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 simulates 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 Es from large (Row 1: 20/200) to small (Row 10: 20/20), 1 direction from each size.
2. Mini Test: 8 Tumbling Es 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.
