Here's my story...
I bought a 10mw leadlight laser about a year ago i modified it changing the resistors, maxed out the pot, realized it was a little too bright so i knocked the pot back to half way, it visually now gives around 50 - 60mw and i'm very happy at the power....
however even with it fluctuating slightly if left too long on or when it over heats it produces a dual beam (mode switching?) if used for short periods it's fine problem free but...
Twice now i've hit a window / mirror and had the beam hit my eye full on, it was not a point blank but, but for 20 minutes or so all i could see was a green line of dots, blinking my eyes and seeing green blobs over everything... after about an hour or so, the dots went away BUT....
Now i'm not sure if the laser did this or not, but the brightness or intensity level of objects at night or low light don't show in the center, best way to describe this is in a dark room with a little light, you see objects, imagine a white towel, if i look straight at the towel i barely see it, but if i look slightly to the side of it in any direction, i see the white towel...
I'm short sighted have been since the age of about 12, too much using the computer, but this recent problem due to the laser ? anyone else have a similar issue? My brother-in-law sees "black dots" everywhere he looks in bright light due to doing some welding and i assume that's similar to what these people on here talk about, but can the intensity damage the way light is processed?
