Description of the Book:

Thirty rated U. S. Army aviators with various types of refractive errors were selected to wear-test both clear and tinted plastic (CR-39) ophthalmic lenses for a period of six months. Subjective evaluations were made in the areas of impact resistance, scratch resistance, weight, optical clarity, comfort, cleaning ease, resistance to breakage, and accumulation of foreign material. User acceptance was quite good. Lens scratching was not found to be a significant problem
