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.

The American Academy of Ophthalmology has recommendations for how often adults need to get their eyes examined and those recommendations vary according to the level of risk you have for eye disease.

For people who are not at elevated risk the recommendations are:

  • Baseline eye exam at age 40.
  • Ages 40-54 every 2-4 years.
  • Ages 55-64 every 1-3 years.
  • Ages 65 and older every 1-2 years.

Those recommendations are just for people who have NO added risk factors. If you are diabetic or have a family history of certain eye diseases then you need exams more frequently.  

As you can see, the guidelines recommend more frequent exams as you get older. Here are the Top 4 reasons why you need your eyes examined more frequently as you get older:

1. Glaucoma

Glaucoma is the second leading cause of blindness in the United States. It has no symptoms when it begins and the only way to detect glaucoma is through a thorough eye exam. Glaucoma gets more and more common as you get older. Your risk of glaucoma is less then 1% if you are under 50 and over 10% if you are 80 or over. The rates are higher for African Americans. Glaucoma can be treated but not cured.  The earlier it is detected and treated, the better your chances are of keeping your vision.

2. Macular Degeneration

Macular degeneration is the leading cause of blindness in the U.S. Like glaucoma, it gets more common as you age. It affects less than 2% of people under 70, rises to 10% in your 80s and can get as high as 50% in people in their 90s. The rates are highest in Caucasians. Macular degeneration can also be treated but not cured. Early intervention leads to better outcomes.

3. Cataracts

As in the cases above, cataracts get more common as you get older.  If you live long enough, almost everyone will develop some degree of cataracts. In most people cataracts develop slowly over many years and people may not recognize that their vision has changed. If your vision is slowly declining from cataracts and you are not aware of that change it can lead to you having more difficulty in performing life’s tasks. We get especially concerned about driving since statistics show that you are much more likely to get in a serious car accident if your vision is reduced. There is also evidence that people with reduced vision from cataracts have a higher rate of hip fractures from falls.

4. Dry Eyes

Dry eyes can affect anyone at any age but the incidence tends to be at its highest in post-menopausal women. Dry eyes can present with some fairly annoying symptoms (foreign body sensation in the eye, burning, intermittent blurriness). Sometimes there aren’t any symptoms but on exam we can see the surface of the cornea drying out.  Dry eye can lead to significant corneal problems and visual loss if it gets severe and is left untreated.

One of the most heart-breaking things we see in the office is the 75-year-old new patient who hasn’t had an eye exam in 10 years and comes in because his vision “just isn’t right” and his family has noticed he sometimes bumps into things. On exam his eye pressures are through the roof and he is nearly blind from undetected glaucoma. And at that point there is no getting back the vision he has lost. If he had only come in several years earlier and just followed the guidelines, all this could have been prevented. Now he is going to have to live out the rest of his years struggling with severe vision loss.

DON’T LET THAT BE YOU!!!!!!
