Stevens–Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN)[1] are two forms of a life-threatening skin condition, in which cell death causes the epidermis to separate from the dermis. The syndrome is thought to be a hypersensitivity complex that affects the skin and the mucous membranes. Although the majority of cases are idiopathic (without a known cause), the main class of known causes is medication, followed by infections and, rarely, cancers.
Ugh!
That’s correct about SJS. Thank goodness I had a caring, long time doctor who diagnosed it quickly and we caught it early. Wear a med bracelet now that lists Keflex, Penicillin, Sulfa and a couple others that are dangerous for me. So far, Cipro is ok if necessary.
It’s relatively rare and some family physicians never see it in their practices, so thank the Lord for my doctor.
From Wikipedia: "Ordinary glass is partially transparent to UVA but is opaque to shorter wavelengths, whereas Silica or quartz glass, depending on quality, can be transparent even to vacuum UV wavelengths. Ordinary window glass passes about 90% of the light above 350 nm, but blocks over 90% of the light below 300 nm.[6][7][8]
UVB is 280nm to 315 nm."
Even the cat on the windowsill will not get enough beneficial sunlight through glass.
