What is blue light and how can it harm you?
There are many types of light rays that are harmful. You have certainly heard of ultraviolet rays, produced by the sun at its most intense times, and all the negative effects they are capable of generating. Blue light is yet another part of this group.
Electronic devices, mainly computers, smartphones, televisions and LED lamps, emit blue light. Therefore, most people are in contact with it. The brighter the screen, the higher the emission.
There are two major problems with blue light: First, it can damage human eyes, causing eye fatigue and damage to the lens and retina, leading to muscle degeneration in the region. Second, it blocks the production of melatonin, the hormone that regulates our sleep.
Have you noticed that your sleep worsens in quality after using an electronic device for a long time before going to sleep? That’s exactly why.

When should you use blue light blocking glasses?
You should look for blue light blocking glasses especially if you are a person who spends a lot of time in contact with electronic devices, especially computer screens, smartphones or televisions.
Purchasing glasses is recommended for those who spend hours in contact with electronic screens.
Each of these screens emits large amounts of blue light and, therefore, it is necessary to block. If you spend hours a day fiddling with this equipment, work in contact with them or have no way to make a reduction, purchasing the glasses is the best solution.
The use of blue light blocking glasses is independent of problems such as myopia or astigmatism and has no influence, either positive or negative, on their wearers. It relates only to excessive contact with electronic screens.
Blue light blocking glasses or with an adaptive lens?
A possibility sought by many people is glasses with an adaptable lens, also known as clip on, which allows constant changes according to the situation.
In an adaptable glasses, you can put the blue light blocking lens when you are in front of a screen and then exchange it for an ultraviolet blocker when you leave towards the sun. This versatility is the main advantage.
However, glasses with adaptable lenses do not usually have much quality in any of their options. They serve only as preliminary blockers, far from having the same effects as models really specialized in a given protection.
We recommend adaptable glasses only if you don’t spend that much time in front of screens or the sun and want to have light protection while saving money. Otherwise, stick with separate models, one for protection from blue light, the other against ultraviolet rays.
In the table below, you can find a comparison between the two types:

More than just vision accessories, glasses have become fashionable accessories. And, of course, this also applies to blue light blockers.
If you wear glasses at work or with family members, you may want it to be beautiful and match your face. Therefore, evaluating the design is very important. Choose a format that pleases you, does well for your self-esteem and guarantees your mental well-being.

The color of the lens can also influence the efficiency of protection.
In addition to these same aesthetic reasons, the color of the lens can also help with the efficiency of protection. Some darker colors, especially orange, are very good for a more complete filter of blue light.
For aesthetic reasons, some people would never wear glasses with an orange or red lens. They can choose a neutral color and still have good protection. But, for those who like it, this possibility combines the useful with the pleasant!
The most modern blue light blocking glasses have some other important functions. We have already talked about the rod adjustments, which allow simultaneous use with prescription glasses or even ultraviolet light blockers. But not only that.
There are models, designed mainly for gamers, that are able to enhance colors and improve the graphics conditions of the games. They are among the most expensive blocking glasses, but they can be very useful for that specific audience.
Sunblock-blocking glasses are not meant to be used all the time. Therefore, they spend a lot of time stored and, in order to have a high durability, they need an efficient way of storage.
Some models offer very good boxes for storage and transportation, with zipper or button. Prefer those that have this kind of facility, as this can prevent your glasses from breaking, scratching or being damaged shortly after purchase
