What side effects did contact lenses have at first?

1, mild foreign body sensation: but no pain, no other abnormal phenomena. It may be that the wearer is not used to the edge of the lens. You can keep wearing it, and the symptoms should go away soon. Mild dry eye: the tear film of glasses is affected by the existence of lenses. You can gradually extend the daily wearing time (such as wearing glasses on the first day 4

Hours, wearing glasses for 6 hours the next day, and so on);

2. Mild hyperemia of eyes: but there is no other discomfort, which may be a normal reaction of conjunctiva to the initial adaptation of contact lenses and should disappear within a few days;

3, sometimes blurred vision: when wearing contact lenses for the first time, due to the reduction of involuntary blinking times, it will cause tear film instability, leading to unstable vision, which is normal. It is recommended to maintain a normal number of blinks during wearing. Generally, after short-term adaptation, vision can gradually stabilize;

4. Difficulty in near vision: The accommodation power of contact lenses is different from that of frame glasses, and the accommodation power of contact lenses is greater than that of frame glasses; If it is mild myopia, you can adapt slowly. If you can't adapt, you should replace the low-grade lenses.
