Visually Impaired Background

Visual impairment refers to a person's inability to see normally, whether the vision loss is either partial or the person is completely blind. Visual impairment can be caused by various reasons, though disease, congenital birth defects, and injuries may prove to be the most common.

Impaired Driving

People that are considered to be visually impaired may, under certain circumstances, be allowed to obtain a license and operate a motor vehicle. The United States has laws that vary from state to state that implement certain requirements and testing procedures in order to deem a visually impaired person capable of driving.

Products for the Visually Impaired

There are a long list of products that exist for the visually impaired, all designed with the purpose of not only aiding their vision, but also to provide for a better quality of life. Products for the visually impaired exist for various degrees of vision loss, ranging from mild cases to those that are completely blind.

Cortical Visual Impairment

Cortical visual impairment refers to the impairment of vision that is caused by factors stemming from a disorder of the brain and not the eye itself. Cortical visual impairment is caused by various consequences, though the most frequent tends to be defects that occur during the development of the brain.

Eye Movement

The movements of the eye can be either voluntary or involuntary. Eye movements occur for the purpose of assessing and gathering visual stimuli in order for the brain to process the information. All eye movements, regardless of their nature, are all controlled by the brain.
