Dailies Contact Lenses

Can I use my contact lens prescription values for eyeglasses?

My contact lens prescription contains all the information I need. My only question is, how significant a difference is there between the values for contacts and eyeglasses for the same person? If you have a prescription for both, how much do the values vary?

1. My contacts and glasses have always been exactly the same prescription. If you are getting a new pair of glasses and you are not getting them from the eye doctor that gave you the prescription - they might want you to have a prescription specifically for glasses and not just contacts.
2. Sometimes the glasses and contact prescription is the same and some times it is not. It is best to get one for both. The glasses is sometimes a bit stronger than that of the contacts.
3. no, you cant. not only will the optician refuse to fill a "contact lens" Rx with glasses, they're different from each other. a CL Rx is "vertexed", which means adjusted for the distance from your eye to the lens (zero). a glasses Rx is not vertexed. plus most glasses Rx's are much more specific...ie -0.25 diopters of astigmatism at 23 degrees...contact lens Rx's cannot be that close.
4. my glasses perscription is actually -.25 less than my contacts
5. you need to be measured for contacts if you didn't have this done.  You always see better with glasses.  Even the founder and former President of Con-Cise contacts, the largest contact manufacturer in the US wears glasses.
