Biofinity blurry for nearby objects

ilove · #1 (**permalink**) 01-28-2011, 11:23 PM

I am on my trial pair for Biofinity.
I am wearing regular Biofinity on my right eye (SiH48) and Biofinity Toric (Comfilcon A 168) on my left eye.

I absolutely love them, great fit and all, but I am having blurring issues with focusing on nearby objects. Far away vision is very crisp. Anyone had the same issue here?

My optician thinks this is due to the lenses having too high a power for my eyes, but upon trying different combination of powers, both far away and nearby vision got blurry.

Couple people on these boards who confessed they had the same problem suggested the lenses might be defective. Could this be the case? Is it common to run into defective Biofinity lenses?

I had almost zero success with other lenses and I would really like Biofinity to work.

I'm 28 by the way,

and my spectacle prescription is

OS -5.25 -1.25 175
OD -5.75 -0.50 165

When using the contacts that give you good distance vision, does the near-vision blurriness occur in both eyes, or just one? If it's only the toric lens that results in blurriness up close, that suggests it may not be rotating ideally for your eye, so perhaps a different angle would help. That's just a wild guess - I'm not an eye care professional.

Otherwise, the obvious thing to do is to try a different brand and see if you get different results. It's not rocket science - not in the sense of being easier, but in the sense of being less predictable than getting a rocket to the moon. Some experimentation is necessary.

Good answer GaryFx. Welcome to Lens 101.

I had the same idea about that toric lens rotating the wrong way. I agree that you should try a different brand, ilove.

I covered each eye to check which side was giving me the blurries.

I definitely did NOT feel that the toric side was particularly worse than the other.

I got prescribed lenses with the following powers

Right -5.75
Left -5.00 -0.75 170

Hi there, ilove.

It sounds like your eye doctor did everything he or she could to try different lenses to get the best vision possible. Maybe that's just the best you can get. I don't think the lenses are defective, just not the best for your eyes.

You say you're 28 years old, and thats a little young to be wearing reading glasses. Most people start wearing those around the age of 40, so you've got a ways to go before you need to start thinking about that. Have you considered bifocal contact lenses? Hopefully it won't come to that. Maybe you just need to tweak the prescription on the Biofinity lenses a little more. Let us know if you find a solution, okay?

Thanks everyone for your ideas. So I found out what my problem was, and it was actually my non-toric eye (right eye). My toric lens is crisp for both far and near. I will have to tweak the prescription of my right eye to find the optimal combo. My question is,

could the problem be caused by the -0.50 cylinder astigmatism in my right eye that is left uncorrected?

GaryFx · #8 (**permalink**) 02-06-2011, 08:07 AM

It could well be. Often a half diopter of astigmatism is considered small enough to ignore. Toric contacts generally don't come with cylinder corrections that small. Even with a correction of 0.75 diopters, people will sometimes find spherical lenses good enough to be worth the cost savings. But everyone is different, and because that works for many people doesn't mean it will work for you.

It's conceivable that a slightly stronger prescription, say -6.00, might work for you, since your prescription implies a correction of -6.25 diopters on the 165 axis. Assuming your doctor, like mine, is willing to let you have a trial lens like this, it's worth the effort.

If you still can't find soft lenses that work, then the next step is to look at RGP (rigid gas permeable) lenses, since they are often better at correcting astigmatism.

Good answer, GaryFx. I'm glad you decided to join us at Lens 101.

What do you think, ilove?

Ok, so I went back to my optician and she ordered Biofinity toric lenses for my right eye as well. In the mean time, she gave me a PureVision toric to try while waiting for Biofinity toric to arrive, and I must say, wearing toric lenses in both eyes the vision was MUCH better. YAY

Yay ilove. I'm glad your temporary Purevision lenses work so well. I hope you'll let us know how you like the Biofinity lenses as well. If you wear sunglasses or eyeglasses, Lens 101 has categories for those, too.

That's right, Eagleye. We need more people in the sunglasses and eyeglasses sections of Lens 101. There are a lot of questions there that need some answers.

Were you wearing Purevision Toric in both eyes while you were waiting for the Biofinity lenses?

Let's tell all those people out there and spread the word, Englishteacher1.

I just checked the sunglasses section and it doesn't look like anyone has been there since March. So it's not like it's been two years, but we definitely need to get more people contributing there.
