with contact lenses? Visit our North Miami Beach eye doctor near you!

To see the best that you can see, book an eye exam at BenNissan Eyes. Our optometrist will evaluate your vision and eye health to make sure you are a good candidate for contact lenses.

Why You Shouldn’t Rub Your Eyes

Do Your Eyeglasses Fit Right?

Why Are Dilated Eye Exams So Important?

Here’s Why Hydrogen Peroxide is an Excellent Contact Lens Solution

Once you and your doctor have decided on the type of contact lenses you’ll need, it’s time to choose the most suitable contact lens solution for your eyes and contacts.

There exist 2 different types of solution for contact lenses: Multipurpose and Hydrogen Peroxide-based. While both remove debris and build-up, and disinfect lenses, only hydrogen peroxide is capable of penetrating the microbial biofilms for a deeper clean. As an added benefit, hydrogen peroxide does not contain preservatives — which can be particularly beneficial for those with allergies or eye sensitivities.

Multipurpose Solution

Multipurpose solutions are straightforward and easy to use; only one solution is needed to rinse, clean, disinfect and store your contacts (as seen in the image). Their convenience and low cost make them a popular choice.

Hydrogen Peroxide Solution

Hydrogen peroxide solutions, such as Clear Care® by Alcon or Refine One Step™ by CooperVision, contain no preservatives or allergens. This solution thoroughly breaks up the proteins and removes deposits on the lenses during the disinfection process, which can be beneficial for people who tend to accumulate large amounts of build-up on their lenses. Moreover, hydrogen peroxide is more effective at battling acanthamoeba keratitis (an eye infection that may lead to blindness) than all other types of contact lens solutions.

Since hydrogen peroxide is a chemical that causes stinging and burning when it touches the eye, after the contacts have been disinfected the solution must be neutralized to be healthy for your eyes. Included with every solution bottle is an upright contact lens case containing a platinum-coated disk that chemically reacts with hydrogen peroxide to decompose it into a safe, non-irritating, sterile saline solution. This chemical reaction produces bubbles inside the case as it undergoes the transformative process over a period of several hours. Since the neutralizing disk loses its effectiveness over time, it is critical to regularly replace it.

If your eyes do make contact with hydrogen peroxide, make sure to immediately flush it out with sterile saline. If saline is not available, wash your eyes with water or artificial tear drops and make sure to see Dr. Ben-Nissan as soon as possible. Though painful, it doesn’t cause permanent eye or vision damage.

How does it work?

To clean your lenses, place them in the designated case that is freshly filled with the hydrogen peroxide solution and soak them for 6-8 hours. This can be a one-step or two-step process, depending on the product. The one-step products contain a built-in neutralizer in the contact lens case, while the two-step products require you to add a neutralizing tablet to the solution after cleaning.

Make sure not to reuse or top off hydrogen peroxide solution after it has been neutralized, as it will have lost its disinfecting power.

Be sure to dry your case thoroughly between uses and to replace your case every 2-3 months to prevent infection.

It is important to note that hydrogen peroxide solutions will change into unpreserved saline. Therefore, if contact lenses are stored for extensive periods of time (e.g. more than a couple days), it is safer to consider multiple-purpose solutions for long term.

Hydrogen peroxide-based solutions are known for their exceptional disinfecting ability. At BenNissan Eyes, in North Miami Beach, our patients are extremely satisfied with the cleanliness and comfort they experience when using hydrogen peroxide-based solutions for their contact lenses. Speak with Dr. Ben-Nissan to find out whether this solution is right for you.

12 Tips for Optimal Eye Health

Expert Eye Care| Optometrist in North Miami Beach | BenNissan Eyes

Good Eye Care Habits & Hygiene

By practicing good eye care habits and hygiene, you can prevent many vision problems from occurring. Eye problems and the risks associated with vision loss only grow as you age. By neglecting eye care, you place yourself at a higher risk of suffering from cataracts, macular degeneration, glaucoma, diabetic retinopathy, and low vision.

So make sure you maintain great eye health by following these 12 tips for optimal eye health.

1. Avoid rubbing your eyes

Itchy eyes can be a hallmark symptom of allergies, and though rubbing may bring temporary relief, it ultimately increases swelling and worsens the itch. If you wear contact lenses, rubbing your eyes can also dislodge or even break a lens, causing the lens to get lost or scratch the cornea. Plus, eye rubbing can lead to eye infections, since our hands are typically covered with a host of germs.

2. Regularly wash your hands

Conjunctivitis (pink eye) is often caused by germs and bacteria carried to your eyes by unclean hands. Frequently washing your hands with soap and warm water helps keep bacteria away and prevents eye contamination. Prior to inserting or removing contact lenses, make sure to wash your hands with mild soap and dry them using a lint-free towel.

3. Beware of UV rays

By exposing yourself to sunlight and UV rays, you increase the risk of developing macular degeneration and corneal sunburn. Beyond just adding some style and zest to your look, sunglasses should protect your eyes from dangerous UV rays. Speak to your optometrist about the different options available for people who wear prescription eyeglasses or contact lenses too, to keep your eyes safe in the sun.

4. Stay hydrated

Staying hydrated is crucial for your body’s overall health and wellbeing — and that includes your eyes. Among other complications, if you don’t have enough fluid in your body, it impacts tear production and can cause dry eyes and irritation. Drink up!

5. Don’t smoke cigarettes

Need some extra motivation to quit smoking?

Smokers are more prone to developing age-related macular degeneration, cataracts, and other eye conditions. Cigarette smoking can also destroy optic nerves, which can adversely affect your vision over time. So think twice before you light up, and speak to your doctor about getting help to quit.

6. Eat a healthy diet

Eat plenty of fruits and vegetables to ensure that your diet is rich in antioxidants, such as Vitamins A and C. These can be found in leafy greens (your mom was right about spinach!), orange vegetables (think, carrots and sweet potato) and citrus fruit. Furthermore, fatty fish like salmon contain essential omega-3 fatty acids which also promote excellent eye health.

7. Keep a healthy distance from screens

Nip digital eye strain in the bud by positioning your computer monitor about an arm’s length away from the eyes and 20 degrees below eye level. Ideally, work in a room with enough diffused lighting to reduce stress on your eyes from the computer light.

8. Remember the 20-20-20 rule

Speaking of computers, have you heard of the 20-20-20 rule? When using digital devices, rest your eyes every 20 minutes by looking 20 feet away for 20 continuous seconds.

Once you’re at it, blink 20 times in succession to prevent dry eyes, and make it a habit to rise from your seat and take 20 steps to promote good posture and blood circulation, which helps your vision too.

9. Be careful with eye make-up

Make sure that your eye shadow, mascara, and eyeliner don’t cause your eyes an allergic reaction. Get in the habit of removing your make-up before going to sleep in order to avoid bacterial build-up from residual make-up left in the eye area. And, from time to time, clean your make-up brushes, especially those used to apply cosmetics around the eye area.

10. Sleep is golden

Just as with the rest of your body, your eyes need a break. So make sure that you get sufficient shut-eye (8 hours) each night to keep your eyes revitalized and healthy.

11. Wear protective eyewear

Whatever you do, make sure your eyes are well-protected. If you’re swimming, wear goggles to prevent chlorine from entering your eyes. If you’re gardening or engaged in a DIY project at home, wear safety glasses to keep dust particles and bacteria at bay and prevent eye injuries. Ask your local eye doctor about protective eyewear for sports and other activities.

12. Regularly visit your eye doctor

Don’t underestimate the importance of getting a routine eye exam, whether you need an updated prescription or not. Even if you can see well today, a comprehensive eye exam can pick up early signs of eye diseases and conditions before symptoms become noticeable, such as glaucoma, diabetes, retinal holes which could lead to retinal detachment, and cancers like melanoma. Early detection and management can prevent further complications and serious vision loss down the line.

Only an eye doctor has the required knowledge, experience, tools and techniques to determine whether you have these or other eye conditions.

It is recommended that everyone gets a comprehensive eye exam once a year (or at least every two years). Children, whose eyes are rapidly developing, and people at higher risk for developing eye problems such as diabetics and older people, need to undergo eye exams even more frequently: at the minimum, yearly.

During the evaluation, the eye doctor will check for things like:

Farsightedness, nearsightedness, astigmatism and/or presbyopia
Eye coordination
Optic nerve and eye pressure tests to spot glaucoma

It’s also important to be on the look-out for any changes in your vision. If you experience hazy or double vision, worsening eyesight, red eyes, eye pain, swelling or floaters, contact Dr. Ben-Nissan.

Incorporate these tips and habits into your lifestyle to maintain healthy eyes and a high quality of life. BenNissan Eyes offers comprehensive eye exams in North Miami Beach, Florida, and will be happy to answer any questions you may have about ways to maintain healthy vision.

Wearing Colored Contact Lenses This Halloween? Beware and Take Care!

Countless adults, teens and even children will be wearing colored contact lenses this Halloween, but few are aware of the risks involved. Ever wondered what those cat-eye contacts are doing to your eyes? If you got them without a prescription, beware of health complications.

Enjoy a safe and happy Halloween by educating yourself and others about the dangers of wearing colored contact lenses without a prescription.

Why Can Over-The-Counter Colored Contact Lenses Cause Eye Damage?

Contact lenses made to change one’s appearance go by many names: cosmetic, theatrical, Halloween, circle, decorative, colored, or costume contact lenses. While it’s illegal to sell colored contact lenses without a prescription, authorities rarely enforce the law — which means they’re still accessible in many places.

Many people believe that wearing non-prescription color contact lenses can cause no harm. This unfortunate myth has led to many contact lens complications. For instance, when a person feels that a contact lens is “dry”, it could be because the lens is not a good fit. Ideally, the lens should follow the contour of the eye, and stay centered, with enough lens movement to allow tear exchange beneath the lens.

Furthermore, non-medical colored contact lenses are often produced by unlicensed manufacturers that tend to use inferior plastic and toxic materials, such as lead (often used in lens coloring), which can get absorbed through the eyes into the bloodstream. These illegal lenses may also contain high levels of bacteria from unsanitary packaging, shipping, and storage conditions.

Therefore, purchasing any kind of contact lenses without a prescription or medical oversight can result in a variety of eye complications, such as corneal abrasions, eye sores, conjunctivitis, other eye infections, vision impairment and, in rare cases, even permanent vision loss.

Even if you have perfect vision, all contact lenses, including colored contacts, require a prescription and proper fitting by an optometrist.

Contact us at BenNissan Eyes and make an appointment with Dr. Ben-Nissan to get properly examined for a contact lens prescription.

The Dos and Don’ts of Colored Contact Lenses

DO make sure you undergo a comprehensive eye exam by an optometrist who will measure your eyes and properly fit you for contact lenses.
DO get a valid prescription that includes the measurements, expiration date and the contact lens brand name.
DO purchase the decorative contact lenses from a reliable retailer (hint: they should demand a prescription.)
DO follow the contact lens hygiene directives (cleaning, inserting and removing lenses) provided by your eye doctor.
DO make sure to undergo follow-up eye exams as directed by your eye care professional.
DON’T ever share contact lenses with anyone else.

So don’t let an eye infection get in the way of your fun this Halloween. Wearing decorative lenses without a valid prescription can result in serious harm to your eyes, which can haunt you long after October 31st.
