Summer is hot, sunglasses become a must-have for modern mass travel and outdoor activities (dressing a cool concave shape). This accessory, which has the most significant proportion on the face, erects a “shield” that protects the eyes from UV damage.
You don’t want to use the role of sunglasses. In addition to effectively filtering the ultraviolet rays in the sun, sunglasses also have the effect of delaying aging .
This is because in the windy weather or strong light, people will unconsciously squint their eyes, and the skin around the eyes is extremely fragile, and it is easy to climb wrinkles. Wearing sunglasses can protect the skin around the eyes from sunburn and prevent melanin.
Deadly light and its harm
Sunglasses protect your eyes from UV rays, infrared rays and visible light. Let’s take a look at the hazards of these lights.
Ultraviolet rays – can cause different degrees of damage to the eyelids, conjunctiva, cornea, lens, vitreous, retina, causing eyelid skin cancer, pterygium, cataract, macular degeneration, and so on.
Infrared – Infrared is a kind of heat radiation. Different wavelengths of infrared light can cause different damage to the eyes. Intense infrared rays can cause skin damage.
High-energy visible light, primarily blue light, passes through the cornea and lens and contacts the retina, causing incalculable damage to the eye.
Common misunderstandings and minefields
The choice of sunglasses is not as simple as we think, and there are many doorways. Wearing inappropriate sunglasses cannot only resist ultraviolet rays but also cause eye diseases such as cataracts and glaucoma. Let’s take a look at what are the pitfalls and minefields:
Children under 3 years old wear sunglasses. This period is a sensitive period of vision development of the baby. It is necessary to continuously receive stimulation and contact with clear images to stimulate visual development better. If you wear sunglasses frequently, it may affect the adjustment of visual function, resulting in visual problems such as weakness.
Wear dark sunglasses while driving. Dark sunglasses easily filter out bright objects, affecting the judgment of the size of the front room and the distance between the cars. In an emergency, the optic nerve is also delayed in image analysis, resulting in slow response and significantly increasing the likelihood of a hazard.
Some older adults with shallow anterior chamber structures and at risk of developing angle-closure glaucoma wear sunglasses.Therefore, ophthalmologists remind that patients with eye diseases such as glaucoma and night blindness should not wear sunglasses.
