The light is collected by our eyes and focused on the retina, where it is converted into nerve impulses and sent to the brain, where it is formed into images. Also, note that a or call is required as the last element of text sent to window you are opening. The locnm code lets us get the local or server file path to the file or image desired. Even sparklers are hazardous to the eyes because they are held in the hand and often swung into the air, near the eyes. Other Class C fireworks, which include small firecrackers less than 1.5 inches long, roman candles, fountains and bottle rockets, also pose hazards to the eyes.
Adults often think sparklers are safe even for young children.
Yet sparklers burn at temperatures up to 1,800 degrees and a hot spark from one can seriously burn an eye or eyelid. Sometimes permanent damage to the eye or vision may result. Sparks from other Class C fireworks can cause similar damage to the eyes. Bottle rockets pose additional hazards. Their flight path is often erratic and rocket launchers sometimes explode, sending pieces of glass or metal flying.
