Step 1: Your Requirements
Contact Lens Product Finder FAQs
Can I use my glasses prescription to order contact lenses?
No. A glasses prescription is different from a contact lens prescription. Contact lenses require fitting details such as base curve, diameter, and sometimes brand-specific information.
What does BC mean on contact lenses?
BC stands for base curve. It describes the curve of the contact lens and should match the details supplied by your optometrist or current lens box.
What does DIA mean on contact lenses?
DIA stands for diameter. It refers to the width of the contact lens and should match your contact lens prescription or current lens box.
What do CYL and AXIS mean?
CYL and AXIS are commonly used for toric contact lenses for astigmatism. If your prescription includes these fields, browse toric contact lens categories and match the exact values before ordering.
What does ADD mean for multifocal contact lenses?
ADD is used for multifocal contact lenses, which are designed for people who need help with near and distance vision. Always match the ADD value supplied by your optometrist.
Can I switch contact lens brands online?
You should not switch contact lens brands or lens types without advice from your optometrist, as lenses can fit and feel differently even when prescription values look similar.
