How Are Scleral Lenses Different from Regular Contact Lenses?

Contact lenses have come a long way in offering clearer vision and comfort for people with various eye conditions. While traditional soft lenses are a popular choice, scleral lenses provide unique benefits for patients with specific vision challenges or corneal irregularities. Understanding how these lenses differ can help you make the best decision for your eye health.

What Are Scleral Lenses?

Scleral lenses are larger, rigid gas-permeable lenses that vault over the cornea and rest on the white part of the eye (the sclera). This design creates a tear-filled space between the lens and cornea, offering both protection and hydration. They are custom-made to fit each patient’s eyes and are ideal for individuals who struggle with irregular corneas, keratoconus, dry eye syndrome, or post-surgical vision issues.

Size and Fit

Regular soft contact lenses typically range from 9 to 10 millimeters in diameter and rest directly on the cornea. In contrast, scleral lenses are much larger - between 14 and 20 millimeters - and rest on the sclera. This design eliminates direct contact with the sensitive corneal surface, enhancing comfort and stability.

Material and Breathability

Soft contact lenses are made of hydrogel or silicone hydrogel materials, which allow oxygen to pass through to the cornea. Scleral lenses, while rigid, are made of gas-permeable materials that also allow oxygen transmission, ensuring your eyes remain healthy. The tear-filled reservoir beneath the scleral lens provides constant hydration, reducing irritation and dryness.

Vision Correction Capabilities

Standard contact lenses are designed for common vision problems like nearsightedness, farsightedness, and astigmatism. Scleral lenses, on the other hand, are often used to correct complex vision issues caused by corneal irregularities. Their unique shape provides a smooth optical surface, significantly improving vision for patients who cannot achieve clear sight with glasses or soft lenses.

Comfort and Stability

Because scleral lenses rest on the less sensitive sclera rather than the cornea, many patients find them more comfortable once properly fitted. They are also less likely to move out of place, making them ideal for individuals with active lifestyles or those who have experienced lens displacement with regular contacts.

Specialized Applications

While anyone can benefit from scleral lenses, they are particularly beneficial for patients with:

• Keratoconus

• Severe dry eyes

• Corneal scarring

• Post-surgical vision changes (such as after LASIK or corneal transplants)

Are Scleral Lenses Right for You?

If you’ve struggled with comfort or clear vision using traditional contacts, scleral lenses might be the solution you’ve been looking for. They provide superior stability, moisture, and clarity - especially for patients with unique corneal conditions or chronic dryness.
