Are sunglasses harmful to eyes?

People should understand that strong light stimulation to the eyes has become a disease that seriously troubles people's lives, and most treatments so far are not perfect. Strong light stimulation to the eyes is caused by not paying attention to eye health, and lifestyle and diet must be strictly controlled. Strong light stimulation to the eyes causes anxiety in life and causes great damage to the eyes. If you want to get rid of strong light stimulation to your eyes, you should go to the ophthalmology department for relevant examinations and treatment as soon as possible. Follow me to see, are sunglasses harmful to the eyes?

1. Disadvantages of wearing sunglasses for a long time

When ordinary people wear sunglasses, their eyes' perception of external objects will be very different from usual, which is specifically manifested in the following two aspects: First, the contrast of objects observed by the eyes is very different. After wearing sunglasses, many people will feel that they cannot see as clearly as without them. In order to see more clearly, they will naturally look at objects harder. Over time, the degree of eye fatigue will increase. Ophthalmologists believe that tinted sunglasses will put people's eyes in relatively dim light, and people's pupils will subconsciously dilate. If people's eyes are in this state for a long time, even if their original vision is good, it will deteriorate in the future. However, this degradation process is relatively slow and difficult to detect in the short term, so it is easier for people to take it lightly.

Secondly, although the ultraviolet rays in the sun can be partially blocked by the lenses of sunglasses, medical research has shown that ultraviolet rays are first absorbed by the lenses before being dissipated. Therefore, after wearing sunglasses, a person's pupils will be in a state of flickering light and dark, and size. This is also the reason why people feel uncomfortable after putting on sunglasses.

Dr. Edward, who has run an ophthalmology clinic in New York for nearly 20 years, said that many of his patients have very good eyesight but suddenly feel eye discomfort for a while. After checking, he found that it was all caused by the sunglasses. These patients with mild eye problems usually have the habit of wearing sunglasses because they need to drive themselves. They rarely take off their sunglasses after getting out of the car and entering the room. Some people even wear them for more than 8 hours continuously, which causes harm to their eye health.

2. Wearing sunglasses for a long time can cause "sunglasses syndrome"

Mr. Du said that wearing sunglasses has become a habit for him and he must wear sunglasses whenever the sun is out. Experts say that 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 impair vision. Moreover, sunglasses should not be worn for too long. After wearing sunglasses continuously for 1-2 weeks, symptoms such as numbness of the skin and dull perception will appear in the eye sockets or between the cheeks; there will be discomfort in the nose when breathing, just like having a cold; some people will also feel that there are small insects crawling on their faces and their eyes are sore and swollen. These are all manifestations of "sunglasses syndrome".

3. Poor quality sunglasses are the most harmful to your eyes

It is recommended that people should be cautious when choosing sunglasses and not buy low-quality sunglasses for the sake of cheapness. 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 with glaucoma, color blindness, night blindness and retinitis should stay away from sunglasses. Middle-aged and elderly people with deteriorating vision and preschool children with fragile optic nerves should not wear sunglasses at any time.
