The Importance of Quality Sunglasses

The sun does some amazing things.  It plays a role in big helping our bodies to naturally produce Vitamin D. In fact, many people who work indoors are directed to take Vitamin D supplements because of lack of exposure to the sunshine. 

But being in the sun has risks, as well…

If sunglasses are not worn, there is a greater risk for cataracts or skin cancers of the eyelids. It is important to know that not all sunglasses are made alike. UV A, B, and C rays are the harmful rays that sunglasses need to protect us from.

However, many over the counter sunglasses do not have UV protection built into the lenses, which can actually cause more damage especially in children. 80% of sun exposure in our lives comes in childhood. Without UV protection in sunglasses, when the pupil automatically dilates more behind a darker lens, more of the sun's harmful rays are let in.

The whole point is that consumers should be aware that it is vital to buy sunwear that has UV protection […]

What Is a Punctal Plug and Why Would I Need One for My Eyes?

Punctal plugs are something we use to help treat Dry Eye Syndrome.  

This syndrome is a multifactorial problem that comes from a generalized decrease in the amount and quality of the tears you make.  There is often both a lack of tear volume and inflammation in the tear glands, which interfere with tear production and also cause the quality of the tears to not be as good.

We make tears through two different mechanisms.  One is called a basal secretion of tears, meaning a constant low flow or production of tears to keep the eye moist and comfortable.  There is a second mechanism called reflexive tear production, which is a sudden flood of tears caused by the excitation of nerves on the eye surface when they detect inflammatory conditions or foreign body sensations. It is a useful reflexive nerve loop that helps wash out any foreign body or toxic substance you might get in the eye by flooding the eye with tears.  Consider what happens when you get suntan lotion in your eye.  The nerves […]

Mom’s Eyes

Motherhood…the sheer sound of it brings enduring memories. A mother’s touch, her voice, her cooking, and the smile of approval in her eyes. Science has recently proven that there is a transference of emotion and programming from birth and infancy between a mother and her child–a type of communication, if you will, that occurs when the infant looks into its mother’s eyes. So what is this programming? How does it work and what effect does it have on the life of the child? What happens if it never happened to the infant? What happens if the mother is blind? These questions and more can be answered through a term called “triadic exchanges” in which infants learn social skills.

The gaze into a mother’s eyes brings security and well being to the child. When she gazes at another person, it makes the infant look at what she is gazing at, and introduces the infant to others in the world. This is known as a triadic exchange. So now their world is no longer just one person, their […]

The 3 F’s–and Why They Can Be So Dangerous

If you are seeing the 3 F's, you might have a retinal tear or detachment and you should have an eye exam quickly.

The 3 F's are:

  • Flashes – flashing lights.
  • Floaters – dozens of dark spots that persist in the center of your vision.
  • Field cut – a curtain or shadow that usually starts in peripheral vision that may move to involve the center of vision.

The retina is the nerve tissue that lines the inside back wall of the eye and if there is a break in the retina, fluid can track underneath the retina and separate it from the eye wall. Depending on the location and degree of retinal detachment, there can be very serious vision loss.

If you have a new onset of any of the three symptoms above, you need to get in for an appointment fairly quickly (very quickly if there are two or more symptoms).

If you have just new flashes or new floaters you should be seen in the next few days. If you have both […]

Do I Have Eye Allergies? If So, What Can I Do?

Ocular allergies are among the most common eye conditions to hit people of all ages.

Though typically worse in the seasons of Spring and Summer, some people suffer with allergies all year. This is especially true for people who have allergies to pet dander, mold, dust mites, and other common allergens that tend to linger throughout the year.

The hallmark sign of ocular allergies is itching.

While itching can be a symptom of other eye conditions, the likelihood that there is at least some allergy component to the condition is quite high. This seems to be particularly true when the itching occurs mainly in the inner corner of the eyes. This signals that the condition is allergy-related, whereas itching along the eyelid margin suggests other conditions.

Allergy itching is usually accompanied by redness, tearing, and string-like mucus discharge from the eye. When accompanied by rhinitis, sinusitis, and sneezing, people can truly suffer from their allergies – especially as it relates to the eye.

The good news is there are numerous avenues for relief from this annoying […]

Want to Know How to Make Your Red Eyes Redder?

Is it safe to use "Redness Relief" eye drops regularly?

The short answer is NO.

Here’s the slightly longer answer.

There are several eye “Redness Relief” products on the over-the-counter market, such as those made by Visine, Clear Eyes, and Bausch & Lomb – as well as generic versions sold by pharmacy chains.

Most commonly, the active ingredient in redness relief drops is either Tetrahydrozoline or Naphazoline. Both of these drugs are in a category called sympathomimetics.

Sympathomimetics, the active ingredient in redness relief drops, work though a process called vasoconstriction, an artificial clamping down of the superficial blood vessels on the eye surface. These blood vessels often dilate in response to an irritation. This increase in blood flow is trying to help repair whatever irritation is affecting the surface of the eye. Clamping down on those vessels by using a vasoconstrictor counteracts the body’s efforts to repair the problem.

The other downside to repetitively using redness relief drops is that after the vasoconstrictor wears off the vessels often dilate to an even larger degree than when the process started. This […]

There’s Blood in the Back of My Eye?!

What does blood in the back of the eye signify, anyway?

It could be a retinal vein occlusion, an ocular disorder that can occur in older people where the blood vessels to the retina are blocked.

The retina is the back part of the eye where light focuses and transmits images to the brain. Blockage of the veins in the retina can cause sudden vision loss. The severity of vision loss depends on where the blockage is located.

Blockage at smaller branches in the retinal vein is referred to as branch retinal vein occlusion (BRVO).  Vision loss in BRVO is usually less severe, and sometimes just parts of the vision is blurry.  Blockage at the main retinal vein of the eye is referred to as central retinal vein occlusion (CRVO) and results in more serious vision loss. 

Sometimes blockage of the retinal veins can lead to abnormal new blood vessels developing on the surface of the iris (the colored part of your eye) or the retina. This is a late complication of retinal vein blockage and can occur […]

Do I Even Need an Exam?

There are several treatable eye diseases that at their earliest onset have few or no visual symptoms. In fact, the three leading causes of legal blindness in the United States all start with almost no visual symptoms detectable by the person suffering from the disease. The three diseases are macular degeneration, glaucoma, and diabetic retinopathy. Each of these diseases gets more prevalent as people age. That is why the American Academy of Ophthalmology recommends regular eye exams at more frequent intervals as adults get older.

Macular Degeneration: The leading cause of legal blindness in the United States is a treatable but not curable disease. Early detection and treatment can significantly improve the long-term outcome. At the earliest stages, often when people are unaware that they have a problem, treating the disease with a very specific vitamin regimen called AREDS 2 can help. These vitamins have been shown to slow the progression of the disease and improve long-term outcomes. When the disease becomes more advanced there is the possibility of bleeding in the retina. If left untreated, that […]

Coronavirus and Your Eyes

Health and government agencies nationwide are warning people about the spread of the COVID-19 coronavirus and are they offering important advice on how to minimize your risks of contracting the disease.

Besides social distancing and isolating yourself from people who are ill, health experts are telling people to wash their hands and to keep them away from their eyes, nose and mouth.

Their advice is to wash your hands often with soap and water for at least 20 seconds, or to use a hand sanitizer with at least 60% alcohol. They also strongly emphasize to keep your hands away from your face, since your eyes, nose and mouth are passageways for germs to enter your system.

That means don’t rub your eyes, scratch your nose or put your fingers next to your mouth. And you’re right, it will be hard to avoid those things. Think about how often you might itch your eyes or watch others to see how often they do it.

How do you practice good eye health in these trying times?

Here are […]

Emergency Room Not Usually Best Choice for Red Eye

At some point, you might be the victim of one of these scenarios: You rub your eye really hard, you walk into something, or you just wake up with a red, painful, swollen eye. However it happened, your eye is red, you’re possibly in pain, and you’re worried.

What do you do next?

Going to the Emergency Room is probably not your best bet.

Your first reaction should be to go see the eye doctor.

There are many causes for a red eye, especially a non-painful red eye. Most are relatively benign and may resolve on their own, even without treatment.

Case in point: Everyone fears the dreaded “pink eye,” which is really just a colloquial term for conjunctivitis, an inflammation or infection of the clear translucent layer (conjunctiva) overlying the white part (sclera) of our eye. Most cases are viral, which is kind of like having a cold in your eye (and we all know there is no cure for the common cold).

Going to the ER likely means you’re going to be prescribed antibiotic […]
