In the previous article, we discussed “What color sunglasses lenses are best for fishing?”. In this article, let’s talk about “Can cheap sunglasses harm my eyes?”.
Why can't you wear poor-quality sunglasses?
The pupil becomes larger after being irradiated by light, and the incident light will directly enter the pupil and reach the retina after wearing poor-quality sunglasses. When you are not wearing sunglasses, the pupils will automatically become smaller when the sun comes in, so as to achieve the purpose of protecting your eyes. However, wearing poor-quality sunglasses will expand the path for ultraviolet rays to enter, resulting in an increase in the number of ultraviolet rays. Therefore, if you wear inferior sunglasses, the harm is even greater than not wearing sunglasses.
What are the hazards of cheap and inferior sunglasses?
All sunglasses have the function of dimming the outside light, but dimming the light does not mean blocking ultraviolet rays. Some sunglasses can also reduce the degree of glare, but can not block ultraviolet rays. Generally, the more expensive sunglasses can guarantee its function and quality, but the cheaper sunglasses cannot.(https://www.koalaeye.com/blogs/our-stories)
Wearing low-quality sunglasses can cause damage to your eyes. Wear sunglasses, the light becomes dim, so people’s pupils will increase. Because inferior sunglasses can't block ultraviolet rays, it means that a large amount of ultraviolet rays are ingested into the enlarged pupils, which is very harmful to the eyes. Moreover, the damage of ultraviolet rays to the eyes is cumulative and irreversible.
Inferior sunglasses hurt eyesight. General glasses, whether it is sunglasses or other glasses, have a reasonable design of optical indicators, including sphericity, prism and so on. If the design is unreasonable, it is easy to see the object deformed, causing double fatigue of the eyes, and long-term vision will be reduced. Good sunglasses are functionally capable of preventing ultraviolet rays, reducing visual distortion optically to protect eyesight, and being comfortable and strong to wear. However, cheaper sunglasses do not guarantee their functions and are easy to damage the eyes.
