There is usually no difference between cycling glasses for women and men in terms of quality or performance. The main difference is often in the fit, as men and women often have different face shapes and sizes. Some brands offer specific lines of cycling glasses for women and men that are tailored to the average face shapes and sizes of each gender.
There may also be colour and style differences between cycling glasses for women and men. This is usually more a matter of personal preference and does not necessarily mean that one type of cycling glasses is better or worse than the other. When looking for cycling glasses, it is important to look at the specific features of the glasses, such as fit, lens quality and UV protection, rather than focusing on the gender the glasses are intended for.
