Are eyeglass lenses all the same?
Prescription glasses can have lenses made from a wide variety of lens materials each differing in refractive index, specific gravity, Abbe number, and other technical mumbo-jumbo. Ask your eye care provider what lens materials they recommend, why, and what benefits they’ll provide for you.
Are glasses lenses universal?
You can put old lenses in new frames in most cases, as long as the new frames are the same ones you used to have. An eye care professional will just need to make sure your prescription doesn’t restrict the type of eyewear you use so that you don’t have issues down the line.
Do all contacts have the same prescription?
Contact lens and glasses prescriptions are not the same. A contact lens must match the size and shape of your eye. Therefore, a prescription for contact lenses contains information like base curve and diameter, as well as brand. However, contacts must be designed to fit the astigmatism, if there is one.
