FC Porto’s Samu uses anti-blue light glasses to ease fatigue and stress | OneFootball

FC Porto’s Samu has been working on managing his emotions on the pitch, and off it he is using every tool available to sustain high performance. That includes medically prescribed anti-blue light glasses to reduce fatigue and stress from screens and other lights and to aid his sleep.

According to O Jogo, he surprised some observers in Plzen by wearing sunglasses during a night-time stroll on the pitch. The same look was seen again the day before yesterday as he arrived at the stadium for the match.

These are not tech-enabled frames for music or calls, nor simply a style choice. They use lenses that filter blue light, which inhibits the body’s production of melatonin. The doctor prescribed them to help the Spaniard cut strain from screens and improve his sleep cycle.

That will naturally have positive effects on day-to-day performance in training and in matches.

The immediate focus is on helping Samu recover emotionally after two errors, ensuring he is not affected by them and can offer the best possible response in the next game against Gil Vicente.
