How does powerful laser light affect the eyes?

50mw Green Laser Pointer may be inexpensive to buy, but there's fun in making your own. A homemade laser pointer will work as well as one from a store and give you a sense of accomplishment every time you see the laser beam. The process of making a homemade laser is not complicated and just requires buying a laser module and an LED flashlight.

Twist the AixiZ laser pointer 300mw housing between your hands to separate the front and back casings from each other. Discard the front casing of the AixiZ laser housing. Heat up the soldering iron. Take the back section of the AixiZ laser housing that has the exposed laser diode now showing and place it down on the towel.

Solder a conductive pin each to the positive and to the negative contacts on the body of the laser diode. Let the solder cool.Insert the back half of the AixiZ laser housing, conductive pins first, into the LED flashlight. Apply a thin layer of bonding glue to hold the AixiZ 100mw green laser housing to the inside of the LED flashlight. Let the bonding glue dry.

Screw the reflector back onto the LED flashlight. Put the batteries back into the LED flashlight and screw on the battery cap.Aim the LED flashlight that has now been turned into a homemade laser pointer at a wall across the street. Press the button to project the Red laser pointer 5mW 3in1 light onto the wall.

How does laser light affect the eyes?

Several variables change how the eye is affected. Power level of the laser, duration of exposure, and the wavelength of the light all impact the negative affects of laser light on the eye. Green laser light is also far more damaging than red laser light, appearing 30 times brighter to the human eye. According to the FAA, most incidents involve handheld green laser pointers.

Boeing explains that visible laser light is magnified once it enters the optical system, targeting the retina of the eye. The mildest form of laser light causes glares that temporarily impair a pilot’s vision, and at long distances this is usually just an annoyance. However, when the light is stronger or the pilot is flying closer to the source, this annoyance escalates into the inability to see landmarks and even the instrument panel right in front of them. Strong light can also cause flash blindness, which causes the pilot to lose their vision for a brief period of time ranging from few seconds to a few minutes.

Afterimages often occur from very strong laser light exposure, resulting in colored dots appearing in front of a pilot’s eyes for a brief time. Serious retinal damage is a possibility if the pilot is exposed to very powerful laser lights in close proximity. This causes burned retinal tissue, resulting in permanent blind spots in a pilot’s vision.
