Can Laser Injury Increase The blind spot?
Can a grade 3 A laser that hit the eye do permanent damage to the field of view?Whatever that means.
A symptom-producing, or pathiological, scotomata may be due to a wide range of disease processes, affecting any part of the visual system, including the retina. See: https://en.wikipedia.org/wiki/Scotoma
Can a laser damage the retina --yes. See: https://laserpointerforums.com/threads/hit-in-eye-with-1000mw-445nm-blue-laser.69469/
Ask a qualified MD ophthalmologist about any particular real world instance.

You mean class 3a right? In that case no, you will be fine. Just dont be stupit with it and you will be fine.Can a grade 3 A laser that hit the eye do permanent damage to the field of view?
I think I had a left eye injury.RedCowboy and I gave you a real answer -- just ignore the meaningless response above which says you will be fine unless you are not fine which means nothing.
Beyond that you can read about Class 3R/IIIa laser hazard here: https://www.lasersafetyfacts.com/3R/
Says among other things:
"EYE INJURY HAZARD -- DIRECT AND REFLECTED BEAM
Class 3R visible-light lasers are considered safe for unintentional eye exposure,
because a person will normally turn away or blink to avoid the bright light. Do NOT deliberately look into or stare into the beam -- this can cause injury to the retina in the back of the eye.
Be aware of beam reflections off glass and shiny surfaces. Depending on the surface, the reflected beam could be about as strong and as focused as a direct beam.
If you are closer than the NOHD distance to the laser, there is a possibility of retinal damage if the direct or reflected beam enters your eye longer than about ¼ second. The closer you are to the laser and the longer the beam is in the eye, the greater the chance of injury
Blind spot should not be a very small and not large spot? Like I described?Your eye has a natural blind spot that everyone has. It is the place where the optic nerve enters the retina. Normally you don't notice it because your brain compensates for it, but it can be seen if you open just one eye and use a moving object to observe this while staring at some point in space. If you are concerned about retinal damage you should see an ophthalmologist. This is the only way to be certain.

At first I thought it could be fear of not wanting to go to a doctor to hear the truth like some people do.
But going back to the OP's thread this is the one who constantly posted about his fear of his work laser bar scanner??
