Why does my vision go from clear to blurry?already went to the eye doctor and she said it's cause of dry eye but i put eye drops and it won't go away

Could be : Because of an elevated blood sugar. Dryness can definitely cause this but since you are using eye drops, get your blood sugar.

Persistent blurry VA: Persistent blurry VA can be due to chronic dry eyes (meibomian gland scarring), medications (birth control pills), hormonal changes or diabetes, lens changes (forming cataract); nerve issues (glaucoma); retinal issues (swelling); brain issues (tumor benign or malignant); migraines. See good eyeMD to find out underlying cause.
