Sunglasses with adjustable width between legs

The invention relates to a pair of sunglasses, specifically to a pair of sunglasses with adjustable width between legs. The invention aims to overcome the problem that unadjustable distance between two legs of the sunglasses influences wearing comfortableness. The sunglasses comprise a frame and two legs; the head end of each leg is connected with the outer side edge of the frame via an adjustment connection assembly; each adjustment connection assembly comprises an adjusting screw, a frame clamping mechanism and two guide pillars; the head end of each leg is provided with a counter bore; and two through holes are symmetrically formed in two sides of each counter bore. The sunglasses with adjustable width between legs are used for blocking solar rays.
