SUMMARY

The discussion centers on the phenomenon of chromatic aberration experienced by individuals wearing glasses, which causes the edges of objects, such as paper or other items, to appear with colored halos (yellow/red or red/green/violet) at certain angles. Users noted that this effect is more pronounced with specific lenses and can be mitigated by removing the glasses. The conversation highlights the similarities between this visual distortion and the chromatic aberration observed in optical devices like refractor telescopes and binoculars.

PREREQUISITES
  • Understanding of chromatic aberration in optics
  • Basic knowledge of lens types and their properties
  • Familiarity with optical phenomena related to light and vision
  • Awareness of how glasses can affect visual perception
NEXT STEPS
  • Research "chromatic aberration in eyeglasses" for detailed explanations and examples
  • Explore "optical lens design" to understand how different lenses minimize aberrations
  • Investigate "refractor vs. reflector telescopes" to learn about their optical differences
  • Learn about "visual artifacts in eyewear" to identify other potential issues with glasses
USEFUL FOR

This discussion is beneficial for individuals studying optics, eyewear professionals, and anyone interested in understanding visual perception and optical phenomena related to glasses.

Hello,

I study physics on my own, but jump from one area to another and am also a beginner, so if this question is easy and obvious then my apologies. However if it is complicated, please answer it with whatever terms neccessary.

I have noticed that while in class (not physics) if I am looking down at my book on my desk that the edges of the paper will not appear white (which is the color of the paper) at certain angles. I end up seeing yellow/red lines/glow of the paper. It actually looks that color. I wear glasses and if I look at it from a certain way then I am thinking that the light from the ceiling is bouncing from my lens to my eye causing me to see the paper differently. Would this make sense or am I going about this wrong?

Also, the same thing happens wth another object in my room. If I am at a certain angle towards my lamp then an object I look at has a very defined red/green/violet hugh around it.

What is going on?

Thanks a lot

Hi and welcome to this forum!
Maybe it's a chromatic aberration of your lenses making up your glasses. See http://en.wikipedia.org/wiki/Chromatic_aberration.

P.S.:It happens with my glasses too but I can only see blue and red for contour of objects. This didn't happen with my previous glasses. If I remove my glasses the aberration disappear so my eyes have a smaller chromatic aberration than my glasses.
 
This same effect happens in refractor telescopes and binoculars. That is one of the main reasons that many people use reflecting telescopes, as they do not suffer from this effect.
 
Chromatic aberration is probably it, thanks.
 
Because eyeglasses are reflective surface as well, and not just refractive surfaces, there are other annoying visual artifacts as well. For instance, under proper lighting and at the right angle, you can see an image of your own eye in your glasses.
