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.

Siegfried and Roy’s white tiger dazzled us with its magic. Shamu, the famous killer white whale at Sea World dances upon the water to the amazement of crowds, and who can forget Benji or Lassie as childhood heroes. Have you ever explored the fascinating world of animal vision? Who wins the prize for the the most advanced visual species of the animal or insect kingdom? The results may surprise you.

We all agree that birds of prey (hawks, eagles, falcons etc.) have the best bionics hands down but have you ever considered the vision of the colossal squid, or the dragon fly, the ogre spider or mantis shrimp?

The colossal squid has an eye larger than any sea animal: it's the size of a basketball! The squid’s eyes and 3-D vision are so astute so that they can spy whales that would be predatory to them.

The dragon fly has incredible vision, better than any other insect. Take for instance the common house fly who has around 6,000 eye facets that give them an astounding panoramic view of the world. Amazingly, dragonflies have 5 times more eye facets than houseflys, giving them 30,000 units of panoramic viewing. With this skill, they can predict where their prey will be and get there before the other insect does, thus the dragon fly comes in as a leader of all insects in the "amazing vision contest“!

Consider the ogre spider next. The ogre spider, out of all other spiders has this unique feature: two large posterior facing eyes with six smaller eyes to see prey even in the dark. It's huge eyes have outstanding night vision, in fact, about 2000 times better than most spiders! This unique portrayal of night vision gives it the edge over many other species in hunting prey.

So how about the mantis shrimp? How can a shrimp have good eyesight you ask? They have the number one most complex visual system of any species known to man. Literally hi-definition vision! They have compound eyes with 16 photoreceptors (humans have 3) and they see all colors of the spectrum including UV and singular & circular polarized light.

This is like an electric 3-D light show on steroids! There is ongoing research on how they can see 3-D with only one eye and how they communicate visually.

Keys to researching different species vision may on day unlock mysteries into the human eye. Only the future will tell what nature may unlock for future vision breakthroughs.

Keep your eye on the tiger and other species for more vision breakthroughs in the future!
