Contact lenses are usually an alternate solution to eyeglasses. The kind of lens that you use determines the care you should take of it. Least care is enough for an extended-disposable-wear soft lens and extensive care is needed for a traditional soft lens. Lenses, if not cared for properly, can lead to vision-threatening complications.
Millions of people around the world use contact glasses safely. There is, however, eye infection that can be caused by the lenses and the following are the factors that result in an infection:
- Extended-wear lens usage
- Tear exchange reduced under the lens
- Environmental factors
- Poor hygiene
The choice of lens
The infection risk varies depending on the kind of contact glasses you use. Daily disposable, single-use lenses are safe as any germs that the lens has are not transferred to the eyes as they are changed daily. Rigid gas permeable lenses are the safest as they allow permeation of oxygen at the front surface, which is necessary for eye health.
Some steps in caring and cleaning your lenses:
Your hands must be washed with soap and water and dried and rinsed with a towel before you handle contact glasses. Also, keep your lenses from the contact with water. For example, before swimming or getting into a hot water tub.
The lenses should not be washed with or stored in water. Only use the lens cleaning solution to clean your glass, and while cleaning with your fingers, rub your contact lenses, and before soaking them, rinse them with a solution.
Your contact glasses case must always be kept clean and must be replaced at least once every 3 months. These cases can be a source of infection and contamination, so never use damaged or cracked lens cases.
Do not use rewetting drops or saline solution to disinfect your lenses. More importantly, saliva from your mouth must never be used to wet your contact lenses, as it is not sterile. Replace and wear your contact lens as per the eye care professional's prescription.
Handling the contact lens solution
The solution must never be transferred into smaller travel-size cases, and if the solution is old, must not be reused. Make sure the tip of your solution bottle does not come in touch with anything. When the solution is not used for a long time, always keep the solution container tightly closed to prevent it from getting contaminated.
