Dr. Kepler believes that it is either a precurser of cataract or dry eye. He recommmended Systane eye drops. At night the eyes open wider and allow more light in that could refract into rainbows more clearly since more of the eye surface & wet tear layer as well as lens distortion would come into play.

He says that glaucoma will not present rainbow symtoms.

so I guess I'm starting to dry out ;)

Cataracts. resulting from the gradual yellowing of the normally clear lens of the eye, can cause floaters but I dunno about rainbows. It is typically addressed by replacing the lens with an artificial one that is clear.

IN glaucoma, the normal fluid pressure inside the eyes slowly rises, leading to vision loss or even blindness.

Neither one is anything to fool about with.

You live in a country where effective treatment with other drugs is possible. Go see an opthalmologist immediately and quit bitching.

It's detectable with an instrument that puffs a little jet of air onto your eyeball, it makes you jump, but it doesn't hurt, get it done.

Glaucoma yikes. Unfortunatly I live in a country where the effective treatment with marijuana is illegal.

I don't take Viagra nor do I see blue fog but I'm off to get a check up. Some tail lights create some interesting patterns indeed.

As far as visual arts go I know that Monet was virtually blind during the creation of many water lily murals.

btw Fuchs syndrome is the appearence of tiny bubbles in the cornea that can even change the shape of the eye resulting in varying focus.
Once it corrected my vision without the use of glasses but only for a matter of hours. Its benign but can slightly progress perhaps to the point where diffraction could occur.

Glaucoma is a very nasty and virtually symtomless disorder.

'Spikey glows around lights' is a reasonable description of myopia (near-sightedness). It's what I would see around lights, or the stars. For the 'rainbows', I say get thee to an eyedoctor, pronto.

I'm fortunate in that my opthalmologist is the same age as I, has the same degree of myopia I have, and now has the very beginnings of cataract formation as I have. He knows what to look for when I come in. There's no obvious problem from the cataracts yet; he said it will likely be five years before I begin to notice any deterioration in vision.

Donuel, I know you are a visual artist, as I am. Get those eyes looked after, as much can be done before things get serious. If you wear glasses, it could be as simple as a poorly ground set of lenses - I had a pair once which drove me mad, because they tinted everything slightly blue, and no one else could see it when I showed them the lenses. When my eye doctor tested them, he saw that they were indeed badly tempered, and were slightly tinted blue.

See an ophthmalogist (an MD specializing in eye care) NOW!! Don't fool around with this.

Have your eyes checked for Glaucoma immediately.

starting 6 months ago I see circular rainbows around bright light sources. I have seen spikey glows around lights for decades but the rainbows are a bit more transient. I don't think the eyes are dry but something is causing the added refraction be it morning or night.
I have wondered if Fuchs Syndrome could produce this refraction or if this is a symptom of cataract.
