According to the CDC, about three percent of Americans who are 40 years old or older are either legally blind or are visually impaired. About twenty-one million Americans report functional vision problems or eye conditions. These conditions can significantly compromise vision. If you are legally or statutorily blind, you may qualify for SSDI benefits. If you have suffered vision loss, it is important to know that the Social Security Administration looks at vision loss a bit differently than other types of disabilities.
