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

Slightly tricky: Mostly straightforward if there is no astigmatism but a little involved if there is astigmatism. I assume you are ordering lenses online and will need that conversion. 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?

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

Why is my contact lens and glasses prescription different?

Why is my contact lens and glasses prescription different?

Numbers game: Fitting cl is an art form as much as science. When the eyeglass refraction is placed in a cl if the number is large enough the strength of the contact may be different to cause good vision. The fit can also change the numbers. These are called "fudge factors'. The numbers are not as important as the ability to see wella nd comfortably. ...Read more

No: If your glasses prescription changed & you don't update, or if you are wearing glasses with the wrong prescription, thea two won't adversely affect your eye health, but your vision will not be optimally in focus.
