The distance vision drum carries graded optotypes on a rotating cylinder for simple distance acuity testing. Lightweight and power-free, it suits screening camps and basic clinic use.
What to check before ordering
- Optotype series. Confirm which graded series is printed and the distance it is intended for.
- Stand or handheld. Tell us how it will be used — camp tables and clinic walls need different things.
- Durability. For repeated transport, ask about the drum and housing construction.
- Room length. Check your available testing distance before choosing between a drum and a wall chart.
Typically ordered with
A near vision drum, Ishihara test book and a streak retinoscope — or browse the full ophthalmic range.
