Abstract

This paper may conveniently conclude with a brief review of the conclusions arrived at and the suggestions of interest to the Optometrist. (1) Indoor glare is a matter of faulty lighting installations, faulty architecture and incorrect placing of furniture. Where it is impossible to remedy these conditions the use of an eye shade is helpful. (2) Outdoor glare at night is a matter of incorrect street lighting and car headlights. The former is beyond the sphere of Optometrists, but in the latter case we may assist with such aids as Polaroid or Gradutint spectacles if absolutely necessary. (3) outdoor glare during daylight is mostly due, in healthy cases, to an uncorrected error of refraction, the correction of which with white lenses will ease the glare. Where an absorption lens is required it should be of the lightest tint, which will be effective, and should only be worn for the purpose for which it was prescribed. For general purposes and at the seaside, Smoke, Softlite, Crookes' and Fieuzal are recommended, as they do not alter colour values greatly. On snowfields Crookes' and Fieuzal give greater protection from the ultraviolet. In the northern parts of Australia (tropical and sub-tropical) a heat-absorbing lens such as Infrex should be used.
