I had blurred vision from my left eye. i went to the eye doctor (dilated pupils) and everything is healthy. it has happened twice. can this be ms?

Ask for a referral: Ask your eye doctor if it is possible to have a referral to a neuro-ophthalmologist, or to a university eye clinic.

Yes.: You could go to a neuro-ophthalmology specialist. Another option that may be more available would be to see a general ophthalmologist. Regardless, the diagnosis of ms (multiple sclerosis) is based upon a variety of factors. It is not uncommon for it to take some time to make the diagnosis. Many patients are monitored for ms but never develop full blown disease.

Doubtful: Transient blurring of vision is NOT consistent with MS, unless you already have the disease, and prior damage to optic nerve, with exposure to heat perhaps. Rather consider effect of decreased blood flow (TIA), or perhaps, migraine issues. Both need to be ruled out.
