Long Time Oasys user... seeing halo's now?

TCU34 · #1 (**permalink**) 08-23-2011, 11:35 PM

Hi all. Nice forum you have here, lots of neat info.

So here is my dilemma...

I've been wearing contacts for 9.5 years (since I was 15 years old). Started off with daily's at like -1.0 in each eye. I moved to Acuvue 2's as. Then as my eyes got worse I moved to the Oasys contacts when they first came out, 2006-2007 perhaps? I have always worn them in month long increments (for some reason thought they were monthlies until a year ago so I just kept doing it) but I take them out every single night and I clean them with clear care. Needless to say I've been pretty happy and I rarely ever notice them.

Well this past Saturday I went to my normal eye doctor's office but I had a new Dr. seeing it was Saturday the normal lady was off. I knew that my left eye had pretty much stabilized at -3.00 but over the past two years my right has dropped to -3.25 and I figured it needed even more adjusting this time. So he dropped me to -3.50 and got me seeing 20/15. He sent me on my way and I was pretty happy with my results.

That is until the last two evenings when I've done night time driving. In my right eye I'm seeing terrible "halos" in the lights I look at. Its almost like an extension of the light itself, and VERY irritating. Obviously the only thing that is changed, to my knowledge, is my prescription from -3.25 to -3.5. But seeing my prescription has changed 6 or 7 times over the years and I've never experienced this, I'm thinking that might not be the reason.

The ONLY thing I can think that happened is that maybe he gave me the wrong BC on my trial pair? My old ones are 8.4, maybe he gave me an 8.8? I don't know much about contacts but with the little research I've done this is all I can think of. I'm obviously going to call them tomorrow, but is this even a reasonable excuse for them to halo?

Thanks in advance!

I found another post on Lens 101 about halos here: http://www.lens101.com/gas-permeable-contact-lenses/737-halo-effect.html

This is what is says: "Halos usually are related to optic zone size, overall diameter and pupil size. . . excessive halos are solved by increasing the size of the lens."

So it's probably the diameter rather than the base curve that is causing those halos.

Did you say you were wearing Acuvue Oasys? If that's the case you may need to try something else because those only come in a diameter of 14.0 mm. Hopefully your regular doctor can fix this for you during the week.

Interesting... I actually just found the used package of my current contacts. Sure enough, the B.C. and DIA are the same as they have always been 8.4 and 14.0. I really don't see how an increse from 3.25 to 3.5 would cause this halo effect. It is litteraly the exact same contact.

I don't know why a change in prescription would cause halos either. Have you been able to see your regular doctor again yet? Perhaps the substitute made a mistake. Keep us advised on your situation. People like me usually go to this site and scan for new posts first of all.

Finally, I'm confused. The last thing you said was "it was literally the exact same contact." Did you put an old contact lens back in your eye??

So the diameter hasn't changed, yet now you're seeing halos that you haven't seen before. Right?

I think maybe TCU34 used the word "literally" incorrectly. Reading over the post I think he or she probably should have said "the base curve and diameter were exactly the same." He/She did mention that the power was changed from 3.25 to 3.5. So you couldn't even say "lenses with the exact same parameters."

That's extremely common. My favorite example of that would be "That was so funny! I died, I literally died."

Yeah, that statement can't possibly be true.

So can we get back to halos now?

Well once I had halos, and I finally realized it was probably because I had put drops in my eyes before I inserted Contacts, then drops afterwards. So for a while I felt that all that extra fluid caused the appearance of halos especially when viewing sources of light.

Couldn't be that simple, I guess, if it occurs every time with a certain lens?

So did you put fewer drops in? Did you stop putting drops in before you put in the contacts or after?

Was the "extra fluid" caused by the drops you put in before or after you inserted the contact lenses?
