More than 300,000 sports-related concussions occur each year, according to research. Many more concussions result from motor vehicle accidents, falls, and other non-sports related incidents. In addition to causing cognitive difficulties, concussions may result in a cluster of problems called post-concussive

The cognitive differences of special needs children and adults are well-documented, but vision issues often receive less attention. People with special needs have the same range of vision issues as their neurotypical counterparts; however, these vision problems occur at a much higher rate in special

Accurate vision involves much more than good eye health. The brain integrates signals from the eyes with information from the motor, balance, and auditory systems to create an accurate view of the world. Following traumatic injury, one or more components of this complex system may be damaged. Receiving

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

These exercises are mainly used at home and range from simple head and eye movements to performing more complex activities like throwing a ball or focusing on a stationary object while the head is moving. 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

This device integrates all of the senses used for learning. It is one of the basic instruments used for visual-motor training, and helps with direction, rhythm, eye-hand coordination, and work and shape recognition. It consists of an aluminum case with illuminated membrane switches organized along a

Amblyopia, commonly called lazy eye, refers to the improper development or significant loss of vision in an eye. It occurs when the brain does not acknowledge the images seen by the amblyopic eye. Amblyopia Causes Amblyopia occurs when an individual cannot use binocular vision (both eyes working together)

Here, a ball with letters, numbers, colors, pictures, or a combination is hung from the ceiling. In activities used to help focus visual attention, the individual may be asked to concentrate on a figure while bunting the ball with a rod, or hitting or catching it with their thumbs, palms or fists.

Known also as optometric phototherapy, syntonics deal with the application of selected visible-light frequencies and are used to treat lazy eye and problems with peripheral vision and depth perception. By applying particular visible-light frequencies through the eyes, syntonics can improve vision. This

There are many potential causes for blurry eyes. The answer to why you have blurry vision is best answered by your eye care professional, who can offer diagnosis and prompt treatment so that your vision does not get worse. Some conditions that cause blurry vision are easy to treat, but others require
