Contact lenses have cosmetic value; the patient need not wear specs. Further, side vision is better with contact lenses. Contact lenses should be used if the difference in power of the two eyes is more than 5 dioptres since the patient will start seeing double if he uses glasses. This is because the two eyes cannot cope with a difference of more than 5 dioptres with glasses. Contact lenses give a more normal image than spectacles. Contact lenses are also preferred in refractive errors of high degrees.Lens care requires only few minutes each day, good hygiene and good habits.
