MassVAT Designed by: Luisa Mayer, Ph.D. and Bruce Moore, O.D.

The MassVat Design helps to isolate the optotypes for better identification and helps to keep the attention of children longer during the test taking process. MassVat uses contour interaction bars around each line to help keep the child focused on testing. Furthermore, the contour interaction achieved by the MassVat design is a great test for detecting signs of amblyopia.
