1. The lighter the frame, the better.X
Wrong, the most important thing about the frame is stability. If the lens is too heavy and the frame is too light, it will not able to maintain the balance of wearing, not to mention that it will easily drop and cause the glasses to press on the bridge of the nose and leave marks.
2. As long as the power of the glasses does not increase, they can used forever.X
Wrong, the recommended service life of glasses is generally two years. After the time is up, you need to re-optometry to check whether there is any change in your own power and whether there are other problems. At the same time, observe whether the glasses are deformed, whether the lenses are scratched, etc., which is reasonable Replace the glasses.
3. The glasses frame type is not defined, and the large frame type can be worn at will. X
Wrong. Strictly speaking, it is not recommended for people with high myopia to wear large-frame glasses. Our pupil center needs to overlap with the optical center of the lens to ensure that the vision is clear and not distorted. The closer the part to the optical center is, the thinner it becomes. The optical center of large-frame glasses is generally in the upper position. As a result, the lens surrounding and especially the lower part will be too thick, which seriously affects the wearing experience.
4. Anti-blue light lenses can be chosen at will. X
Wrong. In today's market, there is no set of fully feasible standards for anti-blue light glasses, and the performance of some anti-blue light products does not actually meet the standard. Inferior products without other additional functions are fine, but they often have problems such as color cast and decreased clarity. Short-term wearing can cause increased visual fatigue, and long-term wearing can also cause damage to eyesight. At the same time, it should be noted that not all blue light needs to be shielded, and beware of "one size fits all" products.
5. Protect your eyes in summer √
This is correct. Ultraviolet rays will not only damage the skin, but also have a greater impact on our eyes. Long-term exposure to ultraviolet rays will make our eye lenses age and turbid, and increase the incidence of eye diseases such as retinal macula and cataracts. probability. Therefore, when going out in summer, a pair of sunglasses is quite necessary. Gray, brown, and green-gray lenses are the first choice. They have little effect on vision. At the same time, the spectral absorption is relatively uniform, which is very suitable for summer travel.
In addition, at the end of the article, I will give you a piece of knowledge: in fact, green does not play much role in protecting eyesight. Green can make people comfortable, in fact, it is only because of the feeling that the color itself brings, and it is more of a psychological effect. Besides greening the desk, the behavior of putting green plants on the table does not have much other effects. Office workers and student parties often feel visual fatigue because of long-term close vision. At this time, it is recommended to look far and massage, which can play a certain relaxing effect.
