1 in 3 people have dry eye
The corneal surface of the eyeball is covered with a tear film. The tear film is divided into a lipid layer, an aqueous layer and a mucin layer. The three layers perform their respective functions to protect the tears from direct contact with the air and reduce evaporation, thereby playing a role in Keep our cornea and conjunctiva moist. When any layer of the problem occurs, causing eye discomfort, it is dry eye.
It is reported that the incidence of dry eye is about 30% worldwide. Dry eyes, foreign body sensation, redness, and even difficulty seeing are typical symptoms of dry eye.
Why stare at the electronic screen for a long time
Prone to dry eye?
Normally, you need to blink 15-20 times per minute. Blinking can distribute tears evenly on the cornea and conjunctiva to keep the cornea and conjunctiva moist. When the eyes are fixed on the electronic screen, the blinking frequency will drop significantly, which induces dry eye syndrome.

The one-minute blink test is to test the number of blinks of a person with normal eye function in one minute under different conditions.
The test is initiated without the subject’s knowledge. In a 1-minute period, how many times did the subjects blink while chatting, playing with mobile phones, looking at tablets and desktop computers?

Is the legendary “eye protector” reliable?
Dry eyes, drop the net red eye drops and it will be fine. ❌
The ingredients of some net red eye drops are unknown, and long-term repeated use may lead to aggravation of dry eye symptoms, so net red eye drops should be used with caution.
Regularly wash your glasses with eye wash to be healthier. ❌
The eyes have a “self-cleaning” function. Every time you blink, the tears will wash the surface of the eyeball, and you don’t need to use eyewash to clean your eyes.
The electronic screen is changed to green to protect the eyes. ❌
The green light is soft and can reduce eye irritation. But it does not relieve dry eye syndrome.
