Hand Motion Vision:
Some eye injuries are so catastrophic that almost no visual acuity remains. At the extreme end, patients are left with what is termed "hand motion vision," meaning that while the patient can recognize a hand being waved, he or she cannot count the fingers on the hand. The simulation depicts vision substantially similar to that of a patient who received the wrong eyedrops following cataract surgery.
