How to prevent dry eye by wearing contact lenses?
According to the survey, about 30% of people who often wear contact lenses suffer from dry eye. Dry eye is the most common ocular surface disease, but long-term dryness can also cause eye damage, so it must be prevented as soon as possible.
Dry itching and foreign body sensation are typical manifestations of dry eye. Mild dry eye can lead to visual fatigue, while serious dry eye can lead to congestion, swelling and tears in the wind. At this time, the cornea has been damaged to a certain extent, if we do not pay more attention to health, it will turn into inflammation and infection.
In fact, there are many causes of dry eye. It is not very accurate to say that wearing contact lenses can cause dry eye. Long-term use of eyes, dry climate, dust weather and so on will make people unconsciously suffer from dry eye, but after wearing contact lenses, it will increase the demand for tear volume, so that the eyes are easier to dry. Therefore, if you already have dry eye, it is generally not recommended to try contact lenses again.
For people with less tear secretion, Suncast lenses may be a better choice, but at the same time, we should pay attention to water supplementation, and use artificial tear without preservatives when necessary. When wearing, take the initiative to increase the number of blinks, shut your eyes at intervals for a short rest. If a slight dryness is caused by wearing contact lenses regularly, the wearer can recover by himself after stopping wearing contact lenses for a period of time, without affecting the continued use of contact lenses. However, if there are serious dry eye symptoms, we must treat them in time.
In order to prevent dry eye, we should be vigilant against all kinds of bad eye habits, pay attention to the use of contact lenses, and control the wearing time reasonably. At the same time, regular ophthalmic examination should be carried out to strengthen eye care.
