A glasses prescription is not the same as a contact lens prescription and cannot be used 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.
Glasses are positioned at about 12 millimetres from your eyes, whereas contact lenses sit directly on the eye surface.
Due to this difference, contact lens prescriptions have specifications that aren't listed on your glasses prescription - including base curve, diameter, and lens brand.
The dimensions and material of a lens can affect its suitability.
