The skin is usually much less sensitive to laser light than the eye, but excessive exposure to ultraviolet light from any source (laser or non-laser) can cause short- and long-term effects similar to sunburn, while visible and infrared wavelengths are mainly harmful due to thermal damage.
BOOSTER SEAT LAW. Children over forty pounds or who have reached the upper weight limit for their forward-facing car seat must use boosters to 4'9 tall or age eight and the adult belt fits correctly.
A booster seat is used to lift up a child and properly position the vehicle's lap/shoulder belts on children who are too small to fit the adult seat belt. Boosters are rated for use from 30-40 lbs to 80-100 lbs. Booster seats do not have a harness. FITS YOUR CHILD. Many booster seats have a minimum weight of 30-33 lbs. However, a booster seat should not be the next purchase when the child outgrows a convertible seat. A child is safest if they remain in a harnessed seat until they reach at least 40 lbs.
