Graham-Field Grafco 1240 Snellen Hanging Eye Chart, 20' Distance, Non-Reflective, Matte Finish with Green and Red Color Bar

ITS OK.

Very useful to test our eye sight. Good quality

great chart

Excellent products.

Much bigger than thought but does the job

I measured out 20 feet like they use at DMV so I know if I need to go to the eye doctor sooner rather than later. It’s a good thing to have around and good quality.

Funciona muy bien para espacios reducidos, en donde no tienes 6 metros de distancia. La calidad del plástico es buena, se ve resistente. Las letras muy nítidas. Ponerlo frente a una fuente de luz funciona mucho mejor todavía. 100% recomendado.

Pour ma blonde et elle l'adore

I bought this for use at our medical office. Although we have several corridors over 20 feet in length, there is poor ceiling lighting above the spot where the chart would have to be placed. Also, because there are exam rooms all along the corridor, and because the examiner and the patient have to use fairly loud voices to communicate over 20 feet, the noise created does not contribute to a quiet atmosphere for patients waiting inside the rooms, or for physicians in the exam room trying to converse with the patient.Our vital signs/intake room (scale, BP cuff, oximeter) is exactly 10 feet long and brightly lit, so we hung the chart at one end and the patient stands in the doorway facing inward to view the chart. Communication between examiner and patient remains within the room and does not echo down the corridor, plus one need not speak as loudly at only 10 feet away.This chart is suitable for literate adults and children old enough to know the alphabet. 10 foot eye charts with symbols are available for non-literate adults and young children.
