School Bus Test

This quick and simple pass/fail test for eye alignment is ideal for screening both per-school and school age children. The size of the school bus at 16 inches matches the criteria established in the Orinda study for vertical and horizontal phorias. When used with the included Maddox rod and penlight, the child simply responds that the line touches the bus or is outside the bus.
