Alaska Blind Child Discovery

A cooperative, charitable research project to vision screen every preschool Alaskan


Surrounded Optotypes best select amblyopic patients. In a logMAR presentation, children under Kindergarten unable to pass the 20/40 critical line, or over Kindergarten unable to pass the 20/30 line, should be referred for a confirmatory examination. There should be a low chance the child can merely guess the critical line by chance; therefore 3 out of four, or four out of five are needed. With the six (6) bilaterally symmetric simple capital letters in HOTVAX, only two out of three yields a less than 0.03 chance of guessing- and speeds up the acuity screening process.    
Nordic and Alpine ski racers use HOTWAX, or in German HOTVAX, to make the skis go faster.
