Get started with our free online trial offer – 10 pairs of Basis contact lenses for free, just pay $4.99 for shipping. To take advantage of this trial, you’ll have to enrol in a Basis subscription, which will kick-in 14 days after the trial. You’re in complete control over your plan and you can edit or cancel at any time, or stop the subscription and buy ala carte on our product page if you prefer!

If you need a prescription or would like to check your eyes first, you can come by The Studio for a free eyetest anytime, which comes with 4 free trial pairs. It’ll only take about 15 mins of your time, or 30 mins if you’ve never worn lenses before.

Do note that the free online trial offer is limited to first-time customers who have not previously received trial lenses, including the ones received at The Studio after consultation.

Basis is not a toric lens (i.e., not designed specifically to correct astigmatism), but your optometrist can  check your eyes and make calculations to get you the best possible vision without astigmatism correction. If your astigmatism is low (CYL -1.00 or below), there’s a good chance our Basis lens will work for you.

Definitely seek advice from a qualified optometrist, or visit us to find out if you’re suitable for non-toric lenses. Eyetests at the Studio are free →

Please note that spectacles prescriptions are different from contact lens prescriptions. If your spectacle spherical power is above ±4.00, your contact lens power should be lower. You can find your contact lens prescription printed on your contact lens box or on the blister foils. If you have a CYL (Cylindrical) component in your contact lens prescription, they are written for toric lenses, and not suited for Basis.
