Frequently Asked Questions


Are contact lens and eyeglass prescriptions the same?

Contact lens prescriptions and eyeglass prescriptions are not the same. They are significantly different because eyeglass lenses are positioned approximately 12 millimeters from your eyes, whereas contact lenses rest directly on the surface of your eyes. The power of a contact lens will be slightly less nearsighted or slightly more farsighted.


How can I order if my eyes have different powers?

Two lenses are packed into one box in the production line. If you need independent powers for either eye and both powers are available, you may consider buying pairs of both powers and mixing them before use. Check out our active promotion offers on this page and redeem codes accordingly during checkout. Plus our lenses feature prolonged shelf life and can be stored for a long time when unpacked.
