Well, things just keep getting more unusual. As I mentioned in my first post on presbyopia, dry eye and diabetes, I had to have a re-grind for an astigmatism error my eye doc’s tech made in my first set of lenses. It took 4.5 weeks to get the re-grind set in. I also ordered a second set of lenses with a slightly different sphere power. My original post explains why I needed the additional lenses.
After I got the new correction for the astigmatism back, it was better than my first right eye correction, but my right eye was still off. After a week or so with the correction on the Superfocus glasses, I decided to try an experiment. I had an extra left lens which didn’t have any cylinder or axis correction in it, and the sphere power was very close to my right eye. I put the extra left lens in the right side of the Superfocus glasses and my vision got reasonably clear in my right eye and my binocular vision was noticeably better. Interesting–and frustrating!
With an astigmatism correction, it’s almost impossible to get really sharp vision correction because astigmatism compensation is not objectively measured in the eye doc’s office, it’s subjectively estimated by experimentation and patient feedback. Since the light and viewing conditions outside of the exam room are very different, astigmatism corrections are generally imperfect.
After seeing the world through my right eye without an astigmatism correction, I decided to consult with a 3rd eye doc who does his own refractions rather than letting tech’s do them. I explained my experiment to him and asked him to start all over with the refractory exam in my right eye and not assume that I had an astigmatism that was the base starting point of the exam. After 30 minutes of going through a lot of settings on his phoropter, he concluded my vision was better with no correction for an astigmatism. I would have liked a wavefront exam but he didn’t do that.
So I ordered a third set of lens for my Superfocus glasses today. I will have a few extra lens if anyone needs some. Hopefully, removing the cylinder and axis corrections will clear up my vision. 3rd Eye doc says it will take a week or so to know the full extent of the correction. He thinks my right eye got worse during the day because it was straining to re-correct for the astigmatism offset. He thinks the astigmatism error got into the prescription 4 or 5 years ago, but up until 2 years ago, my eye muscles were still strong enough to offset it. It was a mild correction. If it had been a significant one, my eyes couldn’t have coped with it. I hope he is right. If this doesn’t work then the wavefront exam is next.
Once again Debbie D went out of her way to help with my lens. On my last order in November for the re-grind and extra lens, it looked like it was going to take 6 weeks for the re-grind and 8 weeks for the second set of lenses because of various delays in production. Debbie called and once she knew what had happened she got the time line back on track. I really appreciate Debbie’s help. She is first class. As I’ve said before, for me she has been a major factor in the positive feelings I have about the company. She is helping me get this new set of plano lens, along with my second pair of Superfocus glasses.
Unfortunately, Superfocus LLC is taking a long time to both ship the glasses initially and process new lens orders. Typically it takes me 5 to 10 days to get in new lenses for my progressives. Four to six weeks for a pair of new Superfocus lenses is well above the industry standard. Eight weeks and longer to get the initial order out is also on the far side of reasonable. I hope the company gets their manufacturing house in order before too long because other competition is coming to the market. The company has done a great job of selling the glasses, and the customers that have them like them. But it appears that maybe they’ve out sold their ability to produce the glasses, which is a major potential problem. (I’ve spoken with a couple of members of the Superfocus LLC management team, including Adrian Koppes, the CEO. I think they are committed to reducing the fulfillment times. The longer lead times may continue for three or so more months, but then it should start to decline. That’s my best guess based on the information I have. I hope they are able to bring it down to within 4 weeks.)
The new lenses with the new astigmatism adjust are much better than the first pair and even though they’re still have an astigmatism correction which 3rd Eye Docs says I don’t need. Even with the astigmatism correction they have helped me to manage my vision issues even better than before, so I am pleased with that. I’ve recommended and demonstrated the glasses to several opticians, ophthalmologists, and a whole lot of other people with problems similar to mine.
A second set of lens only cost $79 (the $29 shipping charge seems a bit excessive) so buying extra sets with different scripts for different applications isn’t a problem. I don’t particularly like the airline pricing scheme either. Extra charges for the proper size temples is a very uncommon practice also.
As I said, I like the Superfocus glasses and I have ordered a second pair. I need a backup in case the first pair breaks or needs repair. If Superfocus LLC finds a way to improve these, I’ll upgrade. I will use these daily until a better technology comes along.
The bottom line is if you’ve got the patience to handle the long shipping times, these glasses might benefit you just like they have me. It’s been well worth it for me.
(I found 4th Eye Doc who has a Wavefront machine, so that exam is next. Once my eyes are completely mapped, it will either confirm that my right has no astigmatism, or that there are other attributes I need to have corrected. If there are, I’ll have a lens ground to match my eye map and how light bounces off my retina. That should be interesting. The Wavefront machine might find I do have an astigmatism, and maybe a third arm too.)
