Gafas con filtro rojo - Red Filter Glasses

Promote your nightly rest
By filtering up to 99.92% of HEV blue light in the hours leading up to sleep, they help your body not inhibit melatonin production and prepare for sleep naturally.

Support your circadian rhythm
They reduce the artificial light signal that confuses your internal clock, so your body continues to interpret day and night as it should, even if you end the day in front of a screen.

Greater visual comfort in low light
The red lens softens glare from mobile phones, computers, and televisions in dimly lit environments, alleviating the feeling of tired eyes at the end of the day.

Filtration that doesn't wear out
The red pigment is physically infused into the lens; it is not a surface coating. The filtration remains constant and homogeneous use after use, without degrading with cleaning.

Lightness you forget about
At only 34 grams and with a hand-polished, hypoallergenic Mazzucchelli acetate frame, they can be worn for hours without discomfort or marks.

A simple gesture to take care of yourself
No apps, no complicated routines, no giving up your screens. You put them on 1 to 3 hours before bed and let them do their job.

How they work, scientifically speaking

The key lies in the retina. In addition to the rods and cones we use for vision, the eye has a third type of photoreceptor: intrinsically photosensitive retinal ganglion cells (ipRGCs), which contain a photopigment called melanopsin. Their peak sensitivity is around 480 nm, right in the blue band of the visible spectrum.

When these cells detect blue light, they send a direct signal to the suprachiasmatic nucleus, the brain's central circadian clock, which in turn regulates the secretion of melatoninin the pineal gland. During the day, this is a useful mechanism: blue light keeps us alert. At night, the light from screens activates this same pathway, the brain interprets that it is still daytime, and inhibits melatonin production, delaying sleep.

Red Filter Glasses intervene at the source of the problem: the light reaching the eye:

• Verified 99.92% HEV filtrationin the 380 to 500 nm range, with independent laboratory reports available upon request.
• Physical red pigment infusion:the pigment is integrated into the lens material, it is not a surface coating. This ensures homogeneous filtration across the entire surface and prevents degradation from cleaning or use.
• Resulting spectrum close to sunset:by blocking the wavelengths that activate melanopsin, the light that passes through the lens resembles that of dusk, consistent with the signal the body expects at that time.

The optical substrate is CR39 (Columbia Resin #39, poly(diethylene glycol bis(allyl carbonate))), an organic resin with a refractive index of approximately 1.50 and an Abbe number close to 58, which translates to sharp optics and low chromatic aberration. It is also lighter and more impact-resistant than mineral glass, and meets the optical safety standards of the European and American markets.

All in all: 34 grams of optical engineeringat the service of one thing: ensuring your circadian rhythm doesn't depend on when you turn off your screen.

• You work or relax in front of screens until late at night.
• You find it difficult to disconnect at night and want to protect your sleep without giving up your devices.
• You notice eye strain or screen glare in low-light environments.
• You want to support your circadian rhythm simply, without apps or complicated routines.
• You are looking for a carefully crafted, light, and durable piece that combines science and premium design.
• You understand well-being as something that also begins with good rest.
