Many are wearing prescription contact lens and eyeglass to improve eyesight. And a common question is: Are contact lens and eyeglass prescriptions the same?
The answer is they are NOT the same. They are significantly different because contact lenses rest directly on the surface of your eyes while eyeglass sit approximately 12 millimeters from your eyes.
Depending on the refractive error and the strength of lens required to correct it and the type of contact lens you need, the parameters specified on your glasses prescription may be significantly different from those on your contact lenses prescription.
If you want to wear both contact lenses and eyeglasses, you will need two separate prescriptions.
What are Toric contact lenses? What’s the difference?
Toric contact lenses correct for astigmatism issues that arise from a different curvature of the cornea or lens in your eye (referred to as regular astigmatism, corneal astigmatism or lenticular astigmatism).
A toric lens is a contact lens that's shaped in a particular way, they have a more complex design. Standard contact lenses have a spherical surface (typical rounded design).
Toric contacts need to be prescribed by your doctor, who can choose the lenses that are right for your vision, and fit them for your eyes. Talk to your eye doctor if you think you need contact lenses for astigmatism or other vision problems.
