Classification: CPC A  G | IPC A  G

Claim 4:
5. A method of modulating light, comprising:
detecting a property of light entering an eye and a property of light reflected by the eye;
analyzing the property of the light detected by the sensor to select an optimal modulation light property of a light modulator according to the detected property;
controlling the light modulator to have the selected modulation light property; and
modulating the property of the light entering the eye, which is scattered in the eye, to form an inversely scattered light pattern, thereby allowing the light entering the eye to be focused on the retina,
wherein the optimal modulation light property of the light modulator means that when light with a predetermined property enters the eye, the modulation light property of the light modulator has the closest detected value to the detected value for the property of interfering light for a normal eye in which there is no cloudiness,
wherein the modulation light property includes a phase, strength, or intensity of the light, and
wherein the light entering the eye interferes with the light reflected out of the eye, and the interfering light creates an interference pattern according to the degree of eye opacity.
