Why do we see a spectrum after Swimming?

Hey guys,
I recently noticed that, after a swim, when you look at the light, you see a spectrum around it. The light was white light. And you see it with naked eyes.
Can you guys explain this phenomenon?
The water did contain Chlorine and maybe other necessary chemicals required in swimming pool.
Thank you.

I am not a biologist or a medic but I do know that after I swam my eyes watered more.

The excess water on the surface of my eye is affected by surface tension and gravity so it must be pulled into a non spherical curve which hence is a prism and will refract light of different wavelengths at different angle so producing a spectrum.

Do what all good physicists do and I am going to do next time I swim - do an experiment.

If I hold my head as close as possible to vertically downwards and look at a light source directly beneath I would expect the spectrum to disappear


Regards

Sam

You're right. I need to experiment it different ways. But it must happen when we cry. Oh, I am not certain but your answer is somewhat correctly related to sphere formed by tear drop. And I think yes we see a spectrum when we cry.
Holy, I can't even cry right now.
Thanks for the answer.

My guess that the cornea is absorbing some of the chlorine or other chemicals from the water, (chemicals tend to transfer from higher concentrated fluids to lower concentrated fluids), resulting in a slight fogging of the cornea. Once you're out of the pool, eventually the chlorine or other chemicals will get dispersed by the fluids produced at your eyes.

I can explain the phenomenon you observed after swimming. The spectrum you see is called a rainbow, which is created when white light is refracted, or bent, as it passes through water droplets in the air. This refraction separates the white light into its component colors, creating the spectrum you see. The presence of chlorine and other chemicals in the water may also contribute to the formation of the rainbow by altering the way the light is refracted. Additionally, the movement of the water and the way it interacts with the light may also play a role in the appearance of the rainbow. I hope this explanation helps to satisfy your curiosity about this fascinating phenomenon.
