How to Buy a Prescription Mask

Prescription masks give divers and snorkellers that wear glasses the option of fitting corrective lenses into a selected range of dive masks, allowing them to see and experience the underwater world in significantly better focus and clarity.

Mask prescription lenses don't come in as wide a choice as prescription glasses due to the design limitations of masks and their lenses but corrections are normally available in -1.0 to -8.0 in minus corrections and +1.0 to +4.5 in positive corrections. Bifocal lenses ranging from +1.0 to +4.5 corrections are also available on a more select range of masks.

As these are replacement lenses rather than stick on or self adhesive lenses we assemble the lenses into the mask for free and fully test the seals before orders are shipped to ensure there will be no water leakage. Please note that once fitted the lenses are non-refundable so please contact us if you have any questions or require any further assistance before placing your order.

If you already have a mask that you would like corrective lenses fitted into you can always send the mask to us. We will then assemble the mask and lenses, test and send the mask back to you. Please contact us if you would like to take advantage of this service.

We also now offer a bespoke prescription lenses service which will custom produce a pair of lenses to your exact prescription designed to fit a twin lens mask of your choice. If you have a larger cylinder value or complex prescription this service will result in a superior correction compared to off the shelf replacement lenses.


Step One; Choose Your Mask

Browse our range of Prescription Masks for one you like, choose your desired option / colour where appropriate and add it to your basket so that it is ready and waiting.

Further down the page in the description you will find links to the available lens corrections. Click on the link that matches your correction needs (minus, plus or bifocal) to be taken through to choosing your prescription lenses and move on to Step Two.

Step Two; Choose your lens correction

Lens corrections are based on your spherical reading and can be found on the glasses prescription obtained from your optician. Typically it will look something like this:

  Sph Cyl Axis
R +1.25 -0.75 120.0
L +0.75 -0.75 35.0

We are only interested in the spherical reading (sph) which in this case is +1.25 in the right eye and +0.75 in the left eye. Unfortunately lens correction are typically only available in increments of 0.5 so you will need to opt for the closest lens correction. Please don't hesitate to ask us if you are unsure about the best correction to choose.

Here you will need to add TWO lenses to your basket (unless you only need a correction for one eye of course). Prices shown are per lens so with lenses starting at around £26 your of two corrective lenses will start from £52 in total. Make sure you add both lenses by checking this step by step guide:

  1. Choose Left from the 'side' dropdown menu
  2. Select your left eye correction
  3. Click 'Add To Cart' to save you selection in the basket
  4. Choose Right from the 'side' dropdown menu
  5. Select your right eye correction
  6. Click 'Add To Cart' to save you selection in the basket

Your mask and lenses are now safely stored in your basket and you can move on to Step 3.

Step Three; Checkout

Once you have finished adding everything you want to order to your basket you can continue on to the checkout and start the completion process. Here you can add any useful instruction that we need to follow that will help us fulfil your order as quickly as possible like which corrections go with which mask if you are ordering two of the same mask but in different colours.

If we have any questions regarding your completed order we will contact you promptly. Remember to contact us or come into the store and speak to us if you have any questions about ordering your prescription mask and corrective lenses.
