The fractal feature which strengthens tear fluid exchange
Document Type and Number:
Japanese Patent JP6165446
Kind Code:
B2
Abstract:
Feature patterns may be incorporated into the peripheral region of the back curve surface of contact lenses in order to increase tear exchange between the contact lens and the cornea. The feature patterns may be based upon fractal geometry and be incorporated anywhere in the periphery of the lens. The placement feature patterns are preferably determined utilizing a combination of simulations and experimentation.
