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.

CHEERS to your ocular health!

Did you know that nutrition plays a vital role in your ocular health?

Cardiologists stress lean meats, red wine, and exercise for your heart health. But what about your eyes? Well, studies show there are distinct food groups that show extreme benefit to the well being of your vision.

Macular Degeneration is a condition of the retina in the back of the eye that causes symptoms of loosing the fine detail vision we have been used to, replacing it with a central scotomas or blind spots. Your central vision gets destroyed by this disease. Macular Degeneration is an inherited disease, as well as some cataract formations, so check your family history to see if you are at greater risk. Lutein, found in green leafy vegetables such as kale, spinach, and broccoli create an added insulation in your retina against macular degeneration. Yellow vegetables and fruit (squash, yellow watermelon) and Omega III supplements (fish oil or flax seed oil) also help boost the pigment cells in the macula to promote crisp vision. As a side note, it is best to purchase molecularly distilled fish oil, and take the pills at night to prevent unwanted GI effects or “fish burp” which occurs with less expensive, non distilled fish oils. Remember, not all fish oil pills are created equally.

What about preventing cataracts, the clouding of the natural lens of the eye that causes symptoms such as dim vision, glare at night, decreased focusing, and blurred vision? Well, studies have shown that the vitamin C found in citrus fruits such as oranges, lemons, grapefruit, and kiwi can slow down cataract formation. Cutting your UV exposure by wearing sunglasses with UV-A and UV-B protection will also help, as well as smoking cessation.

It's good to be aware of these vision conditions that affect millions of people worldwide, and to do your best to incorporate preventative care such as good nutrition, regular check ups with your eye care practitioner, and sun exposure prevention.

If you don’t have time to eat all those fruits and vegetables in a day consider a fruit or vegetable smoothie and then drink to your good ocular health!  Additionally, cooked food devalues the precious live enzymes, so these foods are best eaten raw.

Remember, you can play a vital role in your ocular health. As Hippocrates, the father of medicine, said, "Let your food be your medicine and your medicine be your food."
