Anti-Fog Glasses

I want to buy glasses that do not fog up.

Glasses fog up when wearing a mask! We can address the discomfort you feel in daily life.

Why do glasses fog up when we are required to wear masks in daily life?

Glasses fog up due to "fog formation." When the moisture contained in the exhaled air comes into contact with the lenses and cools down, it forms fog. The lenses lose their clarity due to light being diffusely reflected, making them appear foggy. In particular, lenses are more prone to fogging in winter when temperatures change significantly and in air-conditioned rooms or trains during the humid rainy season.

Solutions / Improvements

• Use anti-fog lenses (anti-fog lenses).
• Use anti-fog spray or specialized lens wipes.
• You can reduce fogging to some extent by taking measures to prevent exhaled air from leaking from the mask onto the lenses. *Note that the effectiveness of anti-fog products depends on the environment of use.
