Frequently Asked Questions

ClearLens is a free contact lens price comparison engine. We help you find the best deals by comparing prices across multiple online stores in real time. We do not sell lenses directly; instead, we redirect you to trusted partner retailers.

Our automated algorithms regularly scan and update pricing, discounts, and availability directly from major retailer websites, providing you with objective and up-to-date information without any markups or hidden fees.

Yes, ClearLens is completely free for users. We do not charge any commission for comparison or store redirection. The project is funded through minor affiliate partnerships (referral commissions from stores), which do not affect the price you pay.

Our mobile app is your personal companion for healthy lens wearing. It tracks wearing hours, maintains a replacement calendar (for daily, bi-weekly, or monthly lenses), and sends push notifications to help you avoid overwearing and keep your eyes healthy.

The app is currently in active beta testing for Android. You can submit your email on the homepage or under the "Get Mobile App" section, and we will send you an invite for the Google Play Beta Test. The iOS version is scheduled for release in August 2026.

Prices are updated in real time, but temporary discrepancies may occur due to caching or sudden price updates on the merchant side. If you notice a price mismatch, please let us know at clearlenssupport@gmail.com.

We only partner with established, certified online optical stores that sell genuine products. All purchase transactions and payments happen securely on the retailers' websites. ClearLens does not collect or store your payment details.
