Single VIsion
Best For:
- Nearsighted (myopia)
- Farsighted (hyperopia)
- Astigmatism
- Divers who primarily need one prescription distance
Single vision lenses provide one prescription throughout the entire lens. This is the most popular option for divers who simply need their everyday distance prescription while underwater.
If you normally wear single vision glasses or contact lenses, this is typically the best prescription option for your dive mask.
SeaVision Tip: Even if you wear progressive glasses every day, many snorkelers choose Single Vision lenses because they offer the most natural underwater viewing experience.
Bifocal Lenses
Best For:
- Divers over 40
- Presbyopia
- Reading dive computers and gauges
As we age, reading small print becomes more difficult. Bifocal dive mask lenses combine your distance prescription with a reading segment located in the lower portion of each lens.
This allows you to:
- See clearly in the distance
- Read your dive computer
- Monitor pressure gauges
- Check underwater cameras
- Read compass markings
Instead of struggling to focus on your instruments, bifocal lenses make it easy to transition between viewing the underwater environment and reading important dive information.
Gauge Readers
Instead of providing a full prescription across the lens, Gauge Readers place a small magnification segment in the bottom corner of each lens. This gives divers assistance only when reading nearby instruments while leaving the rest of the mask unobstructed.
Gauge Readers are ideal if you:
- Already see well at a distance
- Only need help reading gauges
- Wear contacts for distance correction
- Want an affordable reading solution
Many experienced divers appreciate that Gauge Readers provide magnification only when needed while maintaining a natural field of view.
