Just having bad eyes is not enough to get disability. You have to be blind as well as be unable to work.

If you meet the definition of "Legally blind" and are unable to be employed because of that, you could apply for disability. According to wikipedia: In 1934, the American Medical Association adopted the following definition of blindness: Central visual acuity of 20/200 or less in the better eye with corrective glasses or central visual acuity of more than 20/200 if there is a visual field defect in which the peripheral field is contracted to such an extent that the widest diameter of the visual field subtends an angular distance no greater than 20 degrees in the better eye.[6] The United States Congress included this definition as part of the Aid to the Blind program in the Social Security Act passed in 1935.[6][7] In 1972, the Aid to the Blind program and two others combined under Title XVI of the Social Security Act to form the Supplemental Security Income program[8] which currently states: An individual shall be considered to be blind for purposes of this title if he has central visual acuity of 20/200 or less in the better eye with the use of a correcting lens. An eye which is accompanied by a limitation in the fields of vision such that the widest diameter of the visual field subtends an angle no greater than 20 degrees shall be considered for purposes of the first sentence of this subsection as having a central visual acuity of 20/200 or less. An individual shall also be considered to be blind for purposes of this title if he is blind as defined under a State plan approved under title X or XVI as in effect for October 1972 and received aid under such plan (on the basis of blindness) for December 1973, so long as he is continuously blind as so defined.[9] See for the footnotes: http://en.wikipedia.org/wiki/Blindness

To receive disability, a person must show that they have a substantial impairment (disability) that adversely affects their ability to perform a daily life function. It is not enough to have bad eyes but they must also prevent you from functioning to a degree that you can't perform a major life function. Work is considered one of these functions. You should be aware that this is not considered a substantial impairment if it is correctable with the aid of medical devices...eyeglasses for example are such a correction. It is a complex interconnection of several factors in making these determinations. My advice to you is to get legal counsel to help you make a claim if you feel that you have one and may get resistance from the system.
