In a short daily halachic video segment on Kikar HaShabbat, Rabbi Benjamin Huta addresses whether it is permitted to go out on Shabbat wearing eyeglasses whose lenses darken in sunlight and turn clear again in the shade.
The item is presented as part of the site's "Halacha in 60 Seconds" feature, which Rabbi Huta delivers each morning and which aims to condense practical laws and customs into a brief, current format. The question discussed in this episode falls under the Shabbat prohibition of coloring, known in Hebrew as "tzovea."
The article notes that many people buy glasses with lenses that automatically change color depending on exposure to the sun, and asks whether that change could be considered a forbidden act on Shabbat. Viewers are directed to watch the accompanying video at the top of the article for the halachic answer.
No detailed ruling is quoted in the text itself, only the issue under review and the fact that the explanation is given in the video segment.
