OWNDAYS has released heat-resistant, crack-resistant sauna glasses that can be worn in the sauna. The price is 8,800 yen (including lens fee).
Uses completely custom-made lenses that can accommodate left-right differences and astigmatism. The Wellington-type design is suitable for everyday use, and uses heat-resistant, shape-change-resistant materials and heat-resistant lenses that do not fog up easily.
No screws or other metal parts are used, eliminating the risk of rust, and the compact, dedicated pouch makes it easy to carry around.
It is available in four colors: Totoi Meditation Black, Water Bath Blue, Heat Wave Red, and Vichita Green.
