Stains on glass lenses or glas domes

Maintaining Underwater Glass Lenses: A Guide to Prevent Stains and Ensure Longevity

Underwater photography relies heavily on specialized equipment, and one of the most critical components is the glass lens. These lenses, crafted from low-dispersion optical-grade glass, offer exceptional clarity and performance when diving with them in front of your camera lens. Enhanced with anti-reflective coatings, these wet-lenses minimize optical challenges such as chromatic aberrations, spherical aberration, and field deformation, ensuring good underwater macro photography results. Housed in rugged, anodized aluminum casings and nitrogen-purged to prevent fogging, these lenses are built to withstand the harsh underwater environment. However, proper maintenance is essential to preserve their performance and lifespan.

Why Proper Maintenance Matters

Despite their robust design, underwater lenses are vulnerable to staining if not cared for correctly. When water – even fresh water – dries on the glass surface, it can leave mineral deposits and stains that are difficult to remove. These deposits can interfere with the lens coatings, compromising the image quality and potentially damaging the glass over time. To keep your lenses in pristine condition, it’s crucial to adopt an effective cleaning routine.

If your glass lens has been stained, it is unlikely you can clean the glass again.
You then need to get the front lens changed.

Best Practices for Cleaning Underwater Glass Lenses

  1. Rinse Immediately After Use
    After completing your dive, rinse the lens thoroughly with fresh water. This step removes salt, sand, and other debris that could scratch or stain the lens. Using lukewarm water is particularly effective in dissolving salt crystals. (not too warm, and NO soap must be used)
  2. Dry Completely with a Synthetic Fiber Cloth
    Drying is as critical as rinsing. Use a synthetic microfiber cloth, which is both soft and absorbent, to gently remove all water from the lens. This step ensures no water remains to evaporate and leave behind mineral stains.
  3. Avoid Air Drying
    Never allow water to dry naturally on the lens. As it evaporates, minerals in the water can crystallize on the surface, causing stains and potentially harming the delicate coatings.
  4. Inspect for Streaks or Residues
    Once dry, inspect the lens under light to ensure no streaks or water spots remain. If you notice any, re-clean with a damp microfiber cloth and dry thoroughly.


Pro Tips for Long-Term Lens Care

  • Invest in a Lens Cap
    Protect your lens when it’s not in use by always securing a lens cap. This simple step prevents accidental scratches and keeps debris away from the glass.
  • Store in a Safe Environment
    Store your lens in a cool, dry place, ideally in a protective case. This minimizes exposure to humidity and physical damage.
  • Avoid Abrasive Materials
    Never use abrasive cloths, tissues, or cleaning agents that could scratch or degrade the glass surface.


The Impact of Good Maintenance

By following these straightforward yet effective cleaning practices, you ensure your underwater glass lens remains free of stains and scratches, allowing you to capture clear and vibrant images dive after dive. Proper maintenance not only preserves the performance of the lens but also extends its lifespan, saving you the cost of premature glass replacements. Remember, the key to great underwater photography starts with pristine optics. Take care of your lens, and it will take care of your memories.

If you still get a faulty lens it is possible to exchange the glass. But it is not cheap as the lens is full of nitrogen and needs to get refilled under completely dry conditions.
