Synchronize your vision with your natural rhythm
Lenses designed to support your natural rhythm from morning to night.
The master switch
You don't just see light. Your body runs on it.
Deep in your eye are cells that have nothing to do with vision: their only job is to tell your brain what time it is. That single signal sets the systems you see here.
Discover the scienceThe right light at the right time supports alertness and motivation. Filtering excess blue light from screens during the day reduces eye strain and helps you stay focused longer.
Blue and green light from screens and bulbs tells your brain it's still daytime, holding back melatonin. Ryva night lenses filter that band so your body releases it on time and you fall asleep more easily.
Special cells in your retina set the time for your whole body. Bright light at night throws that clock off. Ryva helps you send the right signal at every moment of the day.
Cortisol should rise in the morning and fall in the evening. Artificial light at the wrong hours disrupts that cycle. Protecting your eyes at night helps your body shift into rest mode.
Your rhythm shifts through the day. So should your lenses.
Three tints built for three moments. Each color filters a different slice of light to carry your body from sunrise to night.
Focus without fatigue
Yellow tint, the gentlest filter. Cuts screen blue light without darkening your view, for your busiest hours.
ExploreAn easy transition
Orange tint, the middle filter. Widens the cut into green to follow the sun going down and the end of your day.
ExploreDeep rest
Red tint, the deepest filter. Blocks most of the blue-green, like candlelight, for the hours before bed.
ExploreThere's science behind every tint.
How light shapes your focus, your mood and your rest — and why lens color matters at every hour of the day.
