Gold Tint Eyeglasses and 19th Century Mirror Viewfinder for Painter

I found that there was a fashion at painting art , between painting artists and lots of people who interested at landscape paintings at 19th Century.
That was using a cobalt or gold tinted glass or black mirror to view the sunsets , foliage , sea or historical buildings with richer definition.


I found there are lots motorcycle , riders goggles sold at internet. I found there are two gold tinted glasses at sell , one is real gold colored glasses and second is faint pinkish brownish light shade glasses which sold as gold tint. I found second at lee filters and goes tan color with lower kelvin.

I want to improve my sight and I want to ask which one was closer to these painter glasses and your experience with them.

Is there a comparison pictures with above and normal lenses.

And is there exotic rare earth glasses somewhere ?

I have vision problems and find yellow tinted eyeglasses improve my vision particularly when reading. The eye is a simple lens and therefore cannot focus all portions of the visible spectrum at the same time. The yellow tint removes some of the blue light improving focus. My eye doctor recommended them.

I have bought above , wishing to improve colors.

Looking at the reflection of a gilded-mirror will be different than looking through a gilded glass. And the effects on looking through will evern depend on the thickness of that gilding.
