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.
