Lens Scratches Can Cause Astigmatism

Adults usually don't change their glasses for a long time. If it is not properly stored, the lens has scratches. If it is in the center of the lens or the area of the scratch is large, it will affect the vision, the eye is also prone to fatigue, and may even cause astigmatism. It is recommended to replace the lens at this time. Of course, if the scratches are small and do not interfere with sight, the problem is not big.
