Contact lenses are lenses that are used on the surface of the cornea of the eye to correct various disorders of eye acuity, such as nearsightedness, farsightedness, astigmatism (cylinders), and farsightedness related to aging.
Contact lenses consist of two types, namely soft lenses and hard lenses. Soft contact lenses are the most popular type throughout the world because these lenses are able to adjust to the shape of the eye, are more comfortable and can stay firmly in place. Therefore, soft contact lenses become the main choice for those of you who have an active lifestyle.
The use of contact lenses is increasingly popular in this day and age. Disorders and discomforts that occur due to wearing glasses such as easily separated, the handle feels heavy, leaving marks on the top of the nose, can not be used in all kinds of activities for example when exercising, everything can be overcome by wearing contact lenses. In fact, contact lenses are increasingly being used for non-medical purposes such as cosmetics and aesthetics.
Various reasons can underlie a person’s goal to use contact lenses. Whatever it is, it doesn’t matter as long as you use contact lenses according to the rules. One of the rules most often ignored by users is: lazy to take off contact lenses and keep wearing them during times that are not recommended.
One time that is not recommended is when resting at night. Contact lens wearers who can last more than one day, often removing and replacing contact lenses is a hassle. But you still have to obey it because letting the lens carry during sleep will increase your risk of an infection called Keratitis.
Don’t Remove Contact Lenses? This is the danger!
Keratitis is an inflammatory condition on the cornea, the outermost area of the eyeball (where the contact lens is positioned). This clear layer is the part that plays an important role in the sharpness of vision. Keratitis is often suffered by contact lens users who are negligent in lens care, which is rarely clean contact lenses with disinfectant fluid, so contact lenses are “seized” by germs. Germs that can cause keratitis in the form of bacteria, viruses, fungi, and parasites (especially parasitic types of tapioca). The symptoms it causes are as follows:
- Redness of the eyes
- Eye pain
- Vision becomes blurred
- Watery eyes continuously
- Lots of dirt in the eyes
- Feeling dazzled
- Feels like something is up when blinking
When someone does not routinely remove the contact lenses they use, the frequency of cleaning contact lenses is greatly reduced so that the risk of keratitis is greatly increased. Keratitis is a form of severe infection that can cause serious complications that permanently damage vision.
Therefore, practice the use of contact lenses that are good and right. Here are the tips:
- Before installing and removing it, first make sure your hands are clean.
- Also use a special contact lens washing liquid (do not use ordinary tap water).
- If your contact lenses are only used for 1 day, then do not extend their use.
- Don’t forget to remove contact lenses before you sleep, shower, swim, etc.
In addition to an increased risk of infection, in certain people who are prone to / have experienced dry eye conditions, wearing contact lenses for too long can also aggravate symptoms of dryness in the eye. Contact lenses can play a role in the event of dry eye. Nearly 50% of contact lens users complain of dryness of the eyes. Therefore, for patients suffering from dry eye syndrome, contact lenses are not really the best solution to correct refractive abnormalities.
Contact lenses, like the human eye, need adequate hydration (humidity) all the time to keep it functioning optimally. Lack of body fluids, room heat, exposure to smoke from various sources, wind, can cause contact lenses to dry up and worsen the condition of the eyes that are already vulnerable. Therefore for patients with dry eyes who still want to use contact lenses, it is not recommended to use it for too long. Remove contact lenses when not really needed, especially if dry eye symptoms such as redness, burning, and heat in the eyes have appeared. In this condition, the use of artificial tears and other forms of special eye lubricants can help relieve these symptoms.
