Other important details
1. Observe your child noticing hand movements and developing eye-hand co-ordination.
The patch on the lens may also be translucent half or full cover. If full cover of a lens is used, then it is important that the infant/child does not look over the frame. If that occurs, full occlusion with a patch is necessary to force the infant to use the lazy eye. It is then important that the lazy eye has high quality visual information for training - and it must be sure that the eye or the optic nerve are not damaged so badly that training will not improve function.
