Why we exist
Science applied to protecting your eyes.
- 01Preventive protection, not aesthetics.
Every product is designed with biomedical criteria validated in vivo and in vitro. Form follows function, never the other way round.
- 02Science before marketing.
Everything comes from Dr. Celia Sánchez-Ramos’s research at the Complutense University of Madrid. More than 20 years of evidence, not trends.
- 03For everyone, from day one.
From children to anyone who spends the whole day in front of a screen. More than 600,000 people in more than 40 countries.
Two ways to protect your eyes.
In front of your eyes, whatever screen you are using. Or on the screen itself, for everyone who looks at it.

How the filter works
The science
Twenty years of science before the first frame.
Since 2002, Dr. Celia Sánchez-Ramos and her team at the Complutense University of Madrid have studied how light affects the retina. These are the experiments, one by one.
“We have created the best glasses there are to protect against screen light.”
Dra. Celia Sánchez-RamosWorld leader in research on the effects of light on the eyes
- 2002–2003
First experimental studies on the retina
Animal model: rats · one yearProlonged exposure to white light, blue light and white light without blue, with and without selective filters.
Finding: significant retinal damage in eyes exposed without protection to radiation around 450 nm.
- 2003–2005
How cells respond
Animal model: rabbits · two years12 h / 12 h light and dark cycles with white and blue light, and intraocular lenses with and without a filter in each eye.
Finding: unprotected retinas activate cell death mechanisms; photoprotected ones activate survival mechanisms.
- 2006–2015
Clinical studies in people
Clinical study · seven yearsDaily exposure to ambient and screen light, with intraocular lenses with and without a protective filter.
Finding: without a filter, thinner macula and more eye alterations; with a filter, the structure of the retina remains stable.
- In vitro
LED light on human retinal cells
Human donor retinal cells · one yearBlue, green, red and white LEDs in 12 h / 12 h cycles, with and without photoprotection.
Finding: cell survival rose from under 10% to over 80% with selective photoprotection.
- 2015–2016
Validation in real use
Animal model: ratsProlonged exposure to commercial tablet screens, with and without Reticare protection.
Finding: without protection, around 23% of retinal cells were irreversibly lost. With Reticare technology, damage was practically non-existent.

Why your screen light matters.
Illustrative chart.
- 1 / 2
The light from an LED screen
We spend more than 6 hours a day in front of screens. Their light has a sharp peak in blue and a broad band in green.
- 2 / 2
Blue and green, the high-energy bands
These are the two bands the Complutense University has been researching for more than twenty years.
What people notice when they wear them.
Naut filter the high-energy blue (380 to 500 nm) and green (500 to 590 nm) light from your screens. This is what people tell us most.
“Honestly, for me they are peace for my eyes, and I’ve only been wearing them for 2 days.”
Lautaro PortelaCreator of «La Verdad es Católica» on YouTube- Fewer headaches at the end of the day.
Many people who wear Naut every day notice more comfort when the workday ends.
- Less tired, less dry eyes.
After hours of computer, phone or tablet, your eyes reach the evening more rested.
- More comfortable in bright light.
People who are sensitive to light notice improvements in their daily life with regular use.
* Results may vary. Naut are an optical filter, not a medical treatment. Consult your specialist if you have persistent symptoms.

You won't notice it when you wear them. You'll notice it when you take them off and look at your screen with all the light.

I can say with certainty that if it weren't for these glasses I would not be making YouTube videos right now.

That fatigue is gone now. My eyes feel like they do when I wake up in the morning.
Eric ValladaresDigital entrepreneur · 60 days of use
My ophthalmologist told me: After many years I can see your cornea... you look great, your eye pressure is perfect.
El ChituTech content creator · 4 months of use
It is instant: I look at the screen with the glasses and the pain is much less. You don't realize how good they are until you compare.

What science has been warning for years
Blue light glasses: what they do and when they are worth it
Blue light glasses reduce the high-energy light from screens that reaches your eyes. Not all of them do the same thing: most only act on part of the blue light. The ones worth buying selectively filter blue light (380-500 nm) and green light (500-590 nm) and have research behind them.
Computer glasses: how to choose the right ones
Good computer glasses selectively filter the blue (380-500 nm) and green (500-590 nm) light from your screen, don't change colours, are lightweight and include your prescription if you need one. For eight-hour days, choose an almost transparent lens such as Naut Clear.
Prescription blue light glasses: options and prices
If you wear glasses, the most comfortable option is a single frame with your prescription and filtering of blue (380-500 nm) and green (500-590 nm) light. Reticare offers prescription Naut (€469, made to your exact prescription) and Naut reading glasses with fixed diopters (€269) for close-up vision.
Frequently asked questions
Everything you need to know
We answer the most common questions about our products, the science behind them and how the purchase process works.
Reticare's scientific backing
Reticare is not a cosmetic product — it is optical technology developed with more than 20 years of scientific research from the Universidad Complutense de Madrid (UCM). Our filters have been developed under the supervision of Dr. Celia Sánchez-Ramos, whose research group studies the effects of high-energy light on in vitro and in vivo retinal cell models.
Why use an optical filter for screens?
LED screens emit blue light (380–500 nm) and high-energy green light (500–590 nm). UCM research studies the effects of that cumulative exposure on retinal photoreceptor cells, a tissue that does not regenerate. Reticare optically reduces that spectral band before it reaches the eye. It does not replace periodic eye examinations.
Can I use Reticare glasses if I need a prescription?
Yes, we have a specific solution for our Naut model. You can purchase the Naut Prescription option directly on the website. Once your purchase is complete, our team will contact you to request your ophthalmological prescription and ensure there are no errors. After verifying the data, we will manufacture your custom lenses with your exact prescription and Reticare's optical filter integrated. Responsibility for the prescription lies with your optician-optometrist.
Do you ship internationally?
Yes, we ship worldwide. From our website you can manage orders to most countries. If you have questions about a specific destination or customs costs, contact us before purchasing.
When will my order arrive?
The average delivery time for in-stock products to mainland Spain is usually between 24 and 72 hours (business days). For the Balearic Islands, Canary Islands and the rest of Europe, delivery times are between 4 and 5 business days.
