A word from a former Optician.
Optometrists associated with chain optical stores can be very competent, but they are limited in what they can do. They realize their limitations and would forward you to an ophthalmologist as necessary. My son had Optic Neuritis, a potentially serious issue, that was discovered by an optometrist at Pearle. She, of course, forwarded him to the appropriate doctor, thank God the problem was not of concern.
When ocular (visual) migraines occur in the brain, they should appear in both eyes, though it is commonly perceived as being in only one eye, since the visual effects of the migraine may appear to the left of both eyes or the right of both eyes.
If the effects you see are only in one eye, it's possible (though not probable the way you describe them) to be an issue with circulation to the affected eye.
I suffered with ocular migraines a few times a week for 10 years or so. Mine lasted 45 minutes and occasionally would double to 90 minutes. Other than anxiety afterwards, I never had any lasting effects and I could always look at bright lights.
Dr. Oliver Sax, a neurologist, wrote an excellent book on the topic of variant migraines, written for lay people.
Because you've not had them before and not been evaluated, and because of how short they last, not being typical, I'd mention them to your family doctor or, better still, consult an ophthalmologist as BnotAfraid suggested..
