You hear the term color blindness but what exactly does it mean? Color blindness is more accurately described as a color deficiency. Basically, it s the inability to distinguish certain shades of color.
Individuals who have a color deficiency have trouble seeing shades of red and green or blue and yellows. Though possible,  complete absence of color vision is quite rare.
Red-green defects are the most common, occurring in males more often than females. Blue-yellow effects males and females equally and occur in fewer than 1 in 10,000 people wordlwide.
Though a color deficiency is usually a genetic condition there are a few diseses that can cause color deficits including 1
  • Diabetes
  • Glaucoma
  • Macular Degeneration
  • Alzheimers
  • Parkinsons
  • MS
  • Leukemia
  • Sickle Cell Anemia
Diagnosing color vision deficiency is very simple and can be done on even the youngest of patients. Using the Ishihara Plate test, the patient simply identifies what number is seen in the plate, identifies a shape or traces a line.
Though there is no cure it is possible to improve. Special contacts or tinted lenses can help the patient learn to differentiate. 
If your child hasn't been screened yet, why not schedule an appointment to have their vision tested. We are accepting new patients. (419) 334-8121 or (419) 435-3482
