Dear madam, Looking at your history of seeing something moving in front of one eye may be due to dryness of eyes, any debris in the LASIK flap, sutural cataract
after shadow or any vitreous floater
.Since it is changing with blinking there are high chances of dry spots forming in cornea
which is creating an after shadow.Try some lubricating drops like refresh tears for few days and if it still persist then go to your ophthalmologist for complete evaluation with dilated fundus examination too to rule out any breaks or tears in peripheral retina
....Don't worry for now...TC..bye..DR Ajay Shankar Kar,cornea consultant, Sankar foundation eye hospital,Vizag.
