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.

Begin Booking an Appointment

Despite requests that patients bring their current glasses to their office visit, many show up without them.

Sometimes it’s an oversight: “I was rushing to get here and forgot them”; “I left them in the car”; “I picked up my wife’s glasses instead of mine by mistake.” Doctors have heard them all.

Sometimes it is unavoidable: “I lost them”; “They were stolen”; “I ran them over with the car”; “I left them on the roof of the car and drove away and now they are gone.”

Frequently, however, it’s intentional. There is a perception by some people that if they don’t like their current glasses or feel like they are not working well for them that they are better off having their eye doctor start from scratch. “Why would I want the doctor to utilize a pair of glasses I’m not happy with as a basis or starting point for my next pair of glasses?”

But bringing your glasses to an appointment is important.

There are two main reasons for eye care professionals to know what your last pair of glasses were.

The first is to see what type of glasses they are and how you see out of them. Are they just distance? Just reading? A bifocal? A trifocal? A progressive?

Even if you feel they aren’t working for you it is essential for doctors to know the type of lens you had previously. It is also important to know how you see out of them and what the previous prescription was. This can help eye care professionals determine a new prescription that will work better for you.

The second reason doctors like to know what was in your last pair of glasses is that the majority of people who wear eyeglasses have some degree of astigmatism in their eyeglass prescription.

A significant change in either the amount or axis of the astigmatism correction from one pair of glasses to the next is often not tolerated well, especially in adults. If you make too much change from the previous prescription many people experience a pulling sensation in their eyes when they wear the new glasses. It can cause symptoms of eye strain, headaches, and distortion, making flat objects like a table look like they are slanted.

Many of the problems that occur when we try to give someone a new eyeglass prescription could be avoided if doctors knew the last prescription and how you did with it.

Anytime you are going to the eye doctor, it is essential to bring your most current pair of glasses with you to the exam--whether you love them or hate them!
