Retin-A Causing Vision Loss?

Retin-A that gets into the eyes inadvertently can cause a bit of irritation (or a lot, depending on the amount!) which can lead to corneal swelling, which in turn distorts vision slightly, just as a Lasik procedure uses a laser to shape the cornea to distort vision in a "positive" direction.

Stop getting it in your eyes and the irritation will resolve, the swelling will normalize, and your vision will be the same as it was before the Retin-A exposure. You don't need to stop the Retin-A, you just need to use less or be more careful (or perhaps not rub your eyes in your sleep).

Retin A can irritate the eyelids especially in the winter when the skin is dry to begin with.
In addition if Retin A gets into the eye, there will be irritation as well that may cause blurry vision.
Stopping the Retin A should resolve the blurriness.
Consider also that when a moisturizing cream may cause blurry vision if it gets into the eye.
Finally, there are causes of blurry vision outside of Retin A and moisturizers. If the blurriness does not improve after a few days, a visit to an ophthalmologist is in order.

It seems unlikely that you could suffer permanent blurry vision as a result of retin-a use around the eye.  I would suggest that you stop use of the retin-a completely until the vision issue resolves.  Because use of retin-a around the eye predictably causes redness, irritation and peeling, I will usually suggest that a thin layer of moisturizer be applied first and just a very small amount of retin-a be applied on top.

Retin A can be used around the eyes as long as you are careful not to get it into the eyes. If it does, it will irritate since it is not formulated for the eyes. If it gets in, however, it will irritate the eyes and perhaps cause a chemical conjunctivitis. This should not, however, cause vision loss. PS Renova is preferred for wrinkles anyway. Retin A too drying.
