CONTACT LENSES: AN EVALUATION STUDY

Abstract

Contact lenses and spectacles were compared to determine their relative merits and applications. The contact-lens types studied were: (1) a plstic, fluid, corneal-scleral design; (2) a plastic corneal design; (3) a plastic, ventilated, fluidless corneal-scleral design, and (4) a glass, ventilated fluidless cornea-sclreal design. The fluidless, ventilated lens proved superior to either the fluid or corneal type. The plastic lens appeared to offer greater protection of the eye since the lens is not easily broken. The major objection to plastic was attributed to poor wetting properties. In general, the contact lenses offered advantages in military field activities but were not superior in performance to spectacles in routine and clerical work. Contact lenses appeared particularly advantageous for use in inclement weather, arctic duty, swimming and violent activity. Corneal clouding was no longer a problem with the newer designs.
