Our specialty lens technology products

We are specialty lens pioneers. Founded in 1992, BostonSight developed the first fluid-ventilated scleral lens using a gas-permeable material. This innovation was the beginning of the current scleral lens industry. Scleral lenses can treat a variety of corneal and ocular surface diseases. For more complex or severe disease, PROSE® treatment offers additional customization and medical care.

PROSE® Treatment

PROSE treatment by BostonSight is a custom, non-surgical medical treatment that helps people living with corneal and ocular surface disease find lasting comfort, clarity, and quality of life. For many people, PROSE is their only option to restore vision and end suffering from critical and devastating eye issues.

In their own words

“I am an ophthalmologist. Without the PROSE contact lens, I would no longer be working as an ophthalmologist. Surgery would be impossible. Thank you for everything!”

“Their years of research has truly advanced the use and prescribing of scleral lenses, providing more accessibility for patients need this technology worldwide.”

“No ask is too big to them. We are always able to get to a point with BostonSight SCLERAL that we get a good outcome.”

“We nailed it pretty much on our first try, which was amazing. Normally, these would take a lot of revisions, but with the Pentacam, the BostonSight SCLERAL, and FitConnect, we got a lens really quickly that the patient could wear.”
