Block the Blue Light

The truth is, blue light isn’t all bad. It shouldn’t be blocked at all times. It can help memory, boost alertness, and elevate your mood! Still, the eye cannot take blue light all day long and it can easily contribute to eye strain especially when it is coming from computer screens and tablets and cellphones.

These days, we’re working, learning, and relaxing in front of screens emitting blue light all throughout the day—and night. Even your average indoor lightbulb can give off blue light.

You’re probably wondering. Okay, but what is blue light anyway?

Blue light is the highest energy visible light on the UV spectrum, and before the advent of technology, the sun was our only significant source of blue light. Problems arise, however, with the amount of blue light to which we are exposing our brains and bodies, potentially causing undue stress to our eyes and even making it hard to sleep at night.

There are a few ways to avoid this strain. First, let us introduce you to one of the best options on the list: blue light blocking lenses.

What are blue light blocking lenses?

Good question. Glasses equipped with lenses with blue light protection are a simple solution to combat the symptoms caused by increased screen time. The technology in these lenses has a subtle tint that softens harsh blue light rays as they pass through, reducing the amount of blue light to which the wearer’s eyes are exposed. They aren’t heavy or thick and can be made without a prescription attached to them. They can be made to fit adults, teens and children and are safe for all to wear. All blue light blocking glasses aren’t made the same. They can be made to block a certain percentage of blue light. How much you decide to block, well, that is up to you. Give our practice a call and we will gladly talk you through your options!

What else can I do to block blue light?

While you won’t be able to block it without the correct lens as your shield, you can still manage it.

When working at a computer, for example, you’re often looking up and down, from screen to paper, and your eyes are moving around and refocusing time after time. This is where the 20-20-20 rule can come into play. For every 20 minutes you’re in front of a screen, turn your head and look at something at least 20 feet away for 20 seconds. Just, give your eyes a break.

Another option: simply lower the brightness. The display settings for your screen on your phone or computer allow you to adjust the amount of light seeping from the screen. If your screen looks like a light source, lower the brightness. If your screen looks dull and a bit too dark, it’s okay and probably for the best to brighten it up. A dull screen can also strain your eyes.

Bottom line, protect your eyes the best way you can and remember that we are here to help! Looking to get a pair of blue light protection glasses that fit your lifestyle and your budget? Here at Infinity Eye Care, we can customize any style of frame and lens prescription with blue light-blocking technology.

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 almost always results in severe visual loss. There now are several medications that when injected into the bleeding eye can arrest the bleeding and potentially improve vision.

Glaucoma: The second leading cause of legal blindness in the United States is often called "the silent thief of sight." With glaucoma, there is often severe damage to the optic nerve before a person recognizes he is having a problem. Usually by the time a person notices symptoms, 70% of the optic nerve is destroyed. As of now, once that damage has occurred it cannot be reversed. This makes early diagnosis absolutely critical to saving your sight. In most cases (but not all) early detection and treatment can preserve functional vision throughout your lifetime.

Diabetic Retinopathy: This is another leading cause of legal blindness that has no visual symptoms until the disease is in its advanced stages. Every diabetic should have an annual eye exam to check for signs of retinal disease. If detected and treated in its early stages, the disease can usually be controlled and the vision preserved.

As you can see, there are very strong reasons to have your eyes examined regularly - especially as we age - in order to keep good visual health and function throughout your lifetime.
