Preserving your night vision means that when we go observing the stars, we go to dark locations and let our eyes adjust to the dark so we can see more detail in the astronomical objects we observe.
If the light is too bright then our eyes loose the dark adaptation and our pupils close down more so we try and preserve our dark night vision by using dimmer lasers.

Yes, when burning you have to wear safety goggles and they do make everything look coloured, like the filter but the beam dot will be a different colour since the filters stop the harmful wavelengths.

Have a look through my threads, I am currently building an RGB and White laser, see link below.
{Link} Genesis Project: my RGB White Rainbow - Proof of Concept build.

Also search my threads as I've posted many astronomical photos.

Thank you, you should visit Australia, it's a very nice country to visit and people are very friendly.

Regards
RB

Hi Andrew,

Thanks a lot for your explanation.

I found your Yellow 589nm thread. The bright yellow beam is amazing and unique.

Your RGB White laser project is fascinating, and also this wonderful picture of the deep space that you've taken, mind blowing!

It'd be my honor to visit Australia and to meet your kind and warmhearted people.

Cheers.

Thanks, Paul.
BTW your avatar is very nice. I love oscilloscopes and their geeky mad scientist looks!

I'm so glad you liked my posts.

It would be our honour to have you visit Australia.
I also had a very good friend from Iran when I was at college studying Electronics, around 30 years ago.
He was a good friend and he had just migrated to Australia and we all made friends with him and showed him around.

Regards
Andrew

For God so loved the world that He gave His only begotten Son, that whoever believes in Him
should not perish but have everlasting life.
For God did not send His Son into the world to condemn the world,

but that the world through Him might be saved.
“He who believes in Him is not condemned;
but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.
And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil.
For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed.
But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.”
(John 3:16-21)
─────────────────────────────────☀
If you confess with your mouth, “Jesus is Lord,” and believe in your heart that God raised Him from
the dead, you will be saved.
For it is with your heart that you believe unto righteousness
and it is with your mouth that you confess
your faith and
are saved.
(Romans 10:9-10)

very much for your kindness, Andrew.
Really happy to hear that. I wish the world to be filled with good friendships and pure humanity. Reminded me of this famous poem
