The aim of this paper is to test the influence of the laser brightness on the retina of eye of lacerta laevis, and the value of the distortion or damage in the construction of photoreceptors (Cones), which are responsible of the viewing process or in the pigmentary epithelial layer which protect from the high light intensity. On the other hand, the continuation of the exposure to the He- Ne laser beam the number of the damaged cells, that causes the loss of entire photoreceptor layer. The results show similar effects at specular reflection. Hence, it is very important to pay attention to the hazard emerged from the laser beam in visible range, which requires to apply the special goggles, as well as to keep the laser pointers out of reach of children.
