An Optometrist can, of course, be male or female, and they are responsible for keeping your eyesight in good shape. They are there to examine and diagnose your eyes, as well as give sufficient treatment to correct poor eyesight. This treatment isn't a bottle of "good-eye" pills, or a needle full of eyesight, it is vision correction throught the use of lenses and other optical aids. Glasses and/or contact lenses are the norm for perscriptions by doctors in the field of optometry.
Now I know there are a few readers out there who are thinking "These eyes are mine! I'm not trusting them to some 'doctor' who can harass me with medical jargon" Luckily, I have your solution... Learn it yourself! No, I'm not saying that I have just found the lost book "Optometrist Medical Jargon for Dummies", there will be some work required. If persuing a carrer in eyesight suits yours interest, there is many institutions to study it. In Canada you can learn about eyes at the University of Montreal (Quebec), or the University of Waterloo (Ontario). In the United States you many more options such as the University of California (Berkeley), the University of Houston (Texas), or the Michigan College of Optometry at Ferris State University.
The field of Optometry is massive, and one can get involved easily. make sure you make a quick visit every so often to make sure your eyes are holding up, and you should be good to go!
