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.

Many people can recall the 1980s song by Thomas Dolby, that includes the lyrics,

”She blinded me with science! And hit me with technology....”

In the 21st century, it seems that the blind can now “depend” on and anticipate science to restore vision.

Scientific advancement in the arena of neuroscience and medicine have given blind people hope that they never had before. The world of science and technology is providing inroads into greater opportunities in the advancement of sight restoration and retinal prosthetics with measured success.

Global statistics show nearly 40 million people are affected by some sort of blindness, with 15 million debilitated by AMD alone. The advancement of Age Related Macular Degeneration (AMD) has sparked new research options for the blind, paving the way to future bionic eye treatments. Using eyeglasses with a camera that transmits images to an electrode implanted in the retina, images and movement can be detected. The Argus II, a retinal prosthesis device, is already available in the US and European markets with FDA approval in the United States.

Making a bionic eye is trickier than you think. The implant must not only respond to light, but also transmit the light to the neural pathways in the brain in order to process the light and subsequent vision.

The way our vision should work, is that light and images are processed through the, “film of the camera”, per se, called the retina. The retina relies on photoreceptors called rods and cones that take the visual image and transfer it through neural pathways to the brain, which in turn processes the vision causing us to see light, color, and images. The pathways of vision are processed through the second cranial nerve, the optic nerve. Scientists are working to restore those pathways damaged by glaucoma, stroke, head injury, and retinal disease or damage.

Advancements in this technology can lend to improvements in locating or identifying objects, orientation and mobility, detecting light and making certain household tasks easier, like locating utensils.

Although this technology is in its infancy, results are promising......and who knows, maybe in the future the Thomas Dolby song will need to be sung as “She UN-blinded me with science.”
