Made in Japan.
The Takeyoshi Altitude Master is an 8 base frame construction designed for rigorous outdoor pursuits. The ergonomic form is engineered to aid ventilation and enhance the field of vision whilst protecting the eyes. The temples are shaped to accommodate helmet use, and adjustable nose pads and temple tips provide a secure, customized fit, reinforced by a grade 2 titanium core for added durability. Our signature D+ therapeutic-grade lenses are crafted from a shatterproof polycarbonate compound. The interior surfaces feature anti-reflective and oleophobic coatings, providing comprehensive eye protection while repelling water and oil. D+ Fire Mirror was developed for physical pursuits requiring maximum sun protection. The mirror coating facilitates additional infrared screening. The lens offers 100% UVA/B protection while transmitting 19.17% of visible light and 14.03% of blue light.
This version features our vented lenses made with high-precision and hand finished CNC cutting techniques. Vent cuts are positioned along the upper edge of the lenses creating additional air exchange around the frame—helping warm, humid air escape before it can accumulate behind the lens. This increased ventilation reduces conditions that cause condensation and lens fogging, a principle commonly used in performance eyewear. The cuts serve both as a functional detail and a distinct visual element highlighting the beauty of advanced eyewear technology.
