The Care & Cleaning of Your Glasses

Now that you have picked up your new pair of prescription eyeglasses, your focus becomes taking care of them. This is a task many disregard, but it is absolutely imperative that you make sure you are following a couple simple steps to keep the quality of your vision with your new spectacles.

We are all guilty of using a garment when in a rush to wipe away a pesky smudge on our glasses. This act is unfortunately the worst thing you can do for your lenses.

No matter how clean your clothes are, dust particles and even small bits of sand and debris cling to them. Since eyeglass lenses are not made of diamonds, these tiny little particles can do tremendous amounts of damage to your new lenses. The smallest little crumb can grind a scratch directly in your line of vision, which in turn can render your glasses almost useless.

Most of us know what it feels like trying to concentrate on the world in front of you when there is a little scratch distorting […]

Am I Dealing with Allergies, Dry Eye, or Infection?

As an eye doctor, diagnosing a red eye can be challenging. Are we dealing with an infection, allergy, inflammation, or dryness?

A common question we get is, “Doc, my eyes are red, burning, itchy, and tearing. Is this dry eye or from allergies?” The short answer is it could be one, both, or neither. We'll outline various ways these conditions present clinically and the treatments for them.

The hallmark symptom of allergy – meaning if you have this symptom you almost definitely have the condition – is itching. Red, watery, ITCHY eyes are almost invariably due to an allergen, whether environmental or medicinal. It is one of the most common ocular conditions that we, as eye doctors, treat — especially when plants are filling the air with pollen as they bloom in the Spring and then die off in the Fall.

The itching occurs because an immune cell called a mast cell releases histamine, causing the itching sensation. It can be quite unbearable for the sufferer, causing them to rub their eyes constantly, which actually increases […]

Screen Time & Your Eyes

"It was the best of times, it was the worst of times." These famous words by Charles Dickens are playing out today in the area of technology.

We are living in the best of times when it comes to obtaining knowledge at the push of a button. But smartphones, laptops, video games, tablets, etc., can really increase our daily total screen time.

What are the symptoms of too much screen time for the eye, and how can you combat these symptoms?  Research shows that screen time can adversely affect your eyes, focus, moods, and ability to sleep and relax.

Doctors are also seeing an increase in dry eye syndrome because patients do not blink often enough while they are staring at the screen for a prolonged period of time. The lack of blinking can cause burning or watery eyes, rubbing of the eyes, and frequent headaches.

The key to combatting these symptoms is to consciously blink more, use rewetting eye drops, and take frequent breaks. Make it a priority to practice the 20-20-20 rule. For every […]

What to Do About Those Pesky Floaters

Do you have floaters in your vision?

Floaters are caused by thick areas in the gel-like fluid that fills the back cavity of your eye, called the vitreous.

Many people, especially highly near-sighted people, often see some degree of floaters for a good portion of their lives. Often, these floaters are in the periphery of your vision and may only be visible in certain lighting conditions. The most frequent conditions are when you are in bright sunlight and are looking toward the clear blue sky. I know this from personal experience since I have a floater in my left eye that I most often see when swimming outdoors. Every time I turn my head to the left to breathe I see this floater moving in my peripheral vision.

This is totally harmless other than when I’m swimming in the ocean and swear that sudden object in my peripheral vision is a shark bearing down on me. Some people who have floaters are not as lucky– the floater might be in their central vision and almost constantly […]

My New Glasses Are Too Strong!

Eye doctors typically pride themselves on being able to improve someone’s vision through glasses or contact lens prescriptions. Whether it’s a first-time glasses wearer, or someone having either a small or large change in their prescription, we like to aim for that goal of 20/20 vision.

Despite our best efforts, however, correcting vision to 20/20 is not always a positive outcome for the patient. Whether someone will be able to tolerate their new prescription is based on something called neuroplasticity, which is what allows our brains to adapt to changes in our vision.

You or someone you know may have had this happen: Your vision is blurry, so you go to the eye doctor. The doctor gives you a new prescription, but when you get your new glasses, things seem “off.”

Common complaints are that the prescription feels too strong (or even too clear!) or that the wearer feels dizzy or faint. This is especially true with older patients who have had large changes in prescription, since neuroplasticity decreases with age. It is also more likely […]

Transitions Contact Lenses

Transition lenses in eyeglasses have been around for many years now. The mechanics behind transition lenses is that certain chemicals in the lens interact with UV light from the sun and turn the lenses dark when you go outside and back to clear when you go inside.

This is a great accompaniment to sunglasses, as it is not always convenient to be carrying around multiple pairs of glasses with you, especially when going from inside to outside frequently. However, there are some drawbacks to transitions, including the fact that they don’t get as dark as sunglasses, have some difficulty turning dark in the car, and have a tendency to keep a slight constant tint even in dark conditions.

Vistakon, the optical wing of Johnson & Johnson, came out with the first transition contact lens a few years ago.  They work well for some people, and don't seem to do a lot for others.

Just a couple personal thoughts: It can look a little strange, depending on the person and the eye color. The material itself turns […]

What You Should Know About MIGS (Minimally Invasive Glaucoma Surgery)

For over 40 years the standard surgical treatment for glaucoma was a procedure called a trabeculectomy.

In a trabeculectomy, the ophthalmic surgeon would make a hole in the wall of eye to allow fluid from the inside of the eye to flow out of the eye and then get resorbed by the blood vessels in the conjunctiva (the mucous membrane that covers the white part of the eye).

This surgery often resulted in a large decrease in the Intraocular Pressure (IOP). Reducing the IOP is the goal of glaucoma surgery because multiple studies show that if you can reduce the pressure the progression of glaucoma slows.

The problem with trabeculectomy is that although it frequently lowers the pressure, it also has a fairly high complication and/or failure rate. This led to some reluctance to perform the procedure unless the glaucoma was severe, or the pressure was very high. As a result of those issues there has been a search during the last 40 years for something that had a lower complication rate and could be more […]

What Tests Might You Have During Your Eye Exam?

If it's been a while since your last eye exam–or if you've never had one done–it's always nice to know what testing you might have done and what issues the eye doctor looks for.  Here's the scoop on some common testing…

Visual Field

The visual field test is designed to check your peripheral vision, which isyour ability to see things where you are not directly looking.

When we test your vision on the basic eye chart, we are testing how well you see right in the center and it gives us no idea if you can see out away from the center. Your peripheral vision is very important because it gives you the ability to move around your environment without running into things.

There are several diseases that can severely impact your peripheral vision while leaving central vision unaffected. Some people can have perfectly normal 20/20 central visual acuity and have almost complete loss of their peripheral vision.

The main culprits that can have a big impact on your peripheral vision are glaucoma, some retinal diseases […]

Your Eyes + Lyme Disease

Lyme disease is an infection that is caused by a spirochete (a type of microorganism) called Borrelia burgdorferi, and more rarely by Borrelia mayonii. It is transmitted to humans by the bite of a deer tick.

The disease has a strong geographical incidence, being highly concentrated in the Northeastern United States and also in Minnesota and Wisconsin.  However, the tick's habitat has been spreading rapidly, and it is always a good idea to be cautious and consult medical help if you think you might have been bitten by a tick that could possibly be infected.

Lyme disease was first recognizedin the area of Lyme, Connecticut, in 1975. It can start with a characteristic “bull’s eye” rash, in which there is a central spot that is surrounded by clear skin that is then ringed by an expanding rash. It can also appear just as an expanding rash.

This rash usually starts within days of the tick bite. Eye problems can occur along with this rash in the first phase of the disease. This […]

How We Test Your Eye Pressure

A common question asked during the eye exam is, “When is the puff coming?”  

Patients are referring to air-puff or non-contact tonometry. Tonometry is the procedure used to measure eye pressure, and this is important for diagnosing and monitoring glaucoma.

In non-contact tonometry, a puff of air is used to measure the pressure inside the eye.  The benefit of this test is there is no actual contact with the eye, but the air puff is sometimes very startling for patients. Some people hate that test and it isn’t the most accurate way to measure your eye pressure.

Some doctors don’t even use the air-puff test. Instead, they place a yellow drop that consists of a numbing medicine and then shine a blue light on the eye. This is done in front of the slit lamp and a small tip gently touches the eye to measure the eye pressure. This procedure is called Goldmann tonometry and is considered the gold standard for measuring eye pressure.  

Another method for checking eye pressure is the Tonopen. This […]
