Do You Really Need Blue Light Glasses?

by Mehmood Ali


Blue light glasses are a relatively new product that claim to improve your sleep, reduce eye strain and protect the eyes from potential damage caused by exposure to blue light. While there are many products in this space, Blue Light Glasses is one of the most popular options available right now.

What is blue light?

Blue light is a type of light that you can see. It’s part of the visible spectrum, which means it has wavelengths ranging from 400 to 700 nanometers (nm). Blue light is produced by artificial sources such as halogen lamps or fluorescent bulbs, but it also comes from natural sources like the sun and sky.

Blue light can be harmful because it damages your eyesight and retina over time. This damage causes vision problems such as blurred vision or difficulty focusing on objects at distance or nearsightedness (nearsightedness).

How does blue light affect sleep?

Blue light is the same wavelength as the sun, which means that it’s not only visible to our eyes but also has a strong effect on our body. Blue light suppresses melatonin production and can affect your circadian rhythm. It also affects hormones like cortisol and testosterone, thereby affecting your natural sleep cycle.

Does blue light exposure cause permanent damage to the eyes?

Blue light is a form of high-energy visible light. It’s produced by the sun, other light sources like fluorescent bulbs and LED lights, and can damage your eyes if you’re exposed to it for an extended period of time.

The retina and macula are two parts of your eye that play a key role in color vision; they hold onto information about color as you look at something. If these areas become damaged by blue light exposure (which causes oxidative stress), they may not be able to keep up with the amount of information being sent from them to your brain—which would lead to loss of visual acuity and other symptoms such as headaches or fatigue after prolonged periods outdoors during daylight hours

Do blue light glasses work?

While the science is still out, there’s no doubt that you can benefit from wearing blue light glasses. Here’s what we know:

  • Blue light glasses block out some of the harmful blue spectrum that can cause eye strain, headaches and fatigue. They may also help you sleep better at night by blocking out short wavelength light emitted by electronics or smartphones and other electronic devices before they reach your eyes.
  • They’re great for reducing eye aches caused by long hours in front of a computer screen or reading too much on your phone before bedtime!

The real question is: do they work? It turns out there isn’t much research on this topic yet—but if anything else works better than regular eyeglasses (which are designed to filter UVA/UVB rays) then why not try them?

Blue Light Glasses may help prevent health problems.

Blue Light Glasses may help prevent health problems.

There is some evidence that blue light glasses may help you sleep better and get a better night’s sleep. Blue light is the part of the spectrum that comes off of our cellphones, tablets and computers. It’s also what we see when we look at screens in the evening or before bedtime. This can disrupt our circadian rhythms (our body temperature cycle) and make it harder to fall asleep or stay asleep if exposed to too much blue light during insomnia hours (9pm-3am).


We’ve all heard the scary news that blue light is harmful and can cause permanent damage to your eyes. But does this really happen? And if so, how do we know for sure? The answer to both questions is yes — in some cases. Blue light can cause harm to your eyes if you have particular eye diseases like macular degeneration or glaucoma, but there are other reasons why you might want to wear blue-light blocking glasses like yourself: They may help prevent health problems such as sleep disorders, headaches and migraines caused by too much exposure during the day time hours when…
