Document Type and Number:
Japanese Patent JP2012215808
Kind Code:
A
Abstract:
To provide methods of fabricating and prescribing lenses suitable for color blindness and dyslexia correction.
A 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 a step 64 for selecting a first visual filter from a set of sixteen filters and a step 66 for selecting a second visual filter from the remaining set of fifteen filters, the first for the dominant eye and the second for non-dominant eye.
