Essential Information to Know Before Trying Contact Lenses

Key facts about contact lenses before use
Contact lenses are slim, curved optical devices designed to correct vision and overlay the eye surface. Usually transparent, some lenses have light pigmentation for easier handling. If you prefer to avoid bulky glasses, switching to contact lenses can be a good choice. Keep the following points in mind when selecting your lenses.

What are the different kinds of contact lenses?
Contact lenses fall into five main categories based on their design:

Rigid Gas-Permeable Lenses: Introduced in the 1940s, made from polymethyl methacrylate, these lenses faced oxygen transmission issues. The 1970s saw an improvement with rigid permeable designs. They're lightweight and straightforward to wear.

Soft Contact Lenses: Developed in the 1970s from hydroxyethyl methacrylate, these water-absorbing lenses comfortably conform to the eye's surface, marking a technological milestone in lens comfort and flexibility.

Disposable Contact Lenses: Emerging in the late 1980s, these lenses are very soft and offer convenience. They are worn for a specific period—weekly, monthly, or quarterly—with daily options available.

Silicone Hydrogel Lenses: Made from silicone-based plastics, these allow higher oxygen flow, promoting eye health. They are wettable and resist drying, reducing discomfort and irritation.

Scleral Lenses: Advanced computer-aided design provides exceptional comfort for complex prescriptions. These large lenses cover a significant part of the eye and are highly popular among users needing specialized correction.

How long can contact lenses be worn?

The duration varies with the lens type; always follow your eye care professional's guidance.

Typically, lenses can be worn for up to 16 hours daily without issues.

Avoid wearing lenses overnight unless specified by your doctor.

New users should gradually increase wearing time to prevent discomfort.

Are contact lenses safe?

Generally safe when used correctly, but excessive wearing can harm your eyes.

Consult an eye care specialist before use.

Adhere strictly to prescribed schedules to prevent complications.

Choose high-quality lenses for better comfort and safety.

Can I shower with contact lenses?

Removing lenses before showering minimizes infection risk.
