Is it Necessary to Wear a Pair of Sunglasses in Summer?
Many fashion workers choose to add a cool pair of sunglasses to their wardrobe during the hot summer months.But many people wonder, do I need a pair of sunglasses during the summer?
Do you really need sunglasses?Normal eyes can adjust themselves to light.The main reason for wearing colored glasses is that the eyes feel uncomfortable and the eyes are damaged by long-term contact with strong sunlight."The ability to tolerate bright light varies from person to person.If you squint or cry a lot in the hot sun, you should wear sunglasses.""An ophthalmologist advised.Strong light is harmful to the eyes.A person's constant exposure to the hot sun can reduce his vision at night by half, so he should wear sunglasses if he is on a long walk or on the beach.
However, don't wear dark glasses all the time to show off alcohol or to hide your eye problem, unless your ophthalmologist has instructed you to wear them due to a medical condition.The publication of the Consumer Council of Hong Kong has warned that wearing sunglasses unnecessarily often will be addictive, and it will be very uncomfortable if you don't wear them during the day. Will cheap sunglasses damage your eyes?
The short answer is: probably.Cheap colored lenses are blown, not polished.Blown glass is bound to have some faults.
Substandard sunglasses are on sale everywhere.Retailers say the problems are too minor for the average person to notice.This argument is specious.When the problem is mild, the muscles of the eye can adapt more or less, and constant adaptation results in muscle and nerve fatigue.Of course, if you're just doing solarizing and your eyes aren't working, the problem won't be as serious.But to work outdoors, such as construction, reading, playing tennis, or driving long distances in the hot sun, your eyes need to move up and down, from near to far, and use the whole range of lenses, so it is difficult to adapt to a pair of poor quality lenses constantly.
