Abstract

La présente invention concerne un dispositif de visiocasque (1) comprenant : un corps principal de lunettes (10), une extrémité du corps principal de lunettes (10) étant pourvue d'une partie destinée à être portée (120) adaptée à un utilisateur, et l'autre extrémité du corps principal de lunettes (10) étant pourvue d'un espace de montage de lentille (210) ; une lentille (30), disposée dans l'espace de montage de lentille (210) ; une partie de montage de lentille (20), disposée sur le corps principal de lunettes (10) et à proximité de la lentille (30), la partie de montage de lentille (20) comprenant une surface de montage proche de la lentille (30) ; et un panneau d'absorption d'humidité (40), disposé sur la surface de montage de la partie de montage de lentille (20). Lorsque le dispositif de visiocasque (1) est porté sur la tête d'un utilisateur, le visage de l'utilisateur et la partie destinée à être portée (120) du dispositif de visiocasque (1) forment ensemble un espace relativement fermé. Lorsque les niveaux d'humidité augmentent en raison de la transpiration de l'utilisateur, l'humidité accrue dans l'air peut être absorbée par le panneau d'absorption d'humidité (40), ce qui empêche l'humidité d'adhérer à la surface de lentille (30).
