2. Double Vision
There is a specific type of myasthenia gravis that affects mostly the areas around the eyes. It is medically termed as ocular myasthenia gravis. People with this particular type often develop other visual disorders such as double vision or binocular diplopia. Having a double vision is a result of weak muscles around the eyeball that control its glance.
Although it is not a permanent resolution to this issue, covering one eye can cause an immediate correction to the doubling image. It is important to know which factors trigger this symptom from happening such as spending too much time reading, staring at a monitor, driving for long hours, and more.
