DISCLAIMER:
Due to variations in each screen accuracy (screen size, brightness/contrast, resolution) the eye tests are not perfect. Holding a phone of approx 4" screen size 30 cm/12 inches from your eyes would give you nearly accurate results. Hold it (place it) 52cm/20inches from your eyes if you have e.g. a 7" tablet.
Do not consider the tests in the app official tests. These tests only mean to give you an idea whether or not you should see an eye doctor or go on an eye therapy.

VISUAL ACUITY
The visual acuity test is a routine part of an eye examination, particularly in case of vision problems. At a young age, these vision problems can often be corrected or improved. Undetected or untreated vision problems can lead to permanent vision damage.

The cause is the photoreceptor in your eyes, called Melanopsin. This receptor is sensitive to a narrow band of blue light in the 460-480nm range which may suppress melatonin production - a hormone responsible for your healthy sleep-wake cycles.

In experimental scientific studies it has been shown an average person reading on a tablet or smart phone for a couple of hours before bed time may find their sleep delayed by about an hour.

The twilight app makes your device screen adapt to the time of the day. It filters the flux of blue light emitted by your phone or tablet after sunset and protects your eyes with a soft and pleasant red filter. The filter intensity is smoothly adjusted to the sun cycle based on your local sunset and sunrise times.

What to do if I get bad results?

If your results indicate you may have vision problems, you should see an eye doctor. Having regular eye examinations promotes eye health. It also allows your doctor to measure your vision and make the necessary changes to your prescriptions.
You can also download eye training apps to preserve your eye sight and improve vision. You should take better care of your eyes and vision. Preserving vision health is one of our most important thing to do. Omitting eye care and eye exams can result in serious vision damage.

If you experience any eye problems using the web browser, to-do apps, calendars, writing messages or checking the phone book or the call log, you should take this test to check if you need eye treatment and/or vision training.
