The 3 Metre Eye Chart Direct is a chart featuring standard Snellen lettering suitable for opthalmologists, optometrists & general vision assessment in limited space environments.
Mount it on the wall and have the patient stand back 3 metres and read. This chart is easy to mount using blu-tac or similar products and is manufactured by BOC.
The 3 Metre viewing distance makes this chart suitable for smaller offices, mobile clinics and other spaces where standard 6m viewing length is not possible.
