A man has allegedly glassed a 22-year-old in the face during a fight in the NSW Snowy Mountains.

The two men aged 22 and 30, were at a function on Kosciuszko Road, Jindabyne, when a fight broke out about 12.10am (AEST) on Saturday.

The older man allegedly hit the 22-year-old on the face while holding a glass, police said.

He suffered multiple cuts to his face and was taken to hospital for treatment.

The other man was treated at the scene for lacerations to his fingers.

He's been charged with grievous bodily harm by a negligent act and was bailed to appear at Cooma Local Court on October 9.
