Opticians generally do a good job of correcting one’s eyesight using lenses.
Today’s invention is a new system in which the correction is only partial.
The lenses that one ends up wearing would be only 90% corrective. This leaves the wearer constantly having to exercise their eye muscles a little in order to make up the shortfall and achieve focus. This exercise alone would be enough to reduce one’s reliance on glasses and perhaps even reduce the deterioration in one’s vision over time.
