Lutina Photo solves real problems that matter in optical practice.

🌡 The 40°C heat-adaptive technology addresses the most common performance gap in photochromic optics. The P-UV dual-surface protection adds a specification that most lenses cannot match. The HEV filtration built into the Lutina material gives every patient an evidence-based eye health benefit — not a coating, but a material property.

At TOKAI, we build lenses that give optical practices something genuinely worth recommending.

Colour selection in photochromic optics is a clinical and commercial decision, not just an aesthetic one. Each tint in the Lutina Photo range has a defined visual character and specific performance profile:

🐀 GRAY — Natural colour rendering with minimal tone shift. Visual transmittance: 89% / 11%.
🐻 BROWN — Contrast-enhancing, expresses brightness. Strong choice for variable light environments. Visual transmittance: 90% / 13%.
🐟 BLUE — Stylish, adds freshness. Increasingly relevant for patients seeking modern, fashion-forward optics. Visual transmittance: 92% / 21%.
🐢 GREEN — Field colour that harmonises with natural environments. Ideal for outdoor-active patients. Visual transmittance: 90% / 13%.

All four tints are approved for driving and nighttime road use — removing a common objection at the point of recommendation.

👁 High-energy violet (HEV) light is a known contributor to oxidative stress in the eye — accelerating the degradation of macular pigment and depleting the eye's natural lutein levels over time.

Lutina lenses are formulated from TOKAI's proprietary material specifically to address this. By filtering approximately 94% of HEV light, Lutina reduces the oxidative load on the eye — helping preserve lutein and support long-term macular health.

Lutina Photo adds photochromic adaptation to this protective foundation. The result is a lens that functions as both a reactive optical tool and a preventive health measure.

Most photochromic lenses share a well-documented limitation: tint depth decreases as ambient temperature rises. In summer, the season when UV exposure is highest, standard photochromic lenses perform at their weakest.

Lutina Photo directly addresses this with High Temperature-Adaptive technology, delivering deep, rich colour payoff consistently up to 40°C.

🔍 For opticians, this is a meaningful clinical argument. It means you can recommend a photochromic lens with genuine confidence in warm-weather performance.

High temperatures remain one of the biggest challenges in photochromic lens technology.

With Lutina Photo, Tokai introduces a solution designed to deliver deeper tinting performance even in warm environments up to 40°C, while continuing to adapt dynamically to UV exposure.

Consistent comfort, stable activation and reliable protection, regardless of the weather.

Photochromic performance should remain reliable, regardless of the environment.

Lutina Photo is designed to maintain a deeper and more stable tint, even in high temperatures up to 40°C, a condition where conventional photochromic lenses often show reduced activation.

The result is a more consistent visual experience throughout the day, even under intense sunlight and warm conditions.

Lutina Photo is engineered to go beyond standard photochromic performance.

By filtering high-energy violet light, the lens helps preserve lutein in the eye, supporting long-term visual health. At the same time, it provides comprehensive UV protection, including from reflected light at the back surface.

Designed for real-world conditions, Lutina Photo maintains consistent tint performance even at higher temperatures, ensuring reliable comfort and protection throughout the day.

With the latest evolution of Lutina Photo, Tokai expands its photochromic offering with a wider palette of color options.

In addition to the established grey and brown, the introduction of green and blue further enhances the range, allowing lenses to be tailored not only for visual comfort, but also for individual preference.

Combined with available color variations, this extended palette supports a more personalised approach to vision, where performance and aesthetics go hand in hand.

21/05/2026

Tokai’s Lutina Photo lens contributes to glare reduction and provides protection against ultraviolet radiation, including light reflected from the back surface of the lens.

These characteristics highlight the importance of evaluating lens performance in real-life conditions, where both environmental and optical variables interact continuously.
