This HOTV chart uses a 50% spacing for the MassVat design. Each line is 50% the size of the optotypes it surrounds. By using this calibrated spacing, true contour interaction can occur. This help the child while testing and provides more accurate results. Also, by achieving this, the lines help to detect early signs of Amblyopia.
