Do cheap sunglasses protect eyes?

In the previous article, we discussed “Where is it more cost-effective to wholesale sunglasses?”. In this article, let’s talk about “Do cheap sunglasses protect eyes?”.

Sunglasses are really useful things. Even people with average looks will immediately improve their temperament after wearing sunglasses. However, there are too many styles and brands of sunglasses, ranging from dozens of dollars to hundreds of dollars. What is the difference? Do cheap sunglasses protect eyes?

Ultraviolet Light And Strong Light

No matter how much the sunglasses are, they all have the function of dimming the outside light. However, dimming the light does not mean blocking ultraviolet rays. Some sunglasses can also reduce the degree of glare, but they cannot block ultraviolet rays. Ultraviolet light refers to the sun's rays with a wavelength between 200nm and 380nm, so any lens that can prevent light with wavelengths above 380nm can effectively prevent ultraviolet rays. At present, one of the most common indicators is 'UV400'. If the sunglasses have the mark 'UV400', they can have the function of UV protection.

Permanent Eye Injury

Wearing sunglasses, the light becomes darker, so people’s pupils will increase. However, if your sunglasses can’t block ultraviolet rays, it means that a lot of ultraviolet rays are ingested into the enlarged pupils. In this way, the eyes even hurt more than not wearing them. Moreover, the damage of ultraviolet rays to the eyes is cumulative and irreversible.

Damage To Eyesight

This is mainly a matter of workmanship. General glasses, whether it is sunglasses or other glasses, have a reasonable design of optical indicators, including sphericity, prism, etc. If the design is unreasonable, it is easy to make objects deformed and cause double eye fatigue and vision loss in the long term.

The Importance Of Lens

When choosing sunglasses, the lens is very important. It is not enough to darken the sun. It must also block ultraviolet rays, infrared rays, and blue light that are uncomfortable to the eyes. Otherwise, although the sun can be weakened, the harmful light cannot be blocked. Sometimes, because the light is dimmed and the pupils are dilated, more harmful rays will enter the eyes resulting in more damage to the eyes. We have chosen sunglasses with better UV protection lenses. The quality is different, and of course, the price will be different.
