The MassVat format incorporates boxes around optotypes that are referred to as contour interaction bars. These bars help children focus on each line and can raise testing results. Also, the contoured interaction bars help detect early signs of childhood Amblyopia. Patti Pics optotypes coupled with the MassVat design, create an easy to use and accurate pediatric vision test.
