- For other uses, see Blindness (disambiguation). Visual impairment, also known as vision impairment or vision loss, is a decreased ability to see to a degree that causes problems not fixable by usual means, such as glasses. Some also include those who have a decreased ability to see because they do not have access to glasses or contact lenses.

Visual impairment Blindness and Low Vision. FACT SHEET. It is estimated that about 1.3 million people in the U.S. are legally blind. Legal blindness refers to central visual acuity of 20/200 or less in the better eye with the best possible correction, or a visual field of 20 degrees or less. Each year 75,000 more people in the United States will become blind or visually impaired.

Cortical visual impairment The term neurological visual impairment (NVI) covers both CVI and total cortical blindness. Delayed visual maturation, another form of NVI, is similar to CVI, except the child's visual difficulties resolve in a few months. Though the vision of a person with CVI may change, it rarely if ever becomes totally normal.

Transient Vision Loss (TVL) Transient monocular visual loss is often referred to as amaurosis fugax, irrespective of the cause. However, it is more accurate to reserve the term amaurosis fugax for episodes of transient monocular blindness resulting from ischemia.A vertebrobasilar disturbance may cause a visual transient ischemic attack (TIA).

Blindness and Vision Impairment Most blind people are 65 years of age and older and the prevalence of blindness rises sharply by age. African-Americans and Hispanics are at higher risk for blindness and vision impairment than Caucasians because they are at higher risk for developing diabetes, diabetic retinopathy, and glaucoma.

Understanding  Cerebral Vision Loss Cortical blindness refers to profound, bilateral vision loss in adults. Cortical visual impairment, a relatively new term, is more applicable to neurological loss seen in children. Visual recovery has ben shown to be variable and related to chronological age of hypoxic insult, severity and etiology.

Top 8 Misconceptions about Cortical Visual Impairment (CVI) 4. CVI is not a true visual impairment. FALSE! Truth: CVI, also known as cerebral visual impairment, is a visual impairment. We may think of vision as only including our eyes. However, the sense of sight is more than the actual physical structure of the eyes. The eyes are connected to the brain to send message about what is in front of the eyes.
