Why scleral lenses work when nothing else does

Every condition in the simulator above shares one root problem: an irregular or unprotected corneal surface that scatters light before it can focus. Glasses and soft contact lenses can only correct focus after the damage is done — they can’t smooth the surface itself. A scleral lens solves the problem at its source: it vaults over the entire cornea without touching it, and the reservoir of preservative-free saline trapped underneath becomes a perfectly smooth new optical surface. The distorted cornea is still there — it just no longer does the focusing.

The same fluid reservoir is why scleral lenses are also a frontline treatment for severe dry eye: the cornea spends the entire day bathed in moisture, shielded from air, wind, and the friction of blinking.

Because no two irregular eyes are alike, the fit matters as much as the concept. At Michigan Contact Lens we use profilometry-guided free-form scleral designs that map the full surface of the eye, along with higher-order aberration correcting optics for eyes that need more than a standard design can give.

A scleral lens evaluation will show you — often in the very first visit.
