Blur and Distorted Vision
can be a signal of underlying eye or brain disease
Blurred and distorted vision
Blurred vision can similarly come from the eye or brain.
It may take an ophthalmologist or neuro-ophthalmologist to distinguish between diagnoses and determine whether the condition is harmless or sight or life threatening..
Cataracts cause blur without much
distortion. As they develop they can cause rapid changes in
your spectacle prescription. If you think that you are
having frequent changes to your glasses,
ask your optometrist if its due to developing cataract as
this may need to be addressed first.
Simple refractive errors and astigmatism similarly cause generalised blur.
