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?

It was the best of times, it was the worst of times. These famous words of Charles Dickens are playing out today more than ever in the area of technology.

We are living in the best of times to obtain knowledge at the push of a button. But smartphones, laptops, iPads, video games, smart boards, tablets can all add up daily total screen time. Research shows the impact can adversely affect your eyes, your focusing, your moods, and even your ability to sleep and relax. In fact, the American Academy of Pediatrics has recommended only two hours of screentime per day as a standard for children.

What are the symptoms of too much screen time on the eye, and how can you combat these symtoms?

Doctors are seeing an increase in dry eye syndrome because patients do not blink as often when they are staring at the screen for a prolonged period of time. This causes burning or watery eyes, rubbing of the eyes, and frequent headaches.

The key to combatting these symptoms is to consciously blink more, use rewetting eye drops, and take frequent breaks. Perform a visual exercise where every 5-10 minutes, you focus on a distant target for 10 seconds, then return to your screen. Your eye care practitioner can also recommend specialized computer lenses with anti-glare properties to mininmize fatigue.

It is important to reiterated that screentime is not bad if used with moderation and freqeunt breaks. In fact, many computer programs are used to help patients strengthen their eye muscles and promote hand eye coordination. So the key is to enjoy the use of your technology, and remember that balance is the key to life.

So take frequent breaks, and use preventative measures such as re-wetting eye drops, anti-glare computer lenses, and eye exercises to minimize negative impact of screen time on your precious eye sight.
