Is the blurry vision from Botox reversible? Will it go away?

If the glasses correct the blurry vision, it sounds like it's not related to the Botox injections since neurotoxins won't change a prescription (probably coincidental).  If injections are very close to the eyes, sometimes they can weaken the orbicularis muscle (which causes the eye to close) and patients can get a dry eye or even a droopy lower eyelid.  The dry eye can contribute to blurry vision but that wouldn't be correctable with glasses and would resolve as the effect of the botox wore off.  Botox can affect eye movement if it is injected near one of the eye muscles but that would result in temporary double vision rather than blurry vision.Hope that helps.

It is unfortunate that Botox injections cause headaches for
you.This is a relatively uncommon side
effect, but it is usually only temporary.Less than 1% of patients may develop severe, life-altering headaches
that can persist for 2-4 weeks.The
cause of these headaches is unknown.However, the headaches are not typically associated with blurry vision.Are you having blurry vision or double vision?Double vision is a rare complication of Botox
injections that occurs when the Botox diffuses to the extraocular muscles.These muscles are responsible for eye
movements, and paralysis causes a condition called strabismus.It is important to see a board-certified
ophthomologist as soon as possible so that an accurate diagnosis can be
made.Strabismus is usually temporary,
and temporary treatments can help with symptoms until the extraocular muscles
regain normal function.An
ophthalmologist may recommend an eye patch or a Frensel membrane prism in your
eyeglasses, and you will need to be seen on a regular basis to monitor for
resolution of the condition.
