Medical Forum / General / Vision / March 2007Correcting cyl in a wraparound frame??
Hi! So ... after a successful fitting with the Boston Scleral Lens device, I'm left with a smidgen of sphere OD and a smattering of lenticular cyl OU* which--at this point--the Boston Foundation for Sight can't correct. The corneal portion is zero'd out quite nicely. I'm now: OD +0.50 -1.25 x090 ADD +1.75 OS pl -1.25 x090 ADD +1.75 The sclerals do a good job of protecting the dry eye ... for as much as they cover. Still quite vulnerable on the unprotected parts. Bought the first pair of over-Rx glasses today. ...Single vision - distance only ...Transitions photochromic Seem okay, but ... without a doubt, they ain't gonna' cut it for hiking, biking, running, etc. Definitely need close-fitting wraparounds. Ideally, I'd buy/convert something like my Panoptx frames (foam gasket). BUT ... Ye Olde Chaine Store Optical Shoppe tells me that you can't put cyl into that kind of wraparound frame--not even in a close- fitting non-gasketed frame like an Oakley (my default shade). True?? If so, I'm in a very big "Yikes!" position here. I may need that sort of protection even for things like grocery shopping, movies, air- conditioned/heated buildings, or ... certainly if I still aspire to move to Colorado (which simply may not happen if this bit is insoluble). A quick check showed: - Panoptx' order form indicates "Our technicians precisely grind Rx lenses for prescriptions +3.00/-3.00D. Ranges to -5.00D are available with our Rx "Adaptor". Sport bifocals are also available." It also includes the CYL line on the Rx portion. BUT ... it doesn't specifically say that their wrapped lenses can be made with cyl correction; - Oakley's site gave me no clear indication vis-a-vis its wraparound frames - Wiley-X's site seems to allow cyl when entering parameters for online ordering. No idea, though, if they'd kick it back as not possible after the ordering process.... What are my options? At a minimum, wrap frames are a must. To do the things I really want to do, then something like Panoptx/Wiley-X is an absolute must. It's NOT important that my wraparounds be bifocal. In fact, I'm just going to use old OTC readers for anything near until further notice (had to do /something/ to simplify, huh?) Anything? Many thanks.... Neil * Ye Olde Chaine Store Optical Shoppe noted my PD monocularly, as OD 27.5 OS 26.0 [Can these be summed to achieve a binocular PD, or isn't it that simple?] Neil-good to hear the scleral lenses are working out. Check out this website: http://www.rudyprojectusa.com/products/sunglasses/styles/perception.htm# Their sports wraparound sunglasses have the option of a smaller Rx insert, which fits inside the frame--probably could get that done at a local optical shop. Seems like a good idea. You could get a decent lens material (not polycarb) for the Rx. But they don't offer the foam moisture-barrier in the Rx-able frames. Maybe there's a dealer near you where you could try some on. Good luck, C66 On Mar 11, 9:41 pm, callimic...@yahoo.com wrote: Rudy-Project: >But they don't offer the foam > moisture-barrier in the Rx-able frames. I just had an idea that might work for a foam barrier. You know those foam linings that are sold for TranquilEyes? Seems like you could try to find a pair of Rx-able wrap-around frames that had the same shape as the foam. You could make some small holes in the foam for ventilation, if needed.

I was hoping, however, that Lenscrafters was simply wrong ... or worse. Sounds like they were. Ideal would be something that's ready-made, no mods required. The Rudy Projects (and Bolles, and others that I eventually found) ARE good sunglasses and should work for the "low speed needs," but ... I'm going to get my Panoptx converted to prescription ... and be glad for it. It's not so much a moisture barrier that I need. Rather, it's that last degree of protection against the wind. Without it, even close- fitting NON-gasketed glasses seem to create a swirling eddy of wind behind the frames when I'm cycling. A Bad Thing, to be sure. The Panoptx CAN serve as low-speed glasses, if necessary. The Oakleys, Rudy Projects, etc., -- in my case -- can't effectively be pressed into "high-speed duty." Thanks much, again. Neil >Hi! > [quoted text clipped - 24 lines] > >True?? Nope. Assuming a twenty degree horizontal tilt on an eight base, the compensated (what the lab would grind to get the correct Rx) is +.48 -1.14 x 90 with .36^ BI.

Kbco makes a polarized lens in an eight base that is tweaked (multiple degrees of asphericity to match the Rx) reduced off-axis blur, although at this power any lens design should suffice. Try both the brown and the gray tints. Most folks prefer the brown. >Anything? > [quoted text clipped - 8 lines] >[Can these be summed to achieve a binocular PD, or isn't it that >simple?] Use the monocular PD, especially if the lens is aspheric. Lower the OC .5mm for every one degree of Panto (vertical tilt).

For the first time in my life, I have a near-nothing Rx, so ... I wasn't even /thinking/ about light weight. Was there something else about the Silhouettes that you were thinking about, too? What I got for pair #1 (all-around wear when wind protection needs are low) was a Ray-Ban 3162 BLCK9/52. http://www.framesdirect.com/framesfp/RayBan-tclbqg/lb.html Any reason you might recommend the Silhouette above that, for example? > >It's NOT important that my wraparounds be bifocal.

Most > folks prefer the brown. That's great, Robert. Many thanks for that. Sounds like a pretty bum steer by the Chaine Store Optical Shoppe (gee...). Also sounds like a /better/ optical shop should be able to simply order a replacement, Rx lens for my /existing/ Panoptx frame. That's a good thing. > >* Ye Olde Chaine Store Optical Shoppe noted my PD monocularly, as > [quoted text clipped - 6 lines] > Use the monocular PD, especially if the lens is aspheric.

See the above. >Also sounds like >a /better/ optical shop should be able to simply order a replacement, >Rx lens for my /existing/ Panoptx frame. That's a good thing. Yup. If the frame is full metal they'll need to have the frame in hand to assure a proper lens fit. One concern with single lens replacements and Transitions is that the lens color wears out with age. If they are more than a year old or so you'll need to replace both for a good match. The tint in polarized lenses varies with different manufacturers- it's important that the optician uses the same manufacturer (lens company, not the lab) for single lens replacements. Even then, there will be variances in density and hue from the same manufacturer over time. It's usually best to replace in pairs for the above reasons. >Thanks again, Robert.

I seem to need four pairs of glasses (another reason that eye pro's like me!): Wraparound glasses for "not moving too fast" distance-vision situations: 1....photochromic/light tinted for evening 2....tinted, polarized, AR coated for daytime (eg, driving) Hoping to convert my existing Oakleys for one of these Wraparound, gasketed glasses for active sports, distance-vision: 3....photochromic, polarized, AR coated for all-around Hoping to convert my existing Panoptx for these Wraparound (eg, Silhouette) glasses for near-vision tasks ....photochromic, polarized, AR coated--either progressive or single- vision with the +1.75 ADD This is, literally, four pairs of glasses. While that's not the end of the world, I'd be open to consolidation if there's a practical way to do it. Could make the "high-speed" gasketed wraps my primary glasses, but ... would prefer not to look to extra-terrestrial ALL the time.... I've NEVER worn bifocals before, and am slightly concerned about trying to adapt to them when, for example, riding a bicycle at 40km/ hr. Also, since the underlying accommodative and binocular stuff is still alive and well, I'm not likely to do any prolonged near work to speak of, so ... separate near glasses might be just fine for me. One more thing ... if you please. The sclerals have their own funky optics. I get the ghosting and halo sort of effects a chunk worse than scl's. Has anybody had much luck with wavefront spectacles? It seems possible to do a wavefront scan OVER the sclerals, then Rx from there. PRE-scleral wavefront showed 3.2% HOA (RMS error: 0.32 OU) Any thoughts?? Thanks again! Neil > > Neil Brooks schreef: > [quoted text clipped - 78 lines] > Thanks again! > Neil Sorry. Little foggy this morning. That seems to add up to THREE pairs of glasses ;-) >Neil look at the Adidas website. They're made by Silhouette. My experience has been they're slightly lower quality then the regular Silhouette line, although they make some nice looking sports/sunglasses, and the inserts are great for strong Rxs.

I fired off a customer service e-mail to Ye Olde -- aw, screw it -- Lenscrafters -- telling them that I was disappointed that their manager told me that my lens could NOT BE MADE--rather than telling me that Lenscrafters simply couldn't do it. I'll likely avail myself of their (only reason to go there) 30-day guarantee, then find a better local optician who carries the Silhouette line.

The best I heard was (forgive me) that the whole affair was a real boon to some elderly people who formerly believed that incontinence would keep them OUT of the space program ;-) Glasses update: Visited New Optometrist's office (good, bright, geeky guy. My favorite kind....). I'm starting out with two pairs of glasses. We'll take it from there: 1) Silhouettes w/iZon PAL lenses (are you hearing the sound of cash registers, Robert? I know I am....) 2) My Oakley frames will be given new, grey, Rx lenses w/back-surface AR and polarization. I'm ... uh ... going to avail myself of the Lenscrafters guarantee. Thanks again for your help. The Silhouettes do, indeed, look cool (actually, I can't even see them ;-)). Hope the iZons are actually of some benefit. A tad skeptical, but .... that's just me. >> >[comment about recent damage to NASA's credibility done by one whacked- >> >out astronaut intentionally omitted]. >> >> They've taken "cat fight" to new heights. I made that one up on the fly. Jon Stewart had a lot of fun with this. >The best I heard was (forgive me) that the whole affair was a real >boon to some elderly people who formerly believed that incontinence >would keep them OUT of the space program ;-) Good one! Sounds like Letterman's work. >Glasses update: > >Visited New Optometrist's office (good, bright, geeky guy. My >favorite kind....). My best man (another optician) spent an evening (and most of the next morning) with Hunter Thompson when he was in town for a speech at the university about 15 years ago. On my best day I could barely keep up with him (whiskey-wise) so I felt better when I heard he held his own with Thompson. >I'm starting out with two pairs of glasses.

What would be the reason? The only thing I can think of is you would increase light transmission, which you'd only want if the patient thought the regular ones were too dark... Lots of sunglasses in fact have gradient or full mirrors on the front (the exact opposite of an AR coating) to decrease transmission further... w.stacy, o.d. >>It wouldn't hurt to AR coat the front surface. >> [quoted text clipped - 6 lines] > >w.stacy, o.d. They look a lot nicer (it costs as much to do one side as it does both sides). I used to worry about the durability of the front surface, but the coatings are so robust now, I don't hesitate to coat both sides. I do get a lot of complaints from folks who do not like their sunglasses (not from me) because they were too dark. That's one of the reasons I now recommend brown instead of gray polarized sun lenses. I'm very light sensitive and find the coated brown polarized plenty dark even when in direct sun and near or over water. My clients agree- they say it feels like they're not wearing sunglasses, and that the vision seems sharper and more natural. That's assuming they're fit properly of course, with good coverage at the top and sides, and sitting very close to the eyes. The result is my clients wear their sunglasses more frequently, and tend to update the sun Rx lenses more often. :) Regards, Robert Martellaro ~~~~~~~~~~~~~~~~~~ Optician/Owner Roberts Optical Wauwatosa Wi. ~~~~~~~~~~~~~~~~~~ "Science is a way of trying not to fool yourself." - Richard Feynman |
