Overview

• Inside the national-team camp, Marcos Llorente details his light-management approach, using yellow lenses indoors during the day, red lenses after sunset, and avoiding sunglasses outdoors.
• He says he keeps artificial lights off during daylight and relies on red or infrared lamps at night to emulate outdoor conditions.
• The Atlético de Madrid player describes a paleo-style diet with intermittent fasting, cutting ultraprocessed foods, cereals and most dairy, and eating two meals while the sun is up.
• Aymeric Laporte arrived at Las Rozas wearing yellow-tinted glasses after being called up to the squad to cover for Huijsen’s injury.
• Optometrist Imanol Carretero argues the yellow lenses are a marketing tactic without evidence for preventing eye strain or retinal issues, noting only that blue light can affect sleep; Llorente has also faced online criticism over remarks about contrails and the sun’s role in disease, which he has rejected.
