Contact lenses are a great alternative to prescription glasses. Whether you’re active, style-conscious, or simply want a glasses-free look, contact lenses can offer comfort and convenience—when used properly. However, it’s important to know the types, benefits, risks, and care tips before switching.
What Are Contact Lenses?
Contact lenses are small, thin lenses placed directly on the eye’s surface to correct vision or enhance eye appearance. They are made of materials like silicone hydrogel, which allows oxygen to pass through, keeping your eyes healthy and reducing the risk of complications.
Contact lenses can correct various vision issues such as:
-
Nearsightedness
-
Farsightedness
-
Astigmatism
-
Presbyopia
Types of Contact Lenses
Soft Contact Lenses
Made of flexible plastic, they are the most commonly used type due to their comfort. Types include:
-
Daily wear lenses – removed, cleaned, and stored daily.
-
Extended wear lenses – worn overnight or longer, but carry a higher infection risk and must be used as prescribed.
Rigid Gas Permeable Lenses (RGP)
These are made of firm, oxygen-permeable material. They offer clearer vision, especially for astigmatism, and last longer than soft lenses.
How to Care for Your Contact Lenses
Proper hygiene is essential to avoid infections and discomfort. Follow these steps:
-
Wash your hands thoroughly before touching lenses.
-
Use the rub-and-rinse method with lens solution.
-
Store lenses in a clean case and replace the case every 2–3 months.
-
Never use tap water to clean your lenses.
-
Replace lenses according to your optometrist’s instructions.
Common Complications from Contact Lens Use
While contact lenses are safe when used correctly, improper care can lead to:
-
Dry eyes – lenses may block tear distribution.
-
Oxygen blockage – can reduce oxygen supply to the cornea.
-
Corneal abrasion – caused by improper fit or poor handling.
-
Red eyes and conjunctivitis – due to bacterial or viral buildup.
When You Should Not Wear Contact Lenses
Avoid using contact lenses if:
-
You have dry eye syndrome
-
You work in harsh or dusty environments
-
You have existing eye infections
-
You suffer frequent allergic reactions
Choosing the Right Contact Lenses
During a contact lens consultation at SpecSMART Eye Clinic Ikeja, your optometrist will measure:
-
Lens power – this differs from your glasses prescription.
-
Diameter – determined via a keratometry test.
-
Curvature – based on the shape of your cornea.
Wearing an incorrect prescription can lead to discomfort, redness, blurred vision, or corneal injury. Always consult your eye care provider first.
