How to Choose and Buy a Prescription Mask

For divers and snorkellers who wear glasses, our prescription dive masks provide the ideal solution to correcting your vision underwater. With a custom prescription lens fitted into your chosen dive or snorkel mask, you’ll enjoy a clearer and more focused underwater experience.

While prescription lenses for dive masks come with more design limitations than standard eyeglasses, we offer a range of corrections that will help you see clearly underwater:

• Minus (near-sighted) lenses: Available from -1.0 to -8.0
• Plus (farsighted) lenses: Available from +1.0 to +4.5
• Bifocal lenses: Available in +1.0 to +4.5, for masks that support bifocals

Our prescription lenses are custom-fitted into your chosen mask and we thoroughly test the seals to ensure there is no water leakage. As these lenses are an integral part of the mask, they cannot be returned or exchanged once fitted, so it’s important to double-check your prescription and get in touch with us if you have any questions before placing your order.

How to Build Your Prescription Mask – Detailed Instructions

Follow these steps to create your custom prescription mask:

Step One: Choose Your Mask

 

1. Visit the Mask Builder Page:
   Go to the Prescription Mask Builder page on our website.

2. Browse Available Masks:
   Browse our selection of masks, and choose the one you like. We offer a variety of styles, so there’s something for everyone, whether you’re looking for a sleek design or a mask with specific features.

3. Select Your Mask:
   Once you find your preferred mask, click on it to begin customising. This will take you to the mask builder, where you can start adding your prescription lenses and other preferences.

Step Two: Choose Your Prescription Lenses and Mask Colour

1. Choose Your Mask Colour:
   After selecting your mask, pick the colour that suits your style. This could be any standard colour or a more specific finish, depending on the options available for the mask you’ve selected. We also offer clear silicone and black silicone options - clear is a great option for snorkelling and allows a lot of ambient light in whereas experienced divers, dive professionals and underwater photographers prefer black silicone as it enables them to have tunnel vision and focus.

2. Enter Your Prescription:
   At this point, you’ll need to enter your left and right eye prescriptions. You can find this information on the prescription slip provided by your optician.

   Typically, a prescription will look like this:
   Sph Cyl Axis
   R +1.25 -0.75 120.0
   L +0.75 -0.75 35.0

   For our mask builder, we only need the spherical (Sph) readings. In the example above:

   • Right eye (R): +1.25 = Right +1.5
   • Left eye (L): +0.75 = Left +1
     
     

3. Choose the Correct Lens Power:
   Our lenses are available in increments of 0.5, so if your exact prescription is not available, you’ll need to choose the closest available correction. For example, if you have +1.25 for one eye and +0.75 for the other, you would select the closest matching power from the options provided. And as a rule if you are opting for a plus lense and have say +0.75 you would round up to +1 but if you are opting for a minus lense and have say minus 1.25 you would subtract the .25 leaving you with minus 1.

4. Lens Selection – Left and Right Eye:
   In the mask builder, you will select your left eye and right eye prescriptions individually. Here's how: Left Eye: Use the dropdown to select the left-eye prescription (e.g., +1.0, +1.5, etc.). Right Eye: Similarly, choose the prescription for your right eye.
   
   
5. Select Your Lens Type (if applicable):  
   If your optician has recommended bifocal lenses or if you have a specific lens requirement (e.g., corrective for both distance and reading), pls note the bifocal lenses we offer will only have the magnification in the bottom part of the lense - the top part of the lense will be plain glass. These are great if you struggle to see the digits on your dive computer or underwater photographers use them a lot for small digit reading on their camera set ups. If you wanted to save some money then you can also just choose one bifocal lense say in the left hand side enabling you to read your computer on your left arm. We do not recommend this option but understand that sometimes budgets may be tight. Be aware that bifocal lenses are available for a select range of masks.

Step Three: Add Accessories (Optional)

1. Choose Additional Accessories:
   After selecting your lenses, you’ll have the option to add accessories to your order such as mask straps, mask case or anti-fog solutions. 

2. Review Your Selections:
   Make sure you review all the details of your custom mask before proceeding. This is the time to ensure that everything, from the mask colour to the prescriptions, is exactly as you want it.

Step Four: Add to Basket and Checkout

1. Add to Basket:
   Once you’re satisfied with your custom mask and lens selections, click “Add to Basket.” You’ll be able to review everything in your basket before proceeding.

2. Proceed to Checkout:
   If you’re done, click “Checkout” to finalise your order. If you’d like to continue shopping, you can add more items to your basket at this point.

3. Provide Special Instructions (Optional):
   During checkout, you can leave any special instructions or notes, such as details on how you want to pair the lens corrections with multiple masks if you’ve ordered more than one.

4. Confirm Your Order:
   After entering your details and confirming your selections, complete your order. We’ll begin crafting your custom prescription mask, ensuring everything is properly assembled and tested before shipping.
