Halo in the Eyes
Light diffraction can result from clouding of your eye lens as light enters your eye. This can create the appearance of a halo [11] around sources of light. Halo rings around the light that you see can cause driving to be challenging, and these halos are often in different colors. If you have cataracts, this may be why driving in the night, especially in a busy street where headlight and streetlight get into your eyes, can be difficult and unsafe. These symptoms can appear together or separately and must be evaluated by an ophthalmologist in order to make the diagnosis, and the appropriate treatment can be established. However, due to the slow development of cataracts, the manifestation of symptoms may take time and may not even show till the advanced stage of the abnormality. Due to the fact that cataract is considered a part of the aging process, and its occurrence is dictated by already understandable biological processes, everyone is subject to its development to a certain extent. The best bet is to go with the preventive measure of the development of this eye defect.
