Abstract: In one example embodiment, an apparatus for obtaining status information of a crystalline lens of an eye includes a light projector configured to project a reference light to the crystalline lens; an intensity detector configured to detect an intensity of scattered light that is generated from the reference light by being scattered at the crystalline lens; and a calculator configured to calculate thickness information of the crystalline lens based on the intensity of scattered light.

Abstract: Provided are an apparatus for obtaining status information of a crystalline lens and equipment including the same. The apparatus generates a reference light and directs the reference light to be perpendicularly incident to the crystalline lens. At least one light receiving unit that is disposed beyond a visual field of the eyeball is configured to directly receive scattered lights generated when the reference light incident from the light source unit to the crystalline lens is scattered against the crystalline lens. The apparatus calculates thickness information of the crystalline lens using information about the scattered lights received by the at least one light receiving unit.
