I looked for glasses similar to the ones George Tokoro wears on TV and in magazines! Photochromic Lens Glasses [Yellow (base color) ⇒ Color Change (Dark Gray)] Indoors, the lens is yellow (base color) ⇒ it changes color to dark gray when exposed to ultraviolet light. Frame color: Black Color Change Effect: High color density, and extremely fast color change speed! When not activated by UV light [indoors, cloudy days, night, etc.], the lens color is a light yellow, which allows for clear visibility! Please note: As mentioned above, this product uses photochromic lenses that change color due to ultraviolet light, not photochromic lenses that change color due to visible light. Please understand. From comments actually made by eyewear retailers: The degree of color change varies depending on the weather, climate, and season (hot or cold). The attached photos are of the actual product, but the degree of color change may vary depending on the situation. Please be aware of this. We want to offer a reasonable price as much as possible, so we are assuming shipment of the glasses alone, but we will of course provide a glasses case (including lens cloth) to those who want one. [Specific items will be announced separately.] However, due to the additional shipping costs (including packaging), we would like to offer it for an additional 300 yen. Thank you for your understanding. *We try to respond as quickly as possible, but we may take some time to respond during the day because I am working.
