    Phantomaz,

    365/385 nm , , !!!!!!
    :
    Symptoms of UV exposure may not appear immediately; they can be delayed by 30 minutes to several hours. They can include a burning or "sand in the eyes" sensation, and a hazy look around light bulbs and other bright objects. Mild cases are self-correcting within 24 to 36 hours; however if despite my warnings you still stared at the LED from close range for more than a few minutes, it might not be a bad idea to see an eye doctor and tell him you've been exposed to UVA radiation.
