With glasses, see mobile phone has bulge, what reason is it

With glasses, see mobile phone convex may be due to improper frame, lens power is not appropriate, astigmatism axis tilt and other reasons, the specific analysis is as follows:

1. The frame is not appropriate

If the patient's glasses frame is too far or too close to the eye, it will affect the eye observation, and there will be a convex looking at the mobile phone.

2. The lens power is not appropriate

If the patient's lens power and eye power are not appropriate, resulting in inaccurate optometry, astigmatism axis deviation, then it will cause a convex looking at the mobile phone.

3. Astigmatic axis tilt

If the patient's astigmatism axis tilts, resulting in a long adaptation process, so there will be a convex looking at the mobile phone.
