I am 67 and three years ago I was diagnosed with uv aggravated eczema. The doctors recommend wearing close woven fabrics to block uv but i find they don't really cut the mustard. my idea is to sew a lining into the back (where most irritation occurs) of a lightweight jacket and insert a sheet of aluminium foil to block the uv. What do you think? i would be extremely grateful for some feedback or do you have any more ideas?
