Yes, but there is something more going on. Long term strabismus usually
doesn't cause nausea and severe dizziness. That sounds more like vertigo.
Most people with neurological disorders have some kind of vision disorder
even if acuity is normal, they may have all sorts of trouble with
interpreting visual input. However, there is also a high incident of
vestibular issues also due to the underlying neurological disorder. This is
why consults with a good neurolo opthamologist and a good ENT are in order.
3-D glasses don't work for me either and with the wrong glassess stairs
look like bunch of lines to me also.

Lots of CPers (my self included) have issues with depth-perception due to
strabismus (aka "lazy eye"). If the weaker side eye muscles weren't trained
properly early on, the brain sets up a hard dominance in the stronger eye
and images from the weaker eye are poorly processed. Both eyes need to be
able to simultaneously focus on an object in order to perceive depth
(binocular vision). Everyone has a dominant eye, but those folks with
uncorrected strabismus have a dominate eye that is...well, dominant!
Putting on 3-D glasses for the Godzilla movie does you no good because
you're exclusively looking out of the red or green lense.
So, how do people without depth-perception acquire skills (like driving)
that require the ability to perceive spatial relationships? We have a form
of "learned" depth-perception that allows us to determine where things are
in space through cues such as shading, focus, or known size relativities.
Stairs are a drag if they are evenly lit. You can't tell if you need to
step up or down. It can sometimes appear to be in the same plane.

Mary,
Have you had your eyes check by a neuro- opthamologist lately? What is your
acuity? You actually sound like you have more of a vestibular system issue.
The vestibular system is something of a sixth sense that we don't think
about. It's what lets your body know where you are at and if you are moving
or not (a very quick and simplified explaination). Usually, some kind of
knowledgeable neuro person such as a good ENT, neuro-opthamologist or such
can help you find a reputable vestibular rehabilitation place. Dizzy and
seasick feelings are signs of vertigo. Vertigo is a sign of many different
kinds of disorders and you need a good doc who can help you piece it
together.
