Is it necessary to bring a pair of sunglasses in summer?
Many fashion workers will choose to wear a pair of cool sunglasses in the hot summer to enhance their fashion. But many people wonder, do I usually need a pair of sunglasses in the summer? I don't need a concave shape. Today I will give you the answer
Are Sunglasses Really Necessary? A normal eye can adapt itself to light. The main reason for wearing tinted glasses is that the eyes are uncomfortable, and the eyes are damaged by long-term exposure to strong sunlight during work. "The ability to tolerate bright light varies from person to person. If you're squinting or crying a lot in the hot sun, you should wear sunglasses," advises an ophthalmologist. Strong light can damage the eyes. A person is often active in the hot sun, which will reduce his vision in half at night, so if you are walking long distances or on the beach, you should wear sunglasses.
However, don't always wear dark glasses just to show off or hide your eye disease, unless you have been ordered by your ophthalmologist to wear dark glasses due to a pathological condition. The Hong Kong Consumer Council has warned that wearing sunglasses unnecessarily will become addictive and will make you feel uncomfortable if you don't wear them during the day. Will cheap sunglasses damage your eyes?
The simplest answer is: very likely. Cheap tinted lenses are blown, not ground. Blown glass is bound to have such and such problems.
Substandard sunglasses are sold everywhere. Retailers say the bugs are so minor that the average person won't notice them. This statement is not true. When the problem is minor, the eye muscles can adapt to some extent, and the continuous adaptation will result in muscle and nerve fatigue. Of course, if you're just solarizing and the eyes don't have to work, the problem won't be so serious. However, to work outdoors, such as building, reading, playing tennis, and driving long distances in the hot sun, your eyes will have to move up and down, left and right, moving from near to far, using the entire range of the lens, so keep going. Getting used to a pair of poor quality lenses can be difficult.
