Swim and diving goggles prescription
Good vision underwater makes a big difference. Whether you swim laps in the pool, snorkel on vacation or dive in open water: with prescription swimming or diving goggles, your underwater vision is sharp and relaxed again. You no longer have to peer or rely on blurred outlines, but can simply enjoy clear vision while swimming or diving.
For many people with glasses or contact lenses, swimming without correction can be difficult. Contact lenses can wash out or cause irritation in the water, while ordinary glasses are obviously not suitable for use in the water. A pair of prescription swimming or diving goggles offers a practical and comfortable solution. We also offer special goggles that fit under a diving or full-face mask.
Why choose prescription swimming or diving goggles?
With prescription glasses, you can see sharply again underwater. This makes swimming not only more comfortable, but also safer. You can clearly see where you are swimming, navigate better and more easily recognize other swimmers or objects in the water.
For snorkelers and divers, good visibility also makes for a much better experience. Details of fish, coral and underwater structures become visible, allowing you to experience the underwater world much more intensely.
Different strength options
Swim and diving prescription glasses are available in a variety of designs. Many models work with separate lenses per eye, making it easy to adjust the strength. This is ideal when you have a different prescription on the left and right.
For people with a more complex correction, such as cylinder strength, there are also custom solutions where the lenses are made especially for your eye strength. This way, even with a higher prescription or astigmatism, you can continue to see sharply under water. all this can be easily put together yourself.
Comfort and good fit
In addition to the prescription, the fit of the goggles is also important. A good pair of swimming or diving goggles fits comfortably around the eyes and prevents water from entering. Soft silicone seals provide a comfortable seal without pressure points.
Many models have adjustable straps and a flexible frame so that the goggles stay in place while swimming, diving or snorkeling.
Clear vision and protection
The lenses of swimming and diving goggles are made of tough, clear material that can withstand use in water. Many models also have an anti-fogging coating that helps reduce fogging.
When used in outdoor water or on vacation, a light tint or UV protection can be nice. This will also protect your eyes from bright sunlight when swimming or snorkeling on the surface.
Advice for the right swimming or diving goggles
The right swimming or diving goggles depend on your strength, type of activity and personal preference. Swimmers in the pool often have different needs than snorkelers or divers who are underwater for longer periods of time.
At Specialspex, we are happy to help you choose a pair of prescription swimming or diving goggles that fits properly and provides the best vision. So you can with confidence and comfort in the water
Frequently asked questions
A commonly used rule of thumb is:
Spherical power + half of the cylinder = the power for the swimming or diving goggles.
Example:
If you have a prescription of ‑2.00 with a cylinder of ‑1.00, you add half of the cylinder (‑0.50) to the spherical power. The power for your swimming or diving goggles then becomes approximately ‑2.50.
Because most swimming goggles are available in 0.5 steps, you usually choose the closest available power. For many swimmers and snorkelers, this approximation works very well.
If you have a cylinder stronger than ‑1.00 or want the sharpest possible vision underwater, a custom‑made swimming or diving mask with full correction may be a better solution.
There are several options. If you do not need distance correction, you can choose a diving mask with standard lenses that include only a reading section. This way, you maintain normal distance vision while having extra support for near vision.
In addition, fully custom-made solutions are also available. In this case, the lenses are produced exactly to your prescription, and the reading section can be made larger and positioned precisely where you need it. This provides greater comfort and better visibility when viewing instruments or fine details underwater.
However, it is possible to include different prescriptions in a diving mask. For example, distance correction can be placed in the lenses, combined with a separate reading section for close-up vision. This allows you to see clearly in the distance underwater while still being able to read your dive computer or instruments.
Another option is a special pair of glasses worn underneath the diving mask. These underwater glasses can easily be fitted with multifocal lenses, allowing you to see clearly both far away and up close while diving.
Additionally, it can sometimes be a bit harder to detect very light wind gusts on the water’s surface. Polarization filters reflections from the water, while sailors often rely on subtle reflections or sparkles to spot light wind movement. Because these reflections are reduced, such small changes can be less noticeable. For most sailors, however, the benefits of reduced glare and improved contrast far outweigh this minor effect.
