Contact lenses are visual aids worn directly on the eye. Just like eyeglasses, contact lenses help to correct vision. When used with care and proper supervision, contact lenses are a safe and effective way to correct vision and may be a good alternative to eyeglasses depending on certain factors.
Contact lenses can also be cosmetic, that is worn for beautification purposes only. This type of contact lenses are often coloured and it can enhance or completely change the hue of the eyes. All contact lenses, regardless of the type or purpose are visual aids which require a prescription.
Because side effects can occur, some of which can be serious, it is very important that you see an eye doctor if you are considering wearing contacts. Although contact lenses may be a good alternative to eyeglasses, not everybody can wear it. If you have frequent eye infections, dry eyes or you live in a dusty environment, contacts may not be suitable for you.
When your eye doctor says it’s OK for you to get contact lenses, here are some of the precautions you must take in wearing your contacts:
- Wash your hands with soap and water before handling them
- Clean them daily. Never use home-cleaning solutions to clean your lenses as this may lead to serious eye infection
- Never, under any circumstances reuse your contact lens solution
- Do not share them with anyone else
- Dispose them at the interval prescribed by your eye doctor
If you experience any of these symptoms, remove your contacts immediately and see your eye doctor:
- Blurry vision
- Scratchy eye
- Sensitivity to light
- Discharge from the eye
- Pain in the eye
