I asked on the OCA website (Orthodox Church In America)
I was happy to receive an answer within a few minutes.
Below is the response
The complete lack of sight would be an impediment to ordination as one who serves as a priest, both liturgically and practically, must be able to see what he is doing, and especially be in a position to read from Scripture publicly as well as the prayers in the service books. Some forms of blindness -- the type where people can see poorly but with corrective lenses can, even though perhaps considered legally blind in some places -- might not be an impediment, but such matters are evaluated individually by ordaining bishops.
