System to image the human eye corrects for chromatic aberrations

Researchers report a new imaging system that cancels the chromatic optical aberrations present in a specific person’s eye, allowing for a more accurate assessment of vision and eye health. By taking pictures of the eye’s smallest light-sensing cells with multiple wavelengths, the system also provides the first objective measurement of longitudinal chromatic aberrations (LCA), which could lead to new insights on their relationship to visual halos, glare and color perception.
