WebDefects of Vision And Their Correction. Defects in the eye happen due to many reasons. Due to growing age, the vision also decreases, and when the focal length alters, the vision also alters. We know that cataract is a common defect seen in the eye. Cataracts cause partial or sometimes complete vision loss when not treated properly. WebFLAASH is a first-principles atmospheric correction tool that corrects wavelengths in the visible through near-infrared and shortwave infrared regions, up to 3 µm. (For thermal regions, use the Toolbox option Radiometric Correction > Thermal Atmospheric Correction .) FLAASH works with most hyperspectral and multispectral sensors.
