In the hot summer, be careful about dry and sore eyes!

What does your summer look like? Watermelon! Popsicles! Air conditioning! The temperature is gradually rising and the weather is getting drier. Do you feel dry eyes and foreign body sensation when you are tired, and are afraid of strong sunlight? Then you should worry about dry eyes!

What are the factors that trigger dry eyes in summer?

Staying in an air-conditioned room for a long time: Most areas start using air conditioners after summer. However, while the air conditioner delivers cold air, it also removes moisture from the room. At the same time, when the air conditioner is turned on, the doors and windows are closed, and the indoor air is not circulated, which is more likely to induce dry eyes.

Less outdoor exercise: In the hot summer, most people would rather stay indoors than do outdoor exercise. Less outdoor exercise also means more time spent using electronic products. When staring at a computer or mobile phone screen for a long time, the number of blinks decreases, and the eyeballs are exposed to the air for a long time, causing moisture to evaporate too quickly, resulting in dry eyes and discomfort, which can easily induce and aggravate dry eye syndrome.

Wearing contact lenses for a long time: Summer is the peak travel season, and many people choose to wear contact lenses when traveling. However, wearing contact lenses for a long time will aggravate the evaporation of tears and cause related dry eye symptoms.

Unbalanced diet and lack of vitamin A: In hot summer, appetite decreases and the diet is unbalanced. If the body lacks vitamin A, dry eyes are likely to occur. Continuous vitamin A deficiency may also cause thickening or softening of the conjunctiva, resulting in decreased vision.

How to prevent dry eyes in summer?

Blink more: Generally, we blink about 20 times per minute. When using electronic products, we blink less frequently due to excessive concentration, resulting in insufficient tear moisture in the eyes. Conscious blinking can relieve dry eyes to a certain extent.

Pay attention to eye hygiene: It is easy to sweat in summer, so it is recommended to wash your hands frequently and do not rub your eyes with your hands.

Eat more foods rich in vitamins: Eat more fresh fruits and vegetables, and increase the intake of vitamins A, B1, C, and E. Vitamins are the main nutrients for maintaining the normal metabolism of human epithelial tissue, which can maintain the normal metabolism of the cornea and improve the ability to see in dim light.

Shorten the time of wearing contact lenses: It is recommended to wear contact lenses for no more than 8 hours a day, and wear contact lenses and frame glasses alternately.
