Reticare

Reticare develops and sells optical filtering products intended to reduce the blue light (380–500 nm) and high-energy green light (500–590 nm) emitted by LED screens on phones, tablets and computers. The product line comprises adhesive screen protectors, priced from €17.90, and a range of RetiNaut eyewear: non-prescription glasses (€229), fixed-dioptre reading glasses for close-up screen work (€269) and full prescription replacement lenses with the RetiNaut filter integrated (€469). Each eyewear model is offered in two filter intensities — Clear, described as maximising transparency for daily use, and Intensive, aimed at long sessions or higher light sensitivity. The company states its filters reduce the targeted spectral bands without darkening the image or altering colour perception.

The technology is presented as the outcome of more than 20 years of scientific research at the Universidad Complutense de Madrid (UCM), carried out under the scientific 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. The company cites UCM studies describing increases in retinal cell death of up to 23% under high-energy light exposure models, and states that the filter technology is covered by an international patent. Eyewear is described as manufactured in Spain and weighing approximately 28 grams. Reticare also publishes a blog on screen light and visual health, with posts authored by Mª Isabel Gil Adsuar and Nilo Garcia.
