Contact Lenses halos

softlenses3 · #1 (**permalink**) 07-25-2010, 09:13 PM

I've began wearing contact lenses 4 years ago. When I wear glasses my eyesight is normal but when I wear contact lenses everything is normal when I'm outside in the daytime but when I'm indoors or outside at night. I see rings around objects. I have been to many doctors they increased the area of the lenses to cover more of my pupil but this failed. I was thinking that I had a astigmatism but my doctor said that I don't. What do you guys think could this be due to a astigmatism by the way I am nearsighted and my vision is poor -13.00.

Hi softlens3. Welcome to Lens 101.

I read your story and I right away I thought of another post I saw here on Lens 101 about halos. That site also says that this is usually caused by a contact lens that has too small a diameter. Maybe your contact lenses are still too big. I don't know what else can cause these halos.
Here's the thread that talks about halos at night: http://www.lens101.com/air-optix-astigmatism/30171-air-optix-astigmatism-after-dark.html

The thread doesn't really have a resolution, but maybe you can find some more clues to help you solve this mystery.

I heard the same thing, Aaron. If you're experiencing halos in your vision, it's probably due to a contact lens that has too small of an optic zone or a pupil that's too small.

I've heard the same thing, Betty. If you're wearing clear contact lenses, the optic zone is too small. If they're colored contacts, then the pupil hole is too small.

Wow. Cool eye picture HVAC. It looks liked a domed crater on some distant world.

I thought it looked pretty cool too, and more importantly, clearly illustrated the point.

So should the contact lens cover the central, mid or peripheral zones? Or maybe all three?

That's always a plus . . .

I would say, probably all three zones should be covered by a contact lens. Even the so-called "peripheral zone" doesn't include the entire cornea.
