FlareFilter combines a didymium glass filter with our proprietary color correction optics to provide a camera filter that blocks the yellow sodium flare without causing a "purple-tint" in images as seen with uncorrected didymium filters.

This 52mm diameter filter is extra large to fit on flagship phones with multiple camera lenses such as the iPhone Pro and Samsung Galaxy. The rubber-lined clip that will not scratch your phone during use.

Our blue anodized-aluminum filter ring is custom made to accommodate the extended filter thickness, enabling the filter ring to work correctly when stacked with other filters such as VND filters and with standard 52mm lens caps.

Tip: For best results, it is recommended to use manual exposure controls on your phone or camera when creating video. Using automatic exposure modes may cause undesirable changes in brightness while filming.

Note: Due to differences between human color vision and digital camera color rendering, VetroSafe's FlareFilter will appear to have a slightly greenish color  when viewed with the naked eye, but has a neutral gray color when viewed through a digital camera. The light reduction from this filter is approximately equivalent to -1.0 F-stop.

One Lens - Many Uses

Traditional didymium glass lenses reduce sodium flare but cannot be used for high temperature flameworking without layering on additional IR-blocking welding shade protectors. VetroSafe incorporates infrared-blocking as standard in every pair enabling seamless use over a wide range of conditions.

  • Soft Glass

    Even with reduced flame intensity used in soft soda-lime glass flameworking, extended exposure to localized high intensity light can be hazardous. VetroSafe provides comprehensive blue-light filtering and infrared light attenuation in a ground-up lens designed to deliver high brightness visibility for everyday use.

  • Hard Glass

    Borosilicate glass flameworking and fabrication of large workpieces take torch intensity to high levels, necessitating additional protection from invisible infrared light. VetroSafe exceeds ANSI 87.1 Welding Shade #3 protection to provide continuous protection across a wide range of glass types and work size without switching eyewear.

  • Glassblowing

    Furnaces used in glassblowing range between 1000 to 2000 degrees Fahrenheit and pose a significant ocular infrared light hazard even under relatively short exposure conditions, leading to potential for development "glass blower's cataracts". VetroSafe R4-rated lenses block an average 95% of near-infrared light between 780nm to 2000nm.

  • Welding Shade #3

    U6L3R4-rated lens exceeds ANSI Z87.1-2020 W3.0 with R4 95% average infrared light blocking to ensure adequate IR protection regardless of torch intensity and glass type.

  • True Color Vision

    Advanced color corrected lens design with chromaticity white-point less than 0.01 xy units from neutral enables accurate color checking without interrupting workflow.

  • Sodium Flare Blocking

    Precision wavelength-selective OD5+ sodium flare filter removes yellow light in torch flare for a clear view of the work piece during flameworking.

  • Blue-Light Filter

    Advanced 420nm HEV blue-light filter passes good blue-light while eliminating harmful blue-light for reduced eye strain and prevention of macular degeneration.

  • Z87+ Impact-Rated

    Lens and frame made with lightweight industrial-strength high-impact plastic for maximum eye protection from every angle.

  • AR Super-Hydrophobic

    Ophthalmic grade anti-reflection, super-hydrophobic and oleophobic coatings provide maximum visual clarity and an ultra low friction, easy-to-clean lens surface.
