The Best of Blue Light-Blocking Glasses in 2021

The average person spends a lot, if not too much, of screen time each day. Whether it’s on your computer, laptop, TV, or phone, exposure to all of these devices can negatively affect your vision and sleep-related health.

The main reason for this is the intense blue light emitted by these devices: it puts pressure on the eyes, causes blurred vision, dizziness, headaches, and drains your sleep pattern.

The dangers of blue light

In addition to the apparent disruption of the sleep cycle, blue light has been implicated in something called digital eye load.

Constant exposure to light from devices can cause blurred vision and other symptoms, such as a burning sensation, staring, or tearing.


Long-term exposure can also cause dry eyes and tight muscles that help the eyes focus. This all happens because your eyes blink less often when looking at a screen.

Why wear blue light blocking glasses?

Blue light can affect us and our health if our exposure does not deteriorate. Blue light has shorter and brighter wavelengths than other colors in the visible light spectrum, and therefore its effects are similar to ultraviolet (UV) rays. The brain interprets the blue light from screens as sunlight and keeps us awake.

It naturally becomes an evening problem when the production of melatonin, a sleep-inducing hormone in the brain, slows down, resulting in a worn-out internal sleep clock (circadian rhythm) and a more inferior quality of sleep.

By blocking the intense blue light coming from these screens, these Blue light glasses can help the wearer’s brain to return to average melatonin production, achieve correct circadian rhythm, and other effects such as lowering eye pressure, resulting in headaches, blurry visuals, dizziness, and more.

2. Lens color

The intensity of the red tint on the lens can indicate its effectiveness at blocking the blue light. The redder and darker the glass, the more blue light it blocks. They should be used for bright blue light situations, such as in front of night screens.


During the day, lighter lenses are recommended as they do not cause noticeable color distortion. Think about the color of your anti-blue lenses depending on when you spend the most time in front of the screen.

3. The value

Glasses that block blue light are relatively inexpensive; Even better quality can be found for under $ 50, while the cheapest glasses can cost as little as $ 10. You don’t have to worry too much about the price as you need to find a good pair of glasses within your budget.
