JC Sunset - Ra Optics
Introducing the JC Sunset glasses by Ra Optics, an innovative and stylish solution to protect your eyes from harmful blue light exposure at night. These glasses have been meticulously designed to provide maximum comfort while offering unparalleled protection against blue light, ensuring your eyes remain healthy and your sleep uninterrupted.
These red lenses are the ideal choice for use during the period after sunset and before bedtime, when you are most exposed to sources of blue light (LED lamps, screens, TV, etc.). Red lenses are not necessary when blue light is not present, such as with candles, campfires, and red or orange lights.

BENEFITS OF Sunset™ LENSES
- Help synchronize the circadian rhythm, promoting the resetting of your biological clock.
- Support the natural production of melatonin, the hormone responsible for preparing the body for sleep.
- Help you fall asleep faster, promoting a more natural transition to rest.
- Promote deeper and more restorative sleep, favoring REM sleep phases.
- Support the natural cellular regeneration processes that occur during the night.
- Contribute to waking up feeling more rested and revitalized.
- Suppresses melatonin production by up to 90%;
- Keeps cortisol elevated when it should be decreasing;
- Disrupts cellular repair processes;
- Promotes dependency on sleep aids;
- Accelerates aging and increases the risk of disease.
The light that promotes rest
The RA Optics Sunset lenses block 100% of the wavelengths that interfere with melatonin production, allowing the body to:
- Relax naturally, without alcohol or sleep aids;
- Produce melatonin in the way nature intended;
- Activate the cellular repair and regeneration mode;
- Sleep more deeply, with a higher proportion of REM sleep;
- Wake up refreshed and with better hormonal balance;
- Support healthier aging through proper nighttime recovery.
THE SCIENCE OF Sunset™ LENSES
During the night, the light emitted by screens, LED lighting, and other electronic devices can keep the brain in "daytime mode," making natural relaxation and preparation for sleep difficult.
The Sunset™ lenses filter wavelengths between 380 and 540 nm, precisely the range of the light spectrum most associated with daytime light signals. By using them after sunset, you reduce exposure to this light, helping the body to enter its nocturnal biological rhythm more naturally.
The result is a sense of greater visual tranquility, allowing the mind to slow down and the body to prepare for a more natural rest.
Sunset™ lenses were developed to provide precise and comfortable filtering, making it simple to integrate better light hygiene into your daily routine.
