It is not recommended to wear contact lenses and then swimming goggles when swimming. The water in the pool contains a large number of pathogenic microorganisms, and if you wear contact lenses, they may cause microorganisms to attach to your eyes, leading to various eye diseases, such as conjunctivitis and keratitis. On the other hand, wearing contact lenses will lead to a decrease in the oxygen permeability of the eye, which in turn will cause corneal hypoxia, thus easily causing dry eye disease. In addition, swimming itself may lead to conjunctival or corneal infections, and if you wear contact lenses while swimming, you will increase the chance of these diseases occurring. In order to get a better swimming experience, you can choose swimming goggles with degrees, which are clean and hygienic at the same time. If you have red, stinging eyes after swimming, seek medical attention for physical examination and conjunctival secretion tests and other tests to clarify the cause and treat the cause. For example, for bacterial infections, topical anti-infective medications can be applied, including levofloxacin eye drops and tobramycin eye drops. Eye diseases caused by viral infections can be treated with antiviral eye drops, such as ganciclovir eye gel and acyclovir eye drops, under the guidance of a doctor.
