NJIT's Vision and Neural Engineering Laboratory is seeking research subjects who have tried progressive lenses (bifocals without the line) and wear them regularly or dislike them and have not had LASIK surgery or any other types of eye surgery. Participants will receive $10 per hour of experimentation. The study will last 3-6 sessions; each session is approximately 1 hour and occurs on different days. We will work with your schedule.
