Is it bad to wear sunglasses all the time?

In the previous article, we discussed “Can cheap sunglasses hurt your eyes?”. In this article, let’s talk about “Is it bad to wear sunglasses all the time?”.

Sunglasses can block ultraviolet and infrared rays, while the color of the external environment does not change. In most cases, the main purpose of people wearing sunglasses is to prevent ultraviolet rays. However, some people think that since wearing sunglasses can prevent ultraviolet rays, the longer you wear them, the better the preventive effect should be. Therefore, they wear sunglasses almost every day when they go out and don’t take off sunglasses even indoors. So, long-term wearing sunglasses is really good for the eyes?

Disadvantages of wearing sunglasses for a long time

After people wear sunglasses, the perception of external objects in their eyes will be very different in normal times. First of all, the contrast of the object viewed by the eye is very different. After wearing sunglasses, many people will feel that they are not so clear when looking at things. In order to see more clearly, they naturally watch the object vigorously. However, if you look at it for a long time, the fatigue of your eyes will increase. Ophthalmologists believe that colored sunglasses make people's eyes in relatively dim light, and people's pupils will subconsciously dilate. If a person's eyes stay in this state for a long time, even if the original vision is good, it will degenerate in the future. However, this degradation process is relatively slow and difficult to be noticed in the short term, so it is easier to make people ignore this degradation.(https://www.koalaeye.com/collections/polarized-sunglasses)

In addition, although the ultraviolet rays in the sun can be partially blocked by the sunglasses lens. However, medical research has proved that ultraviolet rays are first absorbed by the lens before being emitted. Therefore, after wearing sunglasses, the pupils of the person will be in a state of flickering light and dark, large and small. That is the reason why people feel uncomfortable just after wearing sunglasses.

Dr. Edward, who has been operating an ophthalmology clinic in New York for nearly 20 years, said that many of his patients have very good eyesight, but suddenly they feel uncomfortable for a while. After inspection, he found that it was all caused by sunglasses. These minor ophthalmological patients, because they need to drive themselves, almost always have the habit of wearing sunglasses. However, they rarely take off their sunglasses after getting out of the car and entering the room. Some people even wear them continuously for more than 8 hours. These behaviors are harmful to eye health.

Long-term wearing sunglasses suffers from 'sunglasses syndrome'

Mr. Du claims that wearing sunglasses has become a habit. As long as there is the sun, he must wear sunglasses. According to experts, wearing sunglasses can indeed reduce the damage of ultraviolet rays to the eyes, but it should be noted that improper selection and wearing of sunglasses can harm the eyes and damage the eyesight. And the wearing time of sunglasses should not be too long. After long-term wearing sunglasses for 1-2 weeks, symptoms such as skin numbness and unconsciousness may appear in the eye sockets or between the cheeks. People will feel nasal discomfort when breathing, just like catching a cold. Some people also feel that there are small bugs crawling on their faces and their eyes are sore. These are all signs of 'sunglasses syndrome'.

Inferior sunglasses hurt the eyes most

Dr. Edward advises people to be cautious when choosing sunglasses and not to buy low-quality sunglasses for cheap. If you are in an environment where the ultraviolet rays are not too strong, you should take off your sunglasses in time. At the same time, to be on the safe side, people who suffer from glaucoma, color blindness, night blindness, and optic retinitis are best to stay away from sunglasses. Middle-aged and elderly people with degraded vision and preschool children with weak optic nerves should not wear sunglasses at any time.
