When standard contact lenses fail to provide comfort or clear vision, large-diameter contact lenses serve as an advanced alternative. Designed to cover a greater portion of the eye’s surface, they offer stability, comfort, and superior hydration, making them an excellent choice for individuals with unique vision needs or sensitive eyes.
These lenses function by creating a fluid reservoir between the cornea and the lens surface. This reservoir ensures consistent moisture and sharp vision throughout the day. Their precise design and customized fit allow them to perform effectively even in complex corneal conditions.
What Are Large Diameter Contact Lenses?
Large diameter contact lenses (often known as scleral lenses) are advanced lenses that extend beyond the cornea and rest gently on the sclera, the white part of your eye.
This unique design creates a fluid-filled layer between the lens and cornea, providing both comfort and consistent vision throughout the day.
Unlike standard lenses that only cover the cornea, large-diameter lenses offer:
- Enhanced stability
- Reduced irritation
- Long-lasting moisture retention
They are custom-designed to fit each eye precisely, ensuring a smooth and secure wearing experience.
Who Can Benefit from Large Diameter Contact Lenses
These lenses aren’t just for special cases, they can help many people see and feel better every day. Check who benefits most below.
- Patients with keratoconus or irregular corneas who cannot achieve clear vision with glasses or standard contacts.
- Individuals with post-surgical corneas, such as after LASIK, corneal transplants, or cross-linking.
- People with chronic dry eye benefit from the moisture reservoir these lenses provide.
- Patients who cannot tolerate regular soft or RGP lenses due to discomfort or sensitivity.
- Anyone seeking stable, long-lasting vision with a comfortable, secure lens fit.
Complete Fitting and Customization Process
Comprehensive fitting and customization ensure that your large diameter lenses match the exact shape and curvature of your eyes.
The process involves the following steps:
Eye Examination
We carefully evaluate your eye health, corneal shape, and tear film to determine if large-diameter lenses are the best solution for you.
Advanced Corneal Mapping
We use advanced diagnostic tools to create a detailed 3D map of your cornea and sclera. This mapping captures every curve and contour of your eye’s surface. It allows us to design your large diameter lenses with maximum precision for a perfect fit.
Trial Lens Testing
You will try on trial lenses during the fitting process. We closely assess vision clarity, comfort, and lens stability on your eyes.
This testing ensures the final lenses deliver the best possible results for your vision and comfort.
Custom Lens Design
Each lens is digitally designed to perfectly match the natural shape of your eye. This tailored design keeps the lens stable and prevents it from shifting. It ensures clear vision and lasting comfort from morning to night.
Follow-Up Adjustments
After you get your lenses, we schedule checkups to fine-tune their fit. These visits help keep your vision clear and your eyes comfortable in the long run.
Benefits of Large Diameter Contact Lenses
These lenses are not just larger, they are designed with smarter technology and precision.Their unique features enhance comfort, stability, and vision quality. Here is what truly makes them stand out from standard contact lenses:
1. Clear and Stable Vision
They form a smooth optical surface that reduces visual distortion. This design ensures sharp, consistent clarity throughout the day. It also provides stable vision, even for eyes with irregular corneas.
2. Continuous Hydration
The fluid reservoir beneath the lens continuously hydrates your eyes. It helps prevent dryness and irritation throughout the day. This makes the lenses ideal for chronic dry eye or extended screen time.
3. Exceptional Comfort
Their scleral fit provides a smooth, stable placement on the eye surface. It prevents the lenses from moving or rotating during wear. This design also eliminates irritation or discomfort caused by lens edges.
4. Durable and Reliable
Made from high-quality materials, these lenses retain their shape and clarity over time. They resist buildup and surface deposits, ensuring consistent performance. Their durable design allows them to last significantly longer than standard lenses.
5. Enhanced Protection
By covering a larger area of the eye, these lenses create a protective barrier. They shield the cornea from wind, dust, and other environmental irritants.This protection helps maintain eye comfort and overall ocular health.

Frequently Asked Questions
How are large-diameter lenses different from standard lenses?
Large-diameter lenses vault over the cornea and rest on the sclera, unlike standard lenses that sit directly on the cornea. This provides more stability, comfort, and hydration.
Can I sleep in large-diameter lenses?
No, these lenses should be removed before sleeping to let your eyes breathe and avoid the risk of infection.
How long does it take to adjust to these lenses?
Most patients adjust within one to two weeks. Your optometrist will guide you through the adaptation process step by step.
How do I clean and store large-diameter lenses?
Always use approved cleaning and disinfecting solutions — never tap water. Follow your eye doctor’s care instructions carefully.
Does insurance cover large-diameter lenses?
Yes, if prescribed for medical conditions like keratoconus or post-surgical recovery, insurance often covers part or all of the cost.
