Imagine this – you go outside on a beautiful sunny day and realize that you left your sunglasses at home – ordinarily you would be squinting and uncomfortable but not anymore – now your contact lenses turn dark when you go outside! Acuvue Oasys, the wildly popular two week contact lens from Johnson and Johnson has joined technological forces with Transitions Optical to create Acuvue Oasys with Transitions. This new product got so much positive buzz that it was selected by Time Magazine as one of 2018’s BEST INVENTIONS OF 2018. Like the regular Oasys lens, the Oasys with Transitions is a two week lens that can be cleaned with either standard multipurpose solution or a hydrogen peroxide based system. It takes 30 seconds to activate when you go outside and ninety seconds to turn back to clear when you go back inside. When the lens is fully activated outside it filters 70% of outdoor light, and even inside it filters about 15% of indoor light. One important thing to realize is that although you are indeed blocking UV light on the eyeball itself when you wear these contacts, you still need sunglasses to protect the skin around your eyes as well as the other parts of your eye, and the contacts never get as dark as real sunglasses. Acuvue is recommending this lens for any patient who is bothered by light sensitivity, whether indoors our outdoors. They are also recommending it for patients who experience halos and starbursts when they drive at night, as well as to those who are bothered by computer lighting. The lens does change your eye color slightly when it is activated outdoors and in studies that were conducted on patients who tried this lens only 2% were bothered by the color shift.

Okay guys, here’s the scoop – there is no such thing as pink eye. Oh sure, your eye can be pink, but “pink eye” is not a diagnosis, it’s a description of the way your eye looks. So now that we’ve cleared that misconception up, what causes eyes to become pink?
One of the most common causes of pink (or red) eyes is some form of conjunctivitis. The term conjunctivitis is also very nonspecific and vague – so let’s break it down into more understandable terms. The conjunctiva is the clear thin covering of the white part of the eye and the insides of the lids and the term “itis” derives from the Greek and means “inflammation of”. So quite simply, conjunctivitis means that the white part of the eye is inflamed, and when body parts become inflamed, they get red or pinkish. There are three main forms of conjunctivitis:
- Bacterial Conjunctivitis – like it sounds, it’s caused by bacteria – not only is the eye red but there is usually green discharge as well that can cause the eyes to be glued shut upon awakening in the morning. This is pretty contagious and is treated with topical antibiotic drops or ointment.
- Viral Conjunctivitis – caused by viruses, the eyes are watery, red and sometimes itchy. This is also very contagious and since it is a virus, antibiotic drops don’t work. This usually runs its course over a week or so – cool compresses and artificial tears can be helpful.
- Allergic Conjunctivitis – the hallmark symptom of this type of conjunctivitis is unbearable itching. Usually this is a reaction to pollen or ragweed during peak allergy season (spring or fall) or to pets, dust, or other known allergens. It is not contagious and can be treated conservatively with cool compresses or high quality artificial tears. Oral antihistamines are helpful if there is also nasal congestion and sneezing, prescription eye drops work best if it only affects the eyes.
Other causes of pink or red eyes are dry eye and blepharitis (inflammation of the eyelids) as well as contact lens complications which can range from infections to corneal ulcers. Environmental causes of pink eye are irritants such as dust, smoke, air pollution and chemical exposure. It is important not to self diagnose or use somebody else’s eye drops. If your eyes get red or pink and your symptoms are getting worse or not going away it is important to have your eyes checked by an eye doctor to ensure proper and prompt treatment.
Age Related Macular Degeneration (AMD) is one of the leading causes of vision loss in patients over the age of 60 in the United States. Since February is AMD awareness month let’s talk a little about the detection, diagnosis, and treatment of this potentially visually devastating condition. The macula is the central part of the retina and if it is damaged central vision becomes impaired. There are two types of AMD, one is “dry” and one is “wet”. Dry AMD comprises roughly 90% of AMD patients and is characterized by thinning of the central retina and deposition of yellow spots (called drusen) in the macula. Although dry AMD is slow to progress and vision loss may be minimal, it can progress to a more intermediate or advanced form of dry AMD which can then progress to wet AMD. Wet AMD happens when abnormal and fragile blood vessels grow underneath the retina and then bleed (this is why it is called ‘wet’) causing destruction of the central vision. Dry AMD has no treatment per se, however there are lifestyle changes that can be taken in order to deter the progression from dry to wet. These lifestyle changes include smoking cessation, UV protection such as sunglasses, and ingestion of nutrients such as lutein and zeaxanthin in foods such as spinach or kale or in a vitamin supplement. Wet AMD is treated with drugs that are delivered into the vitreous (inner jelly like portion of eye) and go under the the broad umbrella term of “anti-VEGF” agents. Laser treatments and PDT (photodynamic therapy) are other treatments utilized in wet AMD.
Symptoms of macular degeneration include blurry vision, darkening of vision, loss of color vision and visual distortion. Once the central vision is lost, there is no way to restore it and low vision devices such as telescopes and magnifiers can be helpful to maximize the remaining vision. Early detection of AMD is crucial in order to preserve central functional vision which is why yearly eye exams are so important.
One of the biggest perks of being in the optical business is that I have a million pairs of glasses (only a slight exaggeration). While multiple pairs of glasses definitely contribute to a stylish wardrobe, there are more important reasons to have more than one pair. The same way that you wear different shoes for different activities, you need different types of glasses for different visual tasks. High heels don’t work for marathons, flip flops don’t work for an interview, and when was the last time you saw someone wearing snow boots at the beach?
The most important second pair of glasses should be a quality pair of sunglasses – these are available in both prescription and plano (fancy word for non-prescription) as well as in single vision and progressive (for reading at the beach). Many of us who are on the computer for extended periods of time benefit from a specific pair of computer glasses which would incorporate an anti reflective coating with a blue light filter to help mitigate fatigue. I always tell patients to measure the exact distance between their eyes and the computer screen so we can come up with the optimal prescription. There are also special progressive designs for people who use multiple computers at multiple distances. People with hobbies sometimes have very specific needs as well. The musicians in my practice bring in their instruments and music stands and we calculate in real space what the perfect prescription should be (we have often been treated to impromptu concerts!) Crafters like myself who enjoy knitting and watching TV at the same time often need a specific pair of glasses as well. Fashion is another reason to have multiple pairs of glasses.
Going back to my shoe analogy, certain styles are intrinsically casual and would not work well at a formal event (like sneakers with a ball gown). Different colors and shapes as well as the addition of details such as crystals or interesting hardware elevate a frame from merely functional to spectacular. Building a glasses wardrobe is a creative as well as practical way to express your individuality. Our well trained staff will help you select the perfect pair(s) of glasses which will harmonize fashion, function, and fun!
We know that excess sugar is bad for diabetics so patients with diabetes turn to foods with artificial sweeteners to get that burst of sweetness without the dangers of sugar. A recent study in the journal Clinical and Experimental Ophthalmology has reported a linkage between diabetics who drink more than four cans of diet soda and the development of the blinding complications of diabetic retinopathy (severe leakage of blood vessels in the eye). It was not associated with the development of the less severe eye complications of diabetes or macular edema which is swelling in the central part of the eye.
This study is pretty scary. Diabetics rely on these artificial sweeteners on a daily basis to keep them safe from sugar and here is a study that says that these sweeteners can cause severe eye complications. Now what? This research is very new and the results have to be repeated in order to make definitive decisions about cutting sweeteners out of a diabetics diet. A confounding factor in the research also notes that people who consume a lot of artificial sweeteners also have a higher body mass index (they weigh more) as well as a worse cardiovascular profile. In other words, more studies are needed.
So if I am diabetic and drink a lot of diet soda what do I do now? Admittedly this is a tough call. It would probably be wise to cut down the consumption of diet soda and try to switch over to water and stay tuned for further studies to be done.
