How to properly protect your eyes from the sun in summer

　　UV pair Eye what harm

　　Experts explain that scientific research continues to emphasize that the damage caused by ultraviolet rays is gradual and permanent. Eyeballs related to UV rays disease There are many, and the common ones from the outside to the inside include the following:

　　Eyelids: In addition to producing pigmentation and sun spots, it also increases the risk of skin The chance of cancer, such as eyelid skin cancer and basal cell carcinoma.

　　Conjunctiva: Causes degeneration of the conjunctival tissue, resulting in eye cracks or wing-like tags. Taiwan is located in the subtropical zone. A common pterygoid is in the conjunctiva of the white of the eye, close to the edge of the black eyeball, forming a triangular vascular fibrous membrane. It not only affects the appearance, but also may cause visual impairment, requiring surgical treatment, but it is also prone to recurrence.

　　Crystal: Accelerate the turbidity of the crystal and improve premature birth Cataracts eventually require surgery.

　　Retina: Increases the risk of macular degeneration and potentially increases the risk of age-related macular degeneration, both of which may affect central vision.

　　Typically, the longer you spend outdoors, the more intense ultraviolet radiation your eyes and skin are exposed to, and changes in the environment, especially damage to the ozone layer, also make your eyes more susceptible to damage. You should be especially careful in spring and summer when the sun is relatively strong, that is, between 10 a.m. and 4 p.m. during the day.

　　How to protect your eyes from the sun in summer

　　Ultraviolet rays are so scary, how to prevent them? Experts suggest that reducing sun exposure and proper eye protection are two major principles to avoid UV damage to the eyes. General precautions include:

　　1. Don’t look directly at the sun. Eyes are relatively fragile organs. Looking directly at the sun, even if you squint your eyes and look directly at the sun for a short time, may cause temporary dark shadows in front of your eyes. Staring directly at the sun for a long time may damage the retina.

　　2. Avoid staying outdoors for long periods of time during peak hours of ultraviolet radiation to reduce excessive sun exposure. The time of excessive ultraviolet rays generally refers to 11 am to 2 pm.

　　3. When doing outdoor activities, pay attention to the ultraviolet damage caused by reflected light from water surfaces, beaches, road surfaces, etc.

　　4. When going out for activities or driving in the bright sun, you should wear ultraviolet protective lenses that can protect your eyes from UVA and UVB. For sunglasses, according to optical principles, the lens colors are brown and dark green. People who already wear glasses can go to an eyeglass store to test with a UV blocking meter to confirm whether their lenses have the function of blocking UV rays.

　　Finally, experts also mentioned that children's eyeballs are more fragile and they stay outdoors for a relatively longer time, so ultraviolet protection is more important, especially for children who receive myopia dilating agent treatment. Their pupils are enlarged and they receive more ultraviolet rays. Don't forget to prepare hats and sunglasses for them to ensure that children's eyes are bright. healthy。

　　Warm reminder: Be careful about wearing sunglasses in summer

　　I need to remind everyone here that not all colored lenses are called sunglasses. Sunglasses should have an anti-UV label. The anti-UV coefficient must be above 400 to be enough to protect your eyes. If you choose low-quality sunglasses that do not block ultraviolet rays, it is more likely to cause eye damage. Because a person's pupils will dilate after wearing such sunglasses, ultraviolet rays will enter the eyes more easily than when not wearing sunglasses, causing eye damage.
