subtype: anorthopia distorted vision in which straight lines appear curved
subtype: aphakia absence of the natural lens of the eye (usually resulting from the removal of cataracts)
subtype: blindness__blindnes__sightlessnes lack of sight
subtype: anopia sightlessness (especially because of a structural defect in or the absence of an eye)
subtype: snowblindness__snowblindnes temporary blindness caused by exposure to sunlight reflected from snow or ice
subtype: eyelessness__eyelessnes blindness due to loss of the eyes
subtype: figural_blindness__figuralblindnes inability to see shapes and contours
subtype: color_blindness__colorblindnes__colour_blindness__color_vision_deficiency__colour_vision_deficiency genetic inability to distinguish differences in hue
subtype: dichromacy__dichromatism__dichromatopsia__dichromia__dichromasy a deficiency of color vision in which the person can match any given hue by mixing only two other wavelengths of light (as opposed to the three wavelengths needed by people with normal color vision)
subtype: red-green_dichromacy__redgreendichromacy__red-gree_color_blindness confusion of red and green
subtype: deuteranopia__Daltonism__green-blindness dichromacy characterized by a lowered sensitivity to green light resulting in an inability to distinguish green and purplish-red
subtype: protanopia__red-blindness__redblindnes dichromacy characterized by lowered sensitivity to long wavelengths of light resulting in an inability to distinguish red and purplish blue
subtype: yellow-blue_dichromacy__yellow-blue_color_blindness confusion of yellow and blue
subtype: tetartanopia__yellow-blindness a form of dichromacy characterized by lowered sensitivity to yellow light; so rare that its existence has been questioned
subtype: tritanopia__blue-blindness rare form of dichromacy characterized by a lowered sensitivity to blue light resulting in an inability to distinguish blue and yellow
subtype: monochromacy__monochromatism__monochromatic_vision__monochromaticvision__monochromia__monochromasy complete color blindness; colors can be differentiated only on the basis of brightness
subtype: diplopia__double_vision visual impairment in which an object is seen as two objects; "diplopia often disappears when one eye is covered"
subtype: hemeralopia__dayblindnes inability to see clearly in bright light
subtype: hemianopia__hemianopsia blindness in one half of the visual field of one or both eyes
subtype: quadrantanopia blindness in one fourth of the visual field
subtype: metamorphopsia a defect of vision in which objects appear to be distorted; usually due to a defect in the retina
subtype: nyctalopia__night_blindness__nightblindnes__moon_blindness inability to see clearly in dim light; due to a deficiency of vitamin A or to a retinal disorder
subtype: photoretinitis damage to the retina resulting from exposure of the eye to the sun without adequate protection
subtype: retinal_detachment__retinaldetachment__detachment_of_the_retina__detached_retina visual impairment resulting from the retina becoming separated from the choroid in the back of the eye; treated by photocoagulation
