Which type of profession is most suitable for people with high degrees of myopia?

Any profession. While persons with high amounts of myopia can have a higher rate of retinal tears or detachments, proper glasses or contacts or lasik should yield 20/20 or better vision. If you are concerned about vision loss, annual dilated eye exams can be reassuring, and a profession that is less likely to require high amounts of visual detail may mitigate this concern as well.
No limitation. High myopia can be corrected. Should avoid professions with traumatic contact to the eyes.
OD or MD. See an eye care professional. They can assess you and make recommendaitons.
