Can I use my glasses prescription to purchase contact lenses?

Although your glasses and contact lens prescription both correct common eyesight conditions, they may not give you the same level of vision.  

A glasses prescription is not the same as a contact lens prescription and cannot be used to purchase contact lenses. 

Here’s why: 

Glasses are positioned at about 12 millimetres from your eyes, whereas contact lenses sit directly on the eye’s surface.

Due to this difference, contact lens prescriptions have certain specifications that are not listed in your glasses prescription - including base curve, diameter, and lens manufacturer
