When exposed to sunlight, the card changes color — a deeper, more vivid color indicates stronger UV intensity. Simply hold the card in the sunlight for a few seconds to get an instant visual reading of UV conditions.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Are these UV indicator cards reusable?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! These UV test cards are designed to be reusable. After removing them from direct UV light, the color gradually fades back, allowing you to use each card multiple times for repeated outdoor UV checks.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What UV wavelengths do these cards detect?\u003c\/h4\u003e\n\u003cp\u003eA: These cards respond to a UV wavelength range of 230–280 nm, covering a key portion of the UV spectrum relevant to outdoor sun exposure and skin protection assessment.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How can I use these cards to test UPF clothing or sunscreen?\u003c\/h4\u003e\n\u003cp\u003eA: Place the UV test card in direct sunlight to see the baseline UV color. Then place the card under your fabric or apply your sunscreen to the card's surface and compare — a lighter color indicates effective UV blocking, while a deeper color suggests more UV is getting through.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"How do UV test cards work?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"UV test cards use a photosensitive coating on quality art paper that reacts to ultraviolet light.
