Smiths Pivlock Arena Optic Cycling/or Biking sunglasses with two extra lenses

I have a step father who is into cycling as he rides 26 miles daily. I bought these for him but like a dummy I should of asked first if he needed or would use. By the time his bday came around it was too late ti take back and I just hung onto them instead of getting in-store credit. They can be prescription if needed. The interchangeable lenses are green and the other is more a brownish color. And the ones together are blue but on glasses say tortoise. Comes with case. Feel free to ask any questions. Also, the green lense has some scratches (from me being stupid and trying to change the main glasses from blue to green) and my finger nails scratched it but it’s not in the middle or in viewing sight while wearing
