Christmas is one of the most joyful times of the year… thoughts of cookies, decorations, family gatherings, and toys abound. Birthday parties for kids add to the list of wonderful memories as well. But there are a few toys that may not make memories so fun because of their potential for ocular harm. The American Optometric Association lists dangerous toys each year to warn buyers of the potential harm to children’s eyes that could occur because of the particular design of that toy.

Here is a sample of that toy list:

• Laser toys and laser pointers, or laser sights on toy guns pose serious threat to the retina, which may result in thermal burns or holes in the retina that can leave permanent injury or blindness. The FDA’s Center for Devices and Radiological Health issues warnings on these devices at Christmas peak buying times.
• Any type of toy or teenage gun that shoots a projectile object. Even if the ammo is soft pellets, or soft tipped it can still pose a threat. Even soft tipped […]
  

Your Eyes Are A Precious Gift–Protect Them During The Holidays

“I want an official Red Ryder, carbine action, two-hundred shot range model air rifle!”

“No, you'll shoot your eye out.”

This line from “A Christmas Story” is one of the most memorable Christmas movie quotes ever. Funny in the movie, but the holiday season does present a real eye injury threat.

For those who celebrate Christmas, that risk begins even before the actual day.

Some of the most frequent holiday-related eye injuries come from the Christmas tree itself.

Holiday eye safety begins with the acquisition of the tree. If you are cutting down your own tree, please wear eye protection when doing the cutting–especially if you are going to be using a mechanical saw such as a chain saw or sawzall. You need to also be careful of your eyes when loading a tree on top of the car. It is easy to get poked in the eye when heaving the tree up over your head.

Once back at home, take care to make sure no […]

Many people prefer shopping online to shopping in stores for many of their needs.

With technology constantly improving and evolving, people tend to take advantage of the convenience of shopping online. Whether it’s clothing, electronics, or even food, you can easily find almost everything you need on the Internet.

Eyeglasses, unfortunately, are no different. Many online shops have been popping up in recent years, offering people that same convenience. But what they don’t tell you is that it comes at a price, and this article’s purpose is to shine a light on the negatives of shopping online for eyeglasses.

Here are some important reasons to avoid the temptation of ordering glasses online.

1. Accuracy–Instead of saving the most important point for last, we will start with the main reason that ordering eyeglasses online is a bad idea. Product accuracy is a huge reason that the online market has not completely taken off. Every person who needs eyeglasses needs to understand the process for how their prescription is obtained in order to truly understand why shopping online […]
   

Diabetic retinopathy, which is a complication of diabetes that affects the eyes, is detected during a comprehensive eye exam that includes:

• Visual acuity testing.
• Dilated exam in which drops are placed to widen the pupil to allow examination of the retina.
• Tonometry. Measurement of the eye pressure inside the eye.

Supplemental testing may include:

• Optical coherence tomography (OCT). This is a non-invasive test that images the retina to detect any fluid or diabetic macular edema.
• Fluorescein Angiography. This test involves an injection of a dye into your arm and a series of pictures that are taken as the dye flows through the retinal vessels. This may show leakage of fluid or the growth of new blood vessels in the retina.

Treatment for Diabetic Retinopathy

The best treatment is prevention of diabetic retinopathy by strict control of blood sugars. Once diabetic retinopathy is present, treatment of diabetic retinopathy will slow progression but won’t cure it.

Diabetic macular edema can be treated with several different therapies that may be used alone or in combination.

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, has come out with the first transition contact lens. Acuvue Oasys Transitions hit the market recently and while it is still brand-new technology, preliminary results have been generally positive.

Just a couple personal thoughts: It looks a little strange. The material itself turns a dark shade of grey and therefore […]

Diabetic retinopathy is an eye condition that affects the retina in people who have diabetes.

The retina is the light-sensitive tissue that lines the back of the eye, and detects light that is then processed as an image by the brain. Chronically high blood sugar or large fluctuations in blood sugar can damage the blood vessels in the retina. This can result in bleeding in the retina or leakage of fluid.

Diabetic retinopathy can be divided into non-proliferative or proliferative diabetic retinopathy.

Non-proliferative diabetic retinopathy: In the early stage of the disease, there is weakening of the blood vessels in the retina that causes out-pouching called microaneurysms. These microaneurysms can leak fluid into the retina. There can also be yellow deposits called hard exudates present in the retina from leaky vessels.

Diabetic macula edema is when the fluid leaks into the region of the retina called the macula. The macula is important for sharp, central vision needed for reading and driving. The accumulation of fluid in the macula causes blurry vision.

Proliferative diabetic retinopathy: As diabetic […]

In our modern world, people spend hours on end staring at computer screens, smartphones, tablets, e-readers, and books that require their eyes to maintain close focus.

For most people (all except those who are nearsighted and aren’t wearing their glasses), their eyes’ natural focus point is far in the distance. In order to move that focus point from far to near there is an eye muscle that needs to contract to allow the lens of the eye to change its shape and bring up-close objects into focus. This process is called accommodation.

When we accommodate to view close objects, that eye muscle has to maintain a level of contraction to keep focused on the near object. And that muscle eventually gets tired if we continuously stare at the near object. When it does, it may start to relax a bit and that can cause vision to intermittently blur because the lens shape changes back to its distance focal point and the near object becomes less clear.

Continuing to push the eyes to focus on near objects […]
