Medical Forum / General / Vision / January 2006Contact lenses not well adjusted
I was disappointed when I received my new disposable contact lenses because I see blurry from the left eye. I can still read, but sometimes with difficulty. In 6 months I will go for another eye exam, but will visit a different doctor this time. Should I go as soon as possible instead? I don't have headaches or any other obvious problems. Thanks. >I was disappointed when I received my new disposable contact lenses >because I see blurry from the left eye. I can still read, but sometimes >with difficulty.

Are you happy with blurry vision? If not, I would go back to the prescribing doctor and discuss the problem with him/her. Not much downside to that.... Happy New Year!

The most annoying thing is when I need to read something in a dark place like in the car or at the restaurant, or at work where I look at a computer screen all day.

I have a similar problem. The doc finally arrived at a good prescription, but the contacts that I ordered are all different. I conclude that the manufacturing tolerances are far sloppier than my eyes demand, but I have no actual confirmation of that. Out of 4 pair of lenses, 1 is good, 2 are bad in different ways, and the third is unknown. I went back to the doc last week, who is ordering me something different. My previous lenses were Cooper Preference Torics (6 or 8 out of 12 lenses bad). These are Sunsoft Multiples Torics (4 out of 6 bad, so far). Nothing is ever easy. >> I was disappointed when I received my new disposable contact lenses >> because I see blurry from the left eye. I can still read, but sometimes >> with difficulty.

ANSI Z80.20 and ISO 8321 standards lay down tolerances for contact lens power. For 0.00D to 10.00D, the tolerance is +/- 0.25D, and above 10.00 the tolerance is 0.50D. In manufacture, lenses that fall outside of these tolerances wil probably be reassigned. In the US certainly, incorrect labelling of lens power is a recall situation >> I have a similar problem.

We've been working on fitting my trifocals for months now and we're making .25 adjustments. Doc was even considering a .125 this last time if they could do it... Maybe that's why some of the adjustments have bought some surprising results. By the standards we could order a -.25 difference and end up with a -.75 actual. I would hope with computer controlled manufacture that, in practice, tolerances are much tighter than the standards. -Quick >> I have a similar problem.

I [quoted text clipped - 10 lines] > In the US certainly, incorrect labelling of lens power is a recall > situation My suspicion centers on the angle of the astigmatism correction (-2.25x80 and 90). I could bring the right lens of the first bad pair into the proper position by pulling on the skin around my eyelids in various ways. It always bounced back within seconds, though. The right lens of the second bad pair couldn't be repositioned correctly by anything I tried to do in the morning before I took it out. Sunsoft Multiples Toric 8.5 R: +3.50 -2.25 x 90 (6/27/05) L: +5.75 -2.25 x 80 (6/20/05) I had a similar problem with Cooper Frequency 55 Torics.
