corneal lens

He also worked with the original Touhy corneal lens.

When the corneal lens focuses on a distant object, the image falls short of the retina and appears blurred.

Müller called his development Hornhautlinsen or 'corneal lenses'.

Early corneal lenses in the 1950s and 1960s were relatively expensive and fragile, resulting in the development of a market for contact lens insurance.

PMMA corneal lenses became the first contact lenses to have mass appeal through the 1960s, as lens designs became more sophisticated with improving manufacturing (lathe) technology.

In 1889, he presented at the university his doctoral thesis titled Eyeglasses and corneal lenses in which he described his efforts to grind scleral lenses from blown glass.

Regardless of the lens size, it is thought that the larger the GP lens, regardless of the fact that it is a rigid lens, will in most cases be more comfortable then standard rigid corneal lenses, and at times more comfortable than soft lenses.
