Abstract: Methods of fabricating and prescribing lenses suitable for color blindness and dyslexia correction are disclosed. The corrective lens may be formed of an optically transparent base material, which is tinted to a desired color for correction by immersion in a colorant dye. The color tinted lens is then tinted by a neutral tint dye to render the lens observable as a regular corrective lens. Prescription of such lenses may be based on a dynamically balanced, or haploscopic, fashion of prescription that comprises selecting a first visual filter from a set of sixteen filters and a second visual filter from the remaining set of fifteen filters, the first for the dominant eye and the second for non-dominant eye.

Abstract: A lens and a method of making lenses suitable for color blindness correction are disclosed. The corrective lens may be formed of an optically transparent base material, which is tinted to the desired color for correction by immersion in a colorant dye. The color tinted lens is then tinted by a neutral tint dye to render the lens observable as a regular corrective lens. If desired, the dyes may be heated during immersion.

Abstract: Color discrimination may be improved by fitting to a patient's eye a plastics contact lens having a tinted central circular section. The optimum tint is determined by testing the effects of a sequence of differently tinted lens on a patient.

Abstract: A process of forming a visible textural surface on a decorative acoustical panel having a fibrous body portion is disclosed herein. This process includes coating an exterior surface of the body with a film of hardening liquid, distributing individual granules of particulate material generally uniformly over a substantial portion of the exterior surface to provide a granular texture to the surface, and coating the granules with a film of hardening liquid, which film is insufficient to eliminate the granular texture but which adheres the granules to the exterior surface. Thereafter a part of the surface on which the liquid coated granules are located is indented. These indentations extend from the exterior surface and penetrate partway into the panel body to cause the displacement of part of the surface, thereby forming wall portions. These wall portions include some of the granules.
