Do you need new corrective glasses? Or just want to know you eyes' refractive error? Search no further. Feyenally is here to help!

Measure your eyes' refractive error at home, using just your smartphone. Our cutting-edge solution is the first one in the world to use objective testing methods. This means, the measurement does not rely on your feedback (unlike traditional visual acuity tests) but the test is performed based on the photos of your eyes.

What you get as a result is a comprehensive information that you need for ordering your corrective glasses or lenses:
- Sphere (DS) indicating shortsightedness or farsightedness
- Cylinder (DC) indicating astigmatism
- Axis (Deg)

There are just a few steps to be performed:
1. Go to a dark room (with no direct source of light).
2. Hold the phone at arm's length (about 50cm/1.65ft) in front of you (at your eyes' level) with the rear camera facing you.
3. Do not look at the phone but right next to it - look at an object (or into the dark) that is further behind your phone.
3.1 Left eye: keep the phone 15cm/0.5ft to the left from your line of sight.
3.2. Right eye: keep the phone 15cm/0.5ft to the right from your line of sight.
4. Close your eyes for 15 seconds.
5. Open your eyes wide and wait for the picture to be taken automatically (still not looking directly at the phone). If needed, try moving a phone slowly back and forth and to the sides.
6. The measurement is considered complete when you see the back light flashing. You can preview the picture - make sure it is not blurred.
