How to choose the right blue light glasses

When we spend more and more time at home and staring at the screens, we become more prone to eye strain. You’ve probably heard of the blue light and how it can hurt your eyes, and maybe a pair of blue light blocking glasses caught your attention. But to understand that there are many options to reduce eye strain while staring at the screen, and they go out to get new lenses. Here are some tips to help you get the most out of your blue light.


What is blue light?

At the most basic level, the blue light looks like: the light is that blue. It’s not a complete picture, though, and that’s where the theory of light and theory comes into play, along with concepts such as color temperature, Planck’s constant, and the black body’s radiation curve. Without going too far into the weeds, you just need to understand one fact about light: the color white is not universal.

There is no single white, but the whole range of visual light that counts as white. Depending on the state of the light and what is illuminated and the light reflected, white light appears in a very yellow (warm) or blue (calm) color. For example, the light coming from a heated LED light bulb is hotter than the light coming from a computer monitor. This is called color temperature, and it is measured in Kelvin (K).

What we normally see as a white light shift with a range of 2,700 to 2,000. Illusively, hot light has a lower temperature than cold light, tungsten is hit around 2,800K with a near-fire glow, and sunlight hits, 000,000.

Computer monitors usually set the white to a very cold temperature to mimic natural sunlight, close to 50,000K. This means that the light from your screen is very blue, which you will see if you look at a warm light bulb with a white background from a web page. Blue light has been accused of causing eye strain and eye injuries, so naturally the solution should be bright before hitting your eye.


Is the blue light that bad?

Here it is difficult, with many assurances from the manufacturers of blue light blocking glasses which must be medically examined. Basically, a blue light can’t directly damage your eyes. Of American Academy of Ophthalmology Note that ultraviolet radiation can damage the eye, but computer monitors and other screens do not actually emit that type of radiation. Blondes are beautiful, but they are not really harmful. In fact, AAO No special eyewear is recommended For computer use.

This does not mean that you should simply ignore the impact on the screen all day long. While radiation may not hurt your eyes, you are fixing your eyes on a powerful light source for a few inches to a few inches longer, and that may be the case. Eye strain. Your eyes may become dry, irritated, dull or even have a headache when you finally look at the hour screens. Blue light blocking technology helps reduce that stress by making the light more soothing and less bright.

The AAO recommends the 20-20-20 rule, where every 20 minutes you should look at something 20 feet away for 20 seconds to rest your eyes. It’s a good habit to get inside, but it’s not always realistic, and it’s not the only thing you can do to help your eyes.

I have occasional mild-sensitive headaches, and I have found that tinted lenses help reduce them. For that, blue light blocking glasses are very useful. They warm the light, blocking your eyes a little from resting. They can reduce eye strain, which is more than just a commitment to stop the blue light.

So you can really be served well by some blue block blocking glasses. There are a few other options to consider. With that in mind, read on for products that can (and can’t) reduce screen tension in your eyes.
