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.

Now that you have picked up your new pair of prescription eyeglasses, your focus becomes taking care of them. This is a task many disregard, but it is absolutely imperative that you make sure you are following a couple simple steps to keep the quality of your vision with your new spectacles.

We are all guilty of using a garment when in a rush to wipe away a pesky smudge on our glasses. This act is unfortunately the worst thing you can do for your lenses.

No matter how clean your clothes are, dust particles and even small bits of sand and debris cling to them. Since eyeglass lenses are not made of diamonds, these tiny little particles can do tremendous amounts of damage to your new lenses. The smallest little crumb can grind a scratch directly in your line of vision, which in turn can render your glasses almost useless.

Most of us know what it feels like trying to concentrate on the world in front of you when there is a little scratch distorting and distracting your vision. A majority of the time, these little scratches can be avoided by following a few simple steps.

You may have noticed while shopping in your favorite store that they sell a variety of eyeglass cleaners. You need to be careful because the sprays and wipes which you can purchase in retail stores are not necessarily approved for all types of eyeglass lens materials.

This factor makes them fall under that category of products that many eye care professions cannot recommend. Most of these liquids contain a form of acetone or other cleaning agent that is too harsh for plastic lenses. Many years ago, when all eyeglasses were actually made out of crown glass, these products would have worked just fine. Now, during a time where they have developed thinner, lighter materials like cr-39 plastic and polycarbonate, these products have proven to be too hard on the lenses.

Over time, the lenses will start to break down if exposed to the chemicals used in these sprays, causing a fogging effect. Once again, you are left with a pair of glasses that are now unable to be worn.

Now that we have gone over the two main culprits in the destruction of eyeglass lenses, other than accidents, let’s focus on some tips to extend the life of your glasses.

Most importantly, you should use an eyeglass case. For the large portion of patients who wear their glasses all day, it’s understandable how awkward it can be to carry a case around. But it’s nowhere near as frustrating as realizing the new pair of eyeglasses you just purchased is becoming scratched and ruined.

Also, you do not need to carry the case with you everywhere you go. Strategically leaving a case on a bedside table, in your car, or in a purse is the difference between “life or death” for your glasses.

This is also a simple way to clean your glasses that does not require you to purchase anything you probably don’t already have at home. Using lukewarm water at the sink, place a small, pea-sized dab of dish soap on your fingers. Gently rub the soap on both lenses from side to side, and then rinse with warm water. A disposable paper towel is recommended to dry the glasses.

Disposable towels work because they are just that, disposable - which guarantees they are not carrying dirt or sand from a prior use.

Taking care of your glasses today means you have them for clear vision tomorrow and into the future.
