The second tier of the Color Blind Safety Glasses segmentation focuses on types, which are differentiated by optical technology and customization level. Spectral‑filter glasses employ fixed‑wavelength filters to isolate problematic color bands, serving the majority of standard‑issue programs. Polarized lenses reduce glare while preserving color contrast, a niche that benefits outdoor and welding operations. Photochromic glasses automatically adjust tint in response to ambient light, meeting the needs of workers transitioning between indoor and outdoor settings. Within each technology, sub‑categories include standard (non‑prescription), prescription, and custom‑fit models, each adding incremental value through ergonomics and visual acuity correction. Although types collectively account for the full market, the distribution of revenue leans heavily toward spectral‑filter and standard models, which together generate approximately 70 % of sales, while polarized, photochromic, and custom solutions split the remaining 30 % based on specialized functional requirements.
