  1. Night and color blindness Visuals: Anastasia Veloudos Facts: Dahlia Glanton Speaker: Madison Williams

  2. Colorblindness • Problems with the cones in a person’s retinas which causes them the inability to determine certain colors apart (cones see reds, blues, and greens. If they are unable to pick up one of these colors, colorblindness is present). • Causes: Genetics Aging Damage to the eye(s) Eye problems such as macular degeneration, glaucoma, cataracts, or diabetic retinopathy

  3. Nyctalopia • An inability to see well or at all in dimly lit areas. • Though not a disease, Nyctalopia is a symptom of an underlying disorder, usually nearsightedness. • Causes: Nearsightedness Glaucoma Cataracts Diabetes Retinitis Pigmentosum Vitamin A deficiency Keratoconus

  4. Prevention • Colorblindness or nyctalopia can be difficult to prevent if the cause is genetic. • However, these two conditions can be contracted by other means. One can protect their eyes by: Wearing UV protective sunglasses to prevent sun damage Get eye exams regularly

  5. Cures and treatments • There is no cure for colorblindness. However, color vision correction glasses are available so that colorblind patients may see all colors. • The only cure for nyctalopiais to test to see if you have any underlying conditions that need to be treated (conditions can vary greatly; get tested first!)

  6. Are you colorblind or have a hard time differentiating colors? • Take the test here at Xrite.com! • See if you can differentiate the hues of the colors. • Remember: Just because you have trouble telling 2 VERY similar colors apart, doesn’t mean you are colorblind.
