Ready made or stock artificial eyes are mass-produced. A custom made artificial eye on the other hand, is made by your ocularist to fit you and you alone, matching any detail.

Except as a temporary prosthesis, or in the case of an indigent patient where no custom designed prosthesis can be afforded, there are no pre-fabricated or 'stock' eye prosthesis fabricated or provided to any individual or dispensor.

Stock eyes are chiefly supplied by the state hospitals at a subsidised rate.
