Our lenses are engineered to selectively filter light and enhance color differentiation while preserving natural visual balance. A Brand Focused on Color Vision Pilestone, proudly a USA brand, was founded in 2011 by Dr. Ben at UPenn to help a color-deficient friend see the world in color. For more than a decade, Pilestone, the original inventor of color blind glasses that work for most types of color blindness, has focused exclusively on color vision solutions. Through continuous refinement, testing, and real-world feedback, we design eyewear that helps users better distinguish colors in everyday life. Our commitment is simple: thoughtful design, consistent quality, and products backed by a brand that stands behind what it creates. How Color-Filtering Lenses Help Color vision deficiencies often make it difficult to distinguish certain shades, particularly along the red-green spectrum. Pilestone lenses are designed to selectively filter overlapping wavelengths, helping improve contrast between colors that may otherwise appear similar. The result is enhanced color separation with balanced visual comfort for daily use. *Results may vary depending on individual vision conditions. Why Choose Pilestone Purpose-Designed Filtering Developed specifically for color vision enhancement β€” not generic tinted lenses. Designed to enhance differentiation while maintaining natural tones. Comfort for Daily Wear Engineered to minimize visual fatigue during extended use. Suitable for everyday activities indoors and outdoors. Trusted Brand Support Backed by a dedicated after-sales team based in the USA. Clear 60-day return policies against manufacture defects.
