What if my Lens Strength is not listed in the variants?

Available Strengths:

  • Our lenses are available in increments of 0.50 diopters. If your specific lens strength is not listed, it means we currently do not stock that strength.
  • Different masks have different strength options and availability, so please check the product details for each mask.

Contact Us:

  • If you need different strengths for each eye or have specific requirements, please contact us before placing your order. You can add a note in the cart during checkout, send us an email, or message us on the chat.
  • We're continually sourcing new products and variants, so it's always worth inquiring about your needs.

If you have any questions or need assistance, our customer service team is here to help you find the best solution for your underwater vision needs.
