The present invention relates to a device for self examination of the transparent optical system of the eye comprising: a) a rigid hollow frame having one face with means for fitting said frame to the orbit of the eye; b) a small source of light (either primary or "virtual") located inside said frame; c) means for adjusting the distance between said light source and the cornea, such that when fitted to eye, said distance is in the range of the focal length of an average eye. The device according to the present invention can further comprise motorized or manual means for clearing the beam of light from disturbances and a filter for selecting a specific range of the visible spectrum. The present invention further relates to a method for self examination of opacities within the transparent optical system of the eye (cornea, lens and vitreous humor). |
