Essential Guide to Contact Lens Usage and Selection

Important facts about contact lenses before starting use
Contact lenses are thin, curved optical devices designed to improve vision and sit directly on the eye surface. Usually clear, some have slight coloring for easier handling. If you want to avoid wearing glasses, contact lenses can be a practical solution. Keep these key points in mind when choosing your lenses.

What types of contact lenses are available?
Contact lenses are categorized into five main types based on their design:

Rigid Gas-Permeable Lenses: Introduced in the 1940s, made from polymethyl methacrylate, these lenses initially had oxygen transmission issues. The 1970s saw improvements with rigid permeable materials. They are lightweight and easy to wear.

Soft Contact Lenses: Developed in the 1970s from hydroxyethyl methacrylate, these water-absorbing lenses provide a snug fit and enhanced comfort, representing a significant advancement in lens technology.

Disposable Contact Lenses: Popular since the late 1980s, these soft lenses offer convenience. They are designed for specific periods—weekly, monthly, or quarterly—with options for daily replacement.

Silicone Hydrogel Lenses: Composed of silicone-based materials, these lenses permit better oxygen flow to the eye, supporting eye health. They are moist and resistant to drying out, reducing discomfort.

Scleral Lenses: Using advanced computer-aided design, these large lenses provide high comfort, especially for complex prescriptions. They cover more of the eye surface and are favored by users with special correction needs.

How long can contact lenses be worn?

The wear time varies by lens type; always follow your optometrist's advice.

Most lenses can be worn up to 16 hours daily safely.

Avoid overnight wear unless explicitly advised.

New users should increase wear time gradually to prevent discomfort.

Are contact lenses safe?

When used properly, they are generally safe, but over-wearing can damage your eyes.

Consult an eye specialist before starting to wear lenses.

Follow prescribed schedules to reduce risks.

Opt for high-quality lenses for optimal safety and comfort.

Can I shower with contact lenses?

Remove lenses before showering to lower infection risk.
