Because of the aggregation effectof the eye lens, the laser energy (power) is more than 100 thousand timeshigher than that of the corresponding cornea. Laser monochromatic good, smallcolor difference in the fundus. Because pulse laser injury is much faster thanthe blink reflex (eye blink reflex time is usually 150-250ms, and the laserpulse can be as short as 10-6s and 10-12 S). Plus in a very short moment, in avery small area, gathering energy release, so even if the laser low dose cancause severe damage on the cornea or retina. And the damage to the human eyelaser is a heap of, the beginning is not significant, when it is too late tofind yourself.
The use of laserand special features in our life has incomparable importance, but also becausewe cannot practice on laser do not know do not know and trust blindly laser,laser brings us the day day is very quick to strong, but the same laser damageand loss to us more serious, we should clearly recognize the clear dangers andlimitations of laser.
