It discusses the special occupational conditions experienced by military personnel, particularly in extreme environments, that give rise to the question of whether or not to use contact lenses. Experts in optometry, ophthalmology, visual psychophysics, and engineering describe recent developments in design and use; and representatives of the military services provide examples of actual situations in aerospace settings. Considerations in Contact Lens Use Under Adverse Conditions will be of particular interest to those involved in the design of contact lenses and those responsible for occupational safety and health matters in the private sector. 606 $aContact lenses 606 $aOphthalmic lenses 615 0$aContact lenses. 615 0$aOphthalmic lenses. 676 $a617.7523 701 $aFlattau$b Pamela Ebert$01806720 712 02$aNational Research Council (U.S.).$bCommission on Behavioral and Social Sciences and Education. 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910953853403321 996 $aConsiderations in contact lens use under adverse conditions$94356057 997 $aUNINA
