Wearing the Wrong Sunglasses to Look Cool Can Hurt Your Eyes
The main function of sunglasses is to filter out ultraviolet rays. Excessive exposure to ultraviolet rays (UV) in sunlight can cause diseases such as cataracts, pterygium, eyelid skin cancer, and electric ophthalmia. Even if you wear a wide brimmed hat, it can only block 50% of the ultraviolet rays that reach the eyes, so you also need to wear sunglasses.
The glare of sunlight can make the eyes uncomfortable, affect the clarity of vision, and people will squint and shed tears. Wearing sunglasses will greatly increase comfort. In addition, sunglasses can also enhance dark adaptation. If people do not wear sunglasses and stay in bright sunlight for 2-3 hours, their adaptability to darker environments (such as tunnels) will decrease, leading to safety hazards.
1.What diseases can be easily induced by improper wearing of sunglasses
May cause visual fatigue
Poor quality sunglasses with a rough surface and uneven color tones can easily induce visual fatigue. Some people also wear sunglasses regardless of time and occasion, regardless of the intensity of the light, and even watch movies and TV. This increases the burden on the eyes, causing symptoms such as eye muscle dizziness and inability to see for a long time.
2.Can cause sunglasses syndrome
Sunglasses syndrome is more common among trendy young people who prefer to wear large frame sunglasses with wide edges, thick frames, and heavy weights. After wearing it continuously for 1-2 weeks, symptoms such as numbness in the eyes or between the cheeks, slow perception, and discomfort in the nose during breathing can appear, just like catching a cold. Some people feel like small insects crawling on their faces, numbness in their upper gums, discomfort in their front teeth, and sore eyes. This is because thick, wide edged, and heavy sunglasses often compress the infraorbital branch of the trigeminal nerve, leading to the above symptoms.
3.May cause retinal disorders
If you wear sunglasses without UV protection, it is more dangerous than not wearing sunglasses. Because the human body has an instinctive response to self-protection, when the eyes encounter strong light, the pupils will naturally shrink, reducing the amount of ultraviolet energy entering the eyes. Once you wear substandard dark sunglasses, it will cause the pupils to enlarge. In addition, the glasses do not have the function of isolating ultraviolet rays. At this time, the eyes are like opening the door wide, and the invading ultraviolet energy will greatly increase, causing damage to the lens and retina.
4.Can induce acute attacks of glaucoma
Because sunglasses reduce light intensity, they can cause pupil enlargement. If the lenses cannot prevent ultraviolet rays, more ultraviolet rays will enter the eyes, causing greater damage to the eyes. Regular brand sunglasses generally have this function, but it is difficult to say that some low-quality and inferior brands of sunglasses, so it is important not to seek cheap opportunities to buy some unconventional sunglasses.
At the same time, ultraviolet radiation is a key protection point for sunglasses due to its short wavelength and high energy. The protection against ultraviolet radiation is further divided into:
1) Short wavelength UV380 or below;
2) Long wavelength UV400 or below.
The protection below UV400 is more comprehensive, covering the protection of UV380. A high-end mirrorometer can perform quantitative testing on this function.
5.No abnormal distortion or deformation of the lens
The probability of this happening with sunglasses is higher than with regular glasses. There is specialized equipment available for testing, which is not available in regular eyewear stores. So if you feel dizzy immediately after wearing a pair of sunglasses, then don't buy them. The probability of this situation occurring in low-end sunglasses is higher.
