We recommend wearing them whilst sitting still at first, then gradually transitioning to walking and outdoor use. Kafa uses an internal progressive design, resulting in a smoother transition zone that is easier to adapt to than traditional progressive lenses.\u003c\/p\u003e\n\u003cp\u003eQ2: Does the photochromic effect work inside a car?\u003cbr\u003eA: Car windscreens block some UV rays, so the lenses will darken less but not become completely transparent inside a vehicle. This is a normal optical phenomenon.\u003c\/p\u003e\n\u003cp\u003eQ3: Does blue light protection affect the colours you see?\u003cbr\u003eA: Kafa uses segmented blocking technology, which does not affect normal visual colour perception and does not cause significant yellowing.\u003c\/p\u003e\n\u003cp\u003eQ4: Is the folding mechanism prone to breaking?\u003cbr\u003eA: Featuring metal hinges and a reinforced structure, it is not prone to damage under normal use, and the folding case provides additional protection.\u003c\/p\u003e","brand":"dinoinbox","offers":[{"title":"45–49 years +1.00 (100 dioptres)","offer_id":48249518293146,"sku":"MH02777","price":14.99,"currency_code":"USD","in_stock":true},{"title":"50–54 years +1.50 (150 dioptres)","offer_id":48249518325914,"sku":"MH02777-1","price":14.99,"currency_code":"USD","in_stock":true},{"title":"55–59 years +2.00 (200 dioptres)","offer_id":48249518358682,"sku":"MH02777-2","price":14.99,"currency_code":"USD","in_stock":true},{"title":"60–64 years +2.50 (250 dioptres)","offer_id":48249518391450,"sku":"MH02777-3","price":14.99,"currency_code":"USD","in_stock":true},{"title":"65–69 years +3.00 (300 dioptres)","offer_id":48249518424218,"sku":"MH02777-4","price":14.99,"currency_code":"USD","in_stock":true},{"title":"70–75 years +3.50 (350 dioptres)","offer_id":48249518456986,"sku":"MH02777-5","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/8748\/7130\/files\/ScreenShot_2026-06-12_143721_386.jpg?v=1781247176","url":"https:\/\/www.dinoinbox.com\/products\/gold-framed-foldable-smart-zoom-anti-blue-light-photochromic-reading-glasses-progressive-multifocal","provider":"dinoinbox","version":"1.0","type":"link"}
