What would you suggest I do to convert my glasses prescription to contact lens prescription?

There is also some experience functions depending upon the type of lens. Check with your ophthalmologist to get this done for you. Optometrists are unlikely to do it as they prefer to sell you lenses. ...Read more

My contact lens prescription is different from my glasses prescription. Is it supposed to be like that?

Yes: The optical principle is lens effectivity. As any lens is moved away from your eye it becomes inherently more powerful (positive) the inverse is also true, as a lens is moved to eye, becomes weaker (negative). So contacts and glasses are adjusted accordingly only if it will affect the final clinical outcome. ...Read more

Depends: If your vision has changed since the last time you got glasses, you'll certainly want to be examined to get a new prescription.
