Bill Cosby is visually impaired, according to this defense lawyers.
Cosby's defense attorneys on Thursday filed a motion that states the 79-year-old comedian is "legally blind."
By law, a person is considered legally blind if he or she has a visual acuity of 20/200 or less in the better eye, according to the Massachusetts Commission for the Blind.
His lawyers' argument is that he cannot determine whether he has even seen the more than 50 women who have spoken out about allegations of sexual misconduct by Cosby.
Cosby faces three charges of felony indecent assault stemming from a 2004 incident involving Andrea Constand, an employee at his alma mater, Temple University.
Here's how this could help his case
Cosby's lawyers argue that his visual impairment will affect his ability to defend himself at his criminal trial.
"No 79-year-old blind man could possibly defend himself against a claim that he sexually assaulted someone he supposedly met once, half a century ago -- and the Commonwealth knows it," they said.
The defense argues his loss of sight will make it difficult for him to develop defenses and gather exculpatory evidence.
What's next for Cosby?A copy of a doctor's report will be provided at the next hearing in the case, set for Tuesday.
The motion is an effort to get the accusations dismissed.
A tentative trial date has been set for June 5.
