Types of Contact Lenses
Different contact lenses serve various vision needs and come in a variety of materials and designs. Here’s an overview of the main types:
Soft Contact Lenses:
- Made from water-containing flexible materials that provide immediate comfort.
- Available in daily, bi-weekly, and monthly disposables.
- Popular for their ease of use and adaptability for active lifestyles.
Rigid Gas Permeable (RGP) Lenses:
- Durable, oxygen-permeable lenses that offer sharp, crisp vision.
- Often recommended for patients with specific needs, such as high astigmatism or irregular corneas.
Toric Lenses:
- Specially designed for people with astigmatism.
- These lenses provide clear, stable vision by aligning with the shape of the eye.
Multifocal/Bifocal Lenses:
- Ideal for presbyopia, allowing vision correction at multiple distances.
- Eliminates the need for reading glasses by providing both near and distance correction in a single lens.
Scleral Lenses:
- Larger in diameter, these lenses cover the cornea and rest on the sclera (white part) of the eye.
- Suitable for people with dry eyes or specific ocular conditions, such as keratoconus.
Colored Contact Lenses:
- Available in prescription and non-prescription forms to enhance or change eye color for cosmetic purposes.
Types of Contact Lens Solutions
Contact lens solutions are essential for cleaning, disinfecting, and maintaining lens comfort. Here’s a guide to the different solutions:
Multipurpose Solutions:
- Used for cleaning, disinfecting, and storing lenses, making them convenient for daily use with soft lenses.
- Combines all cleaning steps in a single solution.
Hydrogen Peroxide Solutions:
- A preservative-free solution that provides thorough cleaning and disinfection.
- Requires a special neutralizing case to ensure safe wear, as lenses cannot be worn directly after being in hydrogen peroxide.
Saline Solutions:
- Primarily used to rinse lenses but lacks disinfecting properties.
- Often used with hydrogen peroxide solutions as a final rinse after disinfection.
Daily Cleaning Solutions:
- Used to remove protein deposits and debris, especially for RGP lenses.
- Not a standalone disinfectant and must be paired with a disinfecting solution.
Enzymatic Cleaners:
- Used weekly to eliminate protein buildup on lenses, particularly for those wearing extended-wear lenses.
Caring for Contact Lenses: Tips and Best Practices
Proper care of contact lenses is vital to prevent infections and ensure long-lasting comfort. Here’s a daily guide to caring for your lenses:
- Clean Hands: Always wash and dry your hands thoroughly before handling lenses.
- Daily Cleaning: Rinse and clean lenses with a multipurpose solution after removing them each day.
- Fresh Solution Daily: Avoid reusing old solution in your lens case. Replace with fresh solution every day.
- Avoid Water Exposure: Do not expose lenses to water, whether from the tap, pools, or showers, as water may contain bacteria that can cause infections.
- Replace Lenses on Schedule: Follow the prescribed replacement schedule (daily, bi-weekly, monthly) without extending the wear time.
Importance of a Proper Contact Lens Fitting
A correct contact lens fitting ensures the lens sits securely on the eye, offering clear vision and comfort without irritation. Improperly fitted lenses can cause issues such as blurred vision, discomfort, and even infections.

We also provide training on inserting, removing, and cleaning your lenses to make the process simple and safe.
When to Replace Your Contact Lens Solution
Using fresh solution every day is critical to keeping lenses clean and safe. Some solutions can expire after a specific duration once opened, so check the expiration dates and adhere to instructions from your eye care provider. At Visualis Eye Clinic, we help you select the right solution based on your lenses and needs, ensuring the highest standard of eye health.
