E-Y-E-Check

As you know, staring too long at computer, television, mobile phones and digital devices screens may result in digital eyestrains and other visual abnormalities, such as short sightedness. With E-Y-E-Check, you can now self check your visual acuity. Check it regularly and see whether your vision is stable or worsen.

E-Y-E-Check uses tumbling 'E' for testing visual acuity. In general, you cover one of your eyes and hold/place your phone 50cm to 100cm (user specified) from your non-covered eye. Each time a letter 'E' will appear on screen in a direction picked out from 'left', 'right', 'up' and 'down' randomly. Within 10 seconds, you read out the 'E' direction in the language selected previously, English, Chinese Mandarin or Cantonese, and you will know whether you are correct or wrong.

E-Y-E-Check has 3 testing modes:
1. Full Test: 10 Tumbling 'E's from large (Row 1: 20/200) to small (Row 10: 20/20), 1 direction from each size.
2. Mini Test: 8 Tumbling 'E's from Row 7 (20/40) to Row 10 (20/20), 2 directions from each size.
3. Specific Row: 10 random directions from the Row you specified.

Anyway, if you have any problem with your eyes, please consult an ophthalmologist immediately.
