Innovative Contact Lens

Enhanced vision contact lens

Innovative new contact lens design that improves spatial vision by reducing chromatic and monochromatic aberrations

About

The new contact lens design uses a novel approach to correct for residual refractive errors and yields significant improvement in vision in both ametropic and emmetropic eyes (i.e., visual acuity, ability to see fine detail, depth of focus, etc). The novel design is based on the extensive knowledge of the visual system built up by a City, University of London professor through years of research in colour vision, optics of the eye, visual psychophysics and neuroscience. The lens works by reducing significantly both the chromatic as well as the monochromatic aberrations in the eye, even for pupil diameters as large as 8 mm. In summary, in addition to providing refractive correction, the new contact lens design improves spatial vision by reducing chromatic and monochromatic aberrations. In addition, there will is also an improvement in depth of field, particularly in the high mesopic range, with additional benefits to early presbyopes.

Key Benefits

It is inexpensive to make using currently available manufacturing methods and is appropriate for both RGP and soft lens designs. People with no refractive errors will also benefit significantly from using the new lens. This creates an opportunity to considerably widen the market that can be addressed with this new lens design. Each expected advantage is justified using known facts about chromatic and monochromatic aberrations in the human eye, the contribution the signals generated in the four classes of photoreceptors in the retina make to our ability to see fine detail and faint objects and the directional sensitivity of cones.

Applications

Contact lens manufacturers will benefit from being able to supply a new type of contact lens with improved visual acuity for their customers
