The Nevada Junior children's ski goggles are OTG, which means they are compatible with prescription glasses. The double cylindrical lens ensures excellent vision to young riders and creates a thermal barrier between cold and hot air to prevent condensation. The inner lens has an anti-fogging coating to reduce moisture build-up. The frame has built-in FlowTech ventilation that also prevents fogging. The dual density foam in direct contact with the face is very comfortable.   Features of the Bollé Nevada Junior:  Small fit Cylindrical lens P80+ anti-fogging coating Double lens Carbo Glas anti-scratch coating FlowTech ventilation Dual-density foam Compatible with optical clips  Silicone strap OTG Cleaning cloth included Goggles Bollé ---Nevada Junior White Matte Rose Gold
