Finding Goggles That Fit
The most important feature in swim goggles: fit. A goggle that leaks — even slightly — destroys your concentration and requires constant adjustment. Fit the goggle against your eye socket before pulling the strap around your head. If it doesn't create a vacuum seal on its own (one second of mild suction), try another model.
Pool vs Open-Water Goggles
| Feature | Pool Goggles | Open-Water Goggles |
|---|---|---|
| Lens size | Small (low drag) | Large (wide peripheral vision) |
| Lens color | Clear or smoke (indoor light) | Mirrored, smoke (outdoor sun) |
| Gasket | Tight, minimal | Wider, more comfortable for long wear |
| Fit pressure | High (competitive) | Lower (endurance comfort) |
| Best for | Lap swimming, training | Open water triathlon, marathon swimming |
Lens Types
- Clear: Best for indoor pools with overhead lighting. Maximum light transmission.
- Smoke/tinted: Reduces glare for outdoor pools and overcast open water.
- Mirrored: Best for bright sunny open water. Reflects sunlight from water surface.
- Polarized: Cuts water reflection — best for open-water swimming direction finding. Premium option.
- Blue/yellow: Blue reduces glare in varying light; yellow enhances contrast in low light.
Anti-Fog Technology
All quality swim goggles have factory anti-fog coating. This coating degrades with use — typically 60-100 swims. To extend coating life: never rub the inside of the lens with fingers (oils degrade coating), rinse with cold fresh water after each swim, store in a case away from direct sun.
When coating fails: apply anti-fog spray (McNett Sea Buff) or use the classic "spit" method. Avoid toothpaste inside the lens — scratches the coating.
