Why wearing sunglasses is good for your eyes?/Sunglasses: dark color or light color?

Seven reasons to wear sunglasses

1. When the eyes are exposed to strong sunlight, the cornea absorbs most of the ultraviolet rays, which can cause keratitis and conjunctivitis.

2. If UV exposure to the eyes accumulates over a long period of time, it can cause vitreous fibrosis, leading to permanent vision damage. 3. If UV exposure to the eyes accumulates over a long period of time, UV rays can penetrate the cornea and “touch” the lens and retina, which can cause macular degeneration and permanent vision damage.

4. Excessive exposure to UV light can also cause subconjunctival degeneration to grow.

5. Prolonged over-exposure to ultraviolet rays can also lead to cataracts because ultraviolet rays stimulate the free radicals and ketone bodies in the eye to flourish, making the crystals cloudy and forming cataracts.

6. Middle-aged and old people who originally have only slight cataracts will be aggravated by cataracts if they do not take eye protection measures when they go out in the summer heat.

7. If ultraviolet radiation on the eyes accumulates over a long period of time, it will also cause facial crack spots.

The weather is getting hotter and hotter, the sun is getting more and more fierce and harsh, how to choose dark and light color sunglasses? I tell you, you should use different sunglasses for different occasions, and it is better for a person to have more pairs of glasses!

　　Dark color sunglasses - outdoor

　　Representative colors: teal, dark gray, dark green

　　When traveling or playing outdoors, usually a sunny environment, it is recommended to choose sunglasses with large dark lenses, such as teal, dark gray, dark green and so on. These colors can effectively reduce the irritation of sunlight to the eyes.

　　Bright color sunglasses - indoor and night

　　Representative colors: red, orange, yellow

　　Red, orange and yellow belong to light-enhancing colors, which cannot be worn in sunny environments because they will make the sunlight more harsh, but are suitable to be worn when driving at night, watching movies in the cinema or attending parties because wearing them in darker nights or gloomy interiors not only won't make the outside world's colors darker, but will also play a role in making the vision clearer and brighter.

　　Polarized lenses - when driving

　　Polarized lenses can reduce the irritation of light to the human eye, reduce the impact of oncoming headlight beams or tail lights, can filter harmful stray light, effectively reduce the discomfort of the eyes to the light, so that the field of vision is clearer.
