Blepharospasm, swollen eyelids, pruritus, photokeratitis, and photodermatitis of feet and eyelids were observed in all UVB irradiated birds at the outset of day 3 of experiment BB1, at which point this experiment was stopped.

Photokeratitis and photodermatitis result from excess exposure.

However, a dose of 180 mJ/[cm.sup.2] (BB3), the product of a longer exposure to less than half the irradiance compared with BB1, resulted, in a few birds, in only mild signs of photodermatitis and photokeratitis after 4 days.

When considering this, we can infer that the minimum dose (MED) of broadband UVB capable of causing photokeratitis and photodermatitis in budgerigars ranges between 150 and 300 mJ/[cm.sup.2], which is 10 times the MED for humans.
