Manual Distance Vision Drum

​The Manual Distance Vision Drum is a classic ophthalmic tool used to assess a patient's distance visual acuity accurately. It features a cylindrical rotating drum mounted on a wall or stand, with multiple printed vision charts such as Snellen, Landolt C, Tumbling E, and picture charts for children. Each panel of the drum can be manually rotated to present different test charts, allowing eye care professionals to conduct comprehensive vision testing without needing separate charts. Constructed from durable fiber or metal, the drum ensures long-term usability and stable performance. The charts are printed in multiple languages including English, Hindi, Urdu, and Punjabi, making it suitable for diverse patient populations. It is designed for use at a standard testing distance of 6 meters (20 feet), providing consistent and reliable results. Ideal for clinics, hospitals, and eye camps, the Manual Distance Vision Drum is an essential, cost-effective tool for everyday visual acuity screening.
