Intended use
The ACP-905P is a 23.6-inch polarised vision testing display for examining visual acuity, refraction and binocular vision. The examination distance is 2–7 metres.
Thanks to polarisation, the ACP-905P enables a wide range of binocular and stereo vision tests without red–green glasses. The display also includes the standard visual acuity optotypes and the test charts used in refraction and in assessing visual functions.
The brand of the ACP-905P is Canton. The non-polarised version of the series is the ACP905C, on which binocular and stereo vision tests are performed with red–green glasses.
