Video: Tác dụng của viền đen vẽ dưới mắt vận động viên


Các vận động viên bóng chày và bóng bầu dục thường kẻ những vệt đen dưới mắt để ngăn phản xạ ánh sáng gây chói mắt và giảm tầm nhìn, những vệt này được gọi là “mắt đen”.


Da tự nhiên chỉ hấp thụ được một phần ánh sáng, phần còn lại sẽ bị phản chiếu… gây ra hiện tượng chói mắt và làm giảm tầm nhìn. Những vệt đen này có tác dụng ngăn chặn da phản xạ ánh sáng bằng cách hấp thụ toàn bộ ánh sáng chiếu vào. Điều này giúp vận động viên tập trung hơn thi đấu.

Một trong những vận động viên đầu tiên sử dụng “mắt đen” là Babe Ruth.
