The present invention discloses a goggle and a frame thereof, the frame including a fastening structure at an end thereof, and the fastening structure forms an accommodation space and an entrance and exit which communicates with the accommodation space. The fastening structure includes a cantilever located in the accommodating space and a blocking wall disposed in the accommodating space and spaced apart from the cantilever. A free end of the cantilever is positioned adjacent to the access opening, and the cantilever is swingable between a latched position and an open position. The free end shields the entrance and exit when the cantilever is in the latching position； and the free end does not obscure the entrance and exit when the cantilever receives an external force and swings to the open position, And the cantilever has a restoring force.本創作公開一種護目鏡及其框架，所述框架包含有位於其末端的一扣持結構，並且所述扣持結構形成有一容置空間及連通於所述容置空間的一出入口。所述扣持結構包含位於所述容置空間內的一懸臂及位於所述容置空間內並與所述懸臂呈間隔設置的一擋止壁。所述懸臂的一自由端部的位置鄰近於所述出入口，並且所述懸臂能於一扣持位置與一開啟位置之間擺動。當所述懸臂位於所述扣持位置時，所述自由端部遮蔽所述出入口；而當所述懸臂接受一外力而擺動至所述開啟位置時，所述自由端部未遮蔽所述出入口，並且所述懸臂蓄有一回復力。
