INTRODUCTION:
In addition to saving and maintaining eye health, optometrists perform surgery and prescribe glasses to help patients use central eyesight at a conscious level to identify 20/20 letters (non-moving targets). The quality of central eyesight is often dependent on the stability of the peripheral eyesight. However, peripheral processing of moving targets is usually at a subconscious level. Eye glasses prescribed for central eyesight do not necessarily address peripheral processing and are not sufficient in some patients – such as those who have autism or a brain injury.
