Eyes are very fragile parts of human organs, and contact lenses are in direct contact with eyeballs, so friends who wear contact lenses should take them seriously. The "sweat killer" should attract the attention of "invisible people", especially friends who like outdoor sports.
Sweat soaked in eyes can easily cover contact lenses. In addition, sweat itself contains bacteria, which will accelerate the growth of bacteria. Because sweat is not pure water, although the proportion of water in sweat is as high as 98%-99%, there are organic substances, such as urea and lactic acid, and inorganic substances, such as sodium chloride, calcium and magnesium. Although these discharged wastes only account for 1%-2% of sweat, they are invisible to the naked eye. Moreover, many kinds of bacteria are attached to sweat, which is easy to be used. Contact lenses directly contact the cornea and conjunctiva, which will prevent the cornea from getting oxygen from air and tears. Corneal hypoxia combined with bacterial growth can easily lead to corneal infection and corneal ulcer, with disastrous consequences.
