It sounds like you are just more aware of things that have likely always been there but are just more noticeable because your brain has lost some ability to ignore these sensations.

It likely has more to do with the tear film on your eye than anything else. I have a tear disorder. When I do an eye test. I get these same disturbances if I blink as I am looking at the eye chart. The letters will distort until the tear film smooths out.

You could try using eye moisturizing drops. I like the drops that contain hyaluronic acid. That is a moisturizing substance often used in skin creams because it helps moisturize human tissues. It is often listed as sodium hyaluronate.
