Comparatively good vision in poor light but poor vision in good illumination. The condition is usually congenital and associated with poor ‘visual acuity and defective color vision. Acquired cases occur when the cones (light-sensitive cells) at the back of the retina are selectively destroyed by disease.<\/p>\n
A condition in which the patient sees better in a dim light or by night than in daylight. It is only found in conditions in which the light is very glaring, as in the desert and on snow, and is relieved by resting the retina \u2014 for example, by wearing coloured glasses for a time.<\/p>\n
An inability to see in daylight; hemeralopia.<\/p>\n
