The brain and the eyes work together to create a visual experience. On one hand, the eyes send signals to the brain, which allows it to translate that data into visuals; on the other, the brain sends signals to the muscles attached to each eye, controlling their movements. If anything disrupts these

Corrective lenses are used to correct deviations, adjust focal points or neutralize other anomalies that impact the eyes’ ability to focus an image on the retina. To do this, the lenses must be the correct type and of the right power. Strength – which is expressed as diopeters – relies on the material

Visual-motor-sensory integration training uses various devices to appeal to a person’s senses, including touch, sound and smell. This type of therapy is particularly useful in children with autism. Devices may include play dough, rubber toys, weighted bells and blankets, water, rice, sand, beans, musical

While moving one’s head and tossing a ball sounds easy enough, they are not simple tasks for persons

A Marsden ball might not look very impressive, but this little ball offers big benefits for athletes and children affected by strabismus, ambylopia and other conditions. Marsden ball exercises are just one of the techniques that vision therapists use to help patients make better use of their vision. What

Automated targets with timing mechanisms not only show the optometrist how the eyes move in the beginning of treatment – when eye problems have yet to be fully addressed – by strategically positioning the targets, but they give weak eyes a necessary workout. By moving the eyes around to focus on

Contact lenses, or therapeutic lenses, are thin lenses that are placed on the surface of the eye. While some wear them for cosmetic reasons, their primary function is to correct and improve vision problems related to refractive errors, act as a protective layer in patients with eye injuries, reduce discomfort

Optical filters carefully transfer light in a specific range of wavelengths or colors while obstructing what remains. These dyed plastic or glass devices are placed in the optical path. They are described by their frequency response, and this identifies how the scale and stage of each frequency component
