Blue Light Blocking Glasses: Do you need ’em?

DIFF Blue Light Blocking Glasses

What is blue light?

Blue light is the portion of the visible light spectrum that has the shortest wavelengths and highest energy. Like the ultraviolet radiation, it has both dangers and benefits.

Sunlight is the main source of it, and being outside is where get the most exposure. But there are a growing number of man-made, indoor sources of blue light as well, like fluorescent and LED lighting, flat-screen tvs, laptops, iPhones, etc., that might be problematic.

Screens produce significant amounts of blue light and our prolonged exposure is the real problem. Sure, blue light from screens is only a fraction of what’s emitted by the sun, but the unnatural amount of time we spent glued to them is what has peeps concerned about the possible long-term effects of it on eye health.

What are blue light blocking glasses?

Apparently, our eyes are not very good at blocking blue light. Good at blocking UV rays? Yes. Less than one percent of UV radiation from the sun hits our retinas, even if we’re not wearing sunglasses. But, virtually all blue light passes through the cornea and reaches it. Bleh. Combine this with 10 hours days in front of a computer screen and you’re looking at a whole lotta eye strain and potential long-term damage.

Why you might want to try them.

So this is kinda scary: laboratory studies have shown that too much exposure to blue light can damage light-sensitive cells in the retina. This causes changes that resemble those of macular degeneration (←- the worst). Health professionals are worried that prolonged, unnatural amounts of exposure to blue light may increase a person’s risk of M.D. later in life.

And it turns out, its relatively easy to block them. You can get filters for your devices that prevent significant amounts of blue light emitted from screens from reaching your eyes. Or computer glasses, like the ones I just got, can be helpful too. You can get them without prescription if you have no need for vision correction. Or you can talk to your eye doctor about how to best combine blue light safety with your current vision correction situation.

Where I got mine.

I was literally scrolling through Instagram with one eye open, at like 5:30 am, in the dark when I saw an ad pop up for these cute glasses that promised to ease my digital eye strain. So click, tap, click, cc code, ‘complete transaction’ and they were delivered to my door.

How I’m liking them.

I love them. I think they’re so cute. I secretly always wanted to have classes as a cute accessory when I was little and now I have an excuse to wear them! It’s funny too cause when I try to take a selfie, the actual blue light is reflected in the lenses so, it seems as though they’re working. Yay!

These are a lovely addition to my personalized self-care routine for sure.

What about you? You ever tried any blue-light blocking technology? Did you notice a difference? I have. Even if it’s placebo effect, I don’t care. I def notice a difference in my eyes not feeling so strained by the end of the day.

There's more where that came from.
