Comprehensive vision exams include a determination of your spectacle prescription and also an evaluation of the ocular health to rule out eye diseases such as glaucoma and macular degeneration.
Contact lens examinations include a comprehensive vision exam followed by a contact lens fitting. The fitting of contact lenses involves using instrumentation to view the lenses on the eye. This is done to determine the proper movement and centering of the lens on the cornea. The vision is also assessed while wearing the lenses. This process is more complex when fitting bifocal or astigmatism contact lenses.
