The First Ever Japan-made Extended EDOF Contact Lens
SEED 1dayPure EDOF is a daily disposable soft contact lens for presbyopia which is entirely made in Japan. Working jointly with Brien Holden Vision Institute, a world-renowned research institution, Extended Depth-Of-Focus(EDOF) technology is adopted, providing good vision at all distances, while minimizing ghosting and haloes.
Good Vision at All Visual Distances
Single vision lens
With a design based on the EDOF theory, the SEED 1dayPure EDOF contact lens provides good perceived image quality at all distances throughout the range of depth of focus
Stable Visual Performance in Every Condition
SEED 1dayPure EDOF lens is characterised by a combination of multiple higher order aberrations tuned to optimise retinal image quality over a wide range of viewing distances, pupil sizes and decentrations.
Users can expect stable visual performance under various conditions.
