Swimming Goggles: What Specs Really Matter?
Learn how to read goggle specs and choose the right pair for your swim session.
Published · 2 min read
When shopping for swimming goggles, it's easy to get lost in a sea of specifications. But not all numbers tell the whole story. Here’s what you really need to know.
The Seal, Not the Strap, Keeps Water Out
- The gasket is crucial for a good seal, not just the strap. A well-fitting gasket ensures water doesn’t leak in.
- A poor seal means water can get inside, no matter how fancy your strap is.
Lens Tint: About Light, Not Looks
- Choose a lens tint based on lighting conditions. Bright sunlight calls for mirrored or polarised lenses.
- Smoke tints are good for general use but won’t help in bright conditions.
Fit Hardware: Nose Bridge and Strap
- Nose bridges come in fixed or adjustable varieties. Find one that fits snugly but comfortably.
- Split straps distribute pressure evenly across the back of your head for a secure fit.
Pool vs Open Water vs Children
- Swim masks are designed to cover more area, making them better for open water where the goggles might not seal as well.
- Children's goggles often have a softer fit and smaller lenses.

Frequently asked questions
Do mirrored and polarised lenses make a difference?
Mirrored lenses reduce glare in bright conditions, while polarised lenses filter light reflecting off water surfaces.
How do I know if my goggles will fit well?
A good seal comes from the gasket more than the strap. Try different nose bridges and split straps to find what fits you best.
Why are prescription swimming goggles not ideal for everyone?
Prescription goggles provide an approximate correction but don’t address astigmatism, making them less precise than standard lenses.
Can I fix a worn-out antifog coating?
Regular cleaning can help extend the life of your antifog coating. Once it’s rubbed off, you may need new goggles.
