Micropsia is a condition affecting human visual perception in which objects are perceived to be smaller than they actually are. Micropsia can be caused by optical factors (such as wearing glasses), by distortion of images in the eye (such as optically, via swelling of the cornea or from changes in the shape of the retina such as from retinal edema, macular degeneration, or central serous retin… WebOptical engineers classify aberrations into two types: monochromatic and chromatic. Monochromatic aberrations are classified at a single wavelength, but, notably, their relative magnitudes vary with focal length. The individual aberrations are: spherical, field curvature, coma, astigmatism, and distortion.
