Welcome to Just Answer:
Sorry for your eye problem and inconvenience. It is possible that you are experiencing the effect of double vision
and/or blurred vision caused by the imbalance of eye focusing from the high pitched sound irritation
of the inner ear cells leading to intermittent nystagmus
(out of focusing of the eye muscles
or misaligment). Such imbalance can also occur from new onset sudden stress. If there is irritation of the inner ear cells that caused nystagmus and/or double vision in this case, it would generally resolve over 1-2 weeks on it's own. In addition, it is possible that you may also be experiencing sudden change in eye muscles imbalance from natural decompensation (accommodation or convergence insufficiency) requiring new corrective glasses
or eye muscle optotic exercises. Increased life stress can particularly cause eye muscle balance or decompensation with associated poor focusing. In either cases, a follow-up with the eye doctor is necessary for detail eye evaluation to determine the best corrective measure. In the measure avoid driving, using preservative free tear drop such as Genteal tear drop or Refresh plus in each eye 4 times daily and rest more until you see your eye doctor.
