Well, in my opinion, for strabismus, it will be fine to have optometrist to detect it. And first, you should know that strabismus are the medical terms for eye conditions commonly called eye turns, crossed eyes. For the symptoms, eyestrain, blurry vision, double vision, and headaches can be very common ones. To cure it, of course, surgery is essential. At the same time, patches and corrective glasses will be effective too. By the way, for the causes, strabismus is typically caused by injury to the eye orbit, injuries to the brain. So just pay more attention to your eyes.
