What Are Contact Lenses?

Contact lenses are medical devices made from special materials such as hydrogel or silicone hydrogel, which are flexible and transparent. These materials allow the lenses to sit comfortably on the cornea without causing discomfort.

They are used to correct vision problems such as:

Nearsightedness
Farsightedness
Astigmatism

In addition, colored contact lenses can enhance eye appearance, helping users feel more confident in their daily activities.

Types of Contact Lenses

There are three main types of contact lenses, categorized by material and function:

Rigid Contact Lenses

Rigid lenses are made from durable hard plastic and provide sharp vision. Modern versions, known as RGP (Rigid Gas Permeable) lenses, allow some oxygen to pass through, making them more comfortable for longer wear.

They are suitable for:

Complex vision problems
Irregular corneas
Severe dry eyes

Soft Contact Lenses

Soft lenses are made from flexible materials such as hydrogel or silicone hydrogel, allowing high oxygen permeability.

They are:

Comfortable to wear
The most popular choice
Suitable for daily use

Available types include:

Daily lenses
Weekly lenses
Monthly lenses
Extended-wear lenses

Hybrid Contact Lenses

Hybrid lenses combine the benefits of both types:

A rigid center for clear vision
A soft outer ring for comfort

They are ideal for users who need precise vision correction with added comfort.

How to Wear Contact Lenses

Wearing contact lenses is simple but requires proper care:

Wash your hands thoroughly and dry them completely
Clean the lens using contact lens solution
Place the lens on your fingertip
- Correct shape: bowl-shaped
- Inside-out lens: edges flare outward
Use your fingers to gently hold your eyelids open
Place the lens onto your cornea
Blink slowly to adjust

If you feel discomfort or blurred vision, remove, clean, and reinsert the lens.

How to Care for Monthly Contact Lenses

Proper care ensures safety and lens longevity:

Clean lenses after every use
Store in a clean case with fresh solution
Replace solution regularly (do not reuse old solution)
Replace lenses according to schedule (monthly lenses = every 1 month)
Avoid contact with water (e.g., swimming or tap water)

FAQs

Q: Can I sleep with contact lenses?

A: Most contact lenses are not designed for overnight wear. Doing so may increase the risk of infection. Only use lenses specifically designed for extended wear.

Q: Can contact lenses get lost behind the eye?

A: No. The conjunctiva prevents lenses from moving behind the eye. If displaced, lenses are usually trapped under the eyelid.
