Is it normal to be able to change my vision from clear to blurry on demand?

Question

I think I worded it badly but I’ll try again here, I can control when my eyes show a clear image and a blurry image, is it normal or harmful? I’ve searched a few places but haven’t found a solid answer. I don’t know if it is from too much time looking at screens or just my eye getting older.

Answer 1

Yes, it is completely normal and called ‘eye accomodation’. It is a process which uses the contraction / relaxation of your eye muscles to change the focal point inside your eye. As a result you can consciously go from sharp to blurry vision.
