Traditional laser pointer group buying has two disadvantages: First, they cannot be in the LCD display. And: the lecturer must turn away from the audience.

The 1000mw laser pointer is becoming more and more popular among students, but some students walk the laser pointer back and forth with their eyes. Experts suggest that when the eyes are in direct contact with the laser pointer, it is easy to damage the eyes and even cause permanent blindness. Since the laser is a femtosecond laser type, the execution can achieve more precise and better final results. The complications of cataract surgery are usually related to lens calculation errors, complications during and after surgery, but with the advent of femtoseconds, this concern is greatly reduced. Another advantage is that the use of laser makes the positioning of the intraocular lens implant more reproducible, so the operation is safer to correct small details that cannot be reached by human hands.
Experts said that the high power laser pointer under the light is very bright, which is very attractive to children. There are many children's purchasing power, especially the bright and powerful laser pointer. However, this kind of laser pointer is more harmful to the eyes. When the laser pointer beam directly irradiates the eyes, it is easy to cause permanent blindness. The laser light emitted by the blue laser pointer has the characteristics of focusability, strong directivity and focused beam. When the child stares at the laser pointer, the laser is directed at the center of its macula. Because the laser can generate heat, the longer it generates, the greater the heat that will eventually produce severe radiation burns, and the photoreceptor cells will die.
