RELATION OF FACTORS INVOLVED IN MAINTENANCE OF OPTICAL PROPERTIES OF CORNEA TO CONTACT-LENS WEAR

RELATION OF FACTORS INVOLVED IN MAINTENANCE OF OPTICAL PROPERTIES OF CORNEA TO CONTACT-LENS WEAR Abstract AMONG the problems confronting the use of contact lenses is the change in optical properties of the cornea which occurs when the conventional contact lens is worn. The effect of contact lenses on the physiology of the cornea is the subject of this communication. When a conventional contact lens is worn, after a variable period the subject experiences development of a haze or mistiness in his vision (Sattler's veil) and sees colored halos or rainbows about light sources. These changes slowly disappear after the contact lens is removed. Since these optical phenomena are definite and subject to measurement, they were selected as the criteria in this study by which the effect of contact lenses on corneal function could be judged and measured. There are many possibilities by which a contact lens might be expected to affect the cornea. 1. The type, shape, and point of contact of a lens with References 1. Dallos, J.: Sattler's Veil , Brit.

Abstract

Abstract AMONG the problems confronting the use of contact lenses is the change in optical properties of the cornea which occurs when the conventional contact lens is worn. The effect of contact lenses on the physiology of the cornea is the subject of this communication. When a conventional contact lens is worn, after a variable period the subject experiences development of a haze or mistiness in his vision (Sattler's veil) and sees colored halos or rainbows about light sources. These changes slowly disappear after the contact lens is removed. Since these optical phenomena are definite and subject to measurement, they were selected as the criteria in this study by which the effect of contact lenses on corneal function could be judged and measured. There are many possibilities by which a contact lens might be expected to affect the cornea. 1. The type, shape, and point of contact of a lens with References 1. Dallos, J.: Sattler's Veil , Brit.
