You should replace your swimming goggles when the lenses are too scratched, they are no longer watertight, or at least every 6 months for frequent swimmers.
The lifespan of swimming goggles depends heavily on how often they are used and the conditions they are exposed to. While the ultimate decision on when to replace them rests on the swimmer and their assessment of the goggles' condition, there's a general guideline, especially for those who swim regularly.
Key Indicators for Replacement
Beyond a set timeframe, several signs indicate it's time for new goggles:
- Lenses are too scratched: Scratches impair vision and can make swimming uncomfortable or unsafe.
- Not watertight anymore: Leaking goggles defeat their primary purpose and can cause eye irritation from pool water or saltwater.
- Elastic strap is worn out or stretched: A loose strap prevents a proper seal.
- Nose bridge is damaged or ill-fitting: This also affects the seal and comfort.
- Anti-fog coating has completely worn off: While some coatings can be reapplied, excessive fogging can be a sign of aging lenses.
Replacement Frequency Guidance
According to swimming guidance, frequent swimmers will need to replace their swimming goggles at least every 6 months. This recommendation exists because external factors inevitably degrade the materials over time.
Why the timeframe?
- Chlorine and sunshine break down the materials no matter how carefully you care for them. Exposure to pool chemicals and UV rays causes plastic, silicone, and rubber components to stiffen, crack, and lose elasticity, compromising the goggle's seal and comfort.
Factors Affecting Goggle Lifespan
The "at least every 6 months" guideline is a minimum for frequent users. Less frequent swimmers might get more life out of their goggles, while competitive swimmers training multiple times a week might need to replace them sooner if they show signs of wear.
Here's a simple overview of factors influencing how long goggles last:
| Factor | Impact on Lifespan |
|---|---|
| Frequency of Use | More use = shorter lifespan |
| Water Type | Chlorine/Saltwater accelerate material breakdown |
| Sun Exposure | UV rays degrade materials |
| Care & Storage | Proper care extends life; poor care shortens it |
| Goggle Quality | Higher quality materials may last longer |
Extending Your Goggles' Life
While replacement is eventually necessary due to material breakdown, you can help your goggles last as long as possible by:
- Rinsing them with clean, fresh water immediately after each use to remove chlorine or salt.
- Allowing them to air dry completely before storing.
- Storing them in a protective case to prevent scratches.
- Avoiding touching the inside of the lenses to preserve anti-fog coating.
By paying attention to the condition of your goggles and following the recommended timeframe for frequent swimmers, you can ensure comfortable, clear vision in the water.
