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.

The performance of photochromic lenses is directly influenced by environmental factors such as ultraviolet intensity and temperature.

Lutina Photo Version 2 has been developed to overcome a known limitation: reduced color density at higher temperatures. By maintaining a deeper tint even in warm conditions, the lens ensures reliable performance throughout the day.

Protection today goes beyond traditional UV filtering. Lutina Photo blocks not only ultraviolet light, but also high-energy violet light, a specific part of the spectrum associated with oxidative stress in the eye. Combined with stable tint performance in varying temperatures, the lens contributes to a more comprehensive approach to eye care.

What makes Lutina Photo fundamentally different lies in its material.

Built on Tokai’s proprietary Lutina technology, the lens is designed to protect lutein, a key pigment in the eye that plays a role in visual performance and long-term ocular health. By filtering high-energy violet (HEV) light, Lutina helps reduce oxidative stress while maintaining stable performance across varying environmental conditions.

With the latest evolution of Lutina Photo, Tokai introduces two new color options: blue and green.

Each color is designed to offer a distinct visual experience, supporting contrast perception and comfort in different environments. Combined with Lutina’s advanced light filtering and consistent performance, even in higher temperatures, these new options allow for a more personalised approach to vision.
