Abstract
A soft contact lens 5 comprises a cosmetic coloured area 6 and an opaque iris 7 with a plurality of pinholes 8 arranged so as to direct light 1 to a light sensitive part of the retina of a wearer 10. The wearer's ophthalmic prescription may be incorporated into the contact lens. One embodiment may be a trial contact lens designed to determine the optimal pinhole arrangement for a wearer, e.g. by axis markings [12, figure 7]. The contact lens may be truncated or back weighted to stabilise its position in the wearer's eye 9 (Figures 8, 9). Prisms such as yoke prisms (figures 13, 14) may be included to alter the direction of the light transmitted by the pinholes 8 into the eye 9. The contact lens pinhole 8 positioning may be based on the results of digital retinal mapping. The contact lens wearer may further add magnification by the use of LVA (low vision aid) telescopic systems. The device may remedy retinal damage related sight loss e.g. age-related macular degeneration (AMD). Prism lenses may also be used to decentre a single central pinhole image transmitted by a single pinhole contact lens.
