These are Zoff PC glasses with blue light cut lenses. Non-prescription. I bought them because my eyes get tired when gaming, and I wore them about twice, but I haven't been gaming much lately, so I'm selling them. Disinfected at home. Please refrain from purchasing if you are concerned as they have been worn. - Brand: Zoff - Model: PC GLASSES - Type: ULTRA TYPE - Lenses: Blue light cut - Frame color: Black - Retail price: ¥5,500 (tax included)
