Medical Forum / General / Vision / July 2005help selecting progressive lenses
I am newly presbyopic consumer with the following prescription: R: -5.75 -175 X 27 Add +1.25 L: -5.75 -200 X 160 Add +1.25 p.d 60/57 I have been looking at frames that are about 30 mm high with a fitting height of about 18-19 mm. Money is tight but good vision is a priority for me. I am considering the following (listed in increasing $$$): 1. Essilor Ovation 1.67 2. Seiko Proceed II 1.6 or Seiko Proceed II 1.67 3. Varilux Comfort 1.6 4. Varilux Comfort 1.67 Question 1: Since I am on a limited budget, I'm thinking of giving Ovation a try - good or bad idea? Question 2: Any comments on the lenses above given my Rx and frame? (I want good versatility for reading, computer use and good distance vision) Thanks. What are you using now (index)? If you are happy with a particular index, stick with it. You also might consider 2 pairs of single vision, or a lined bifocal, but if you go for a progressive, make sure you have a free redo warranty on them. w.stacy, o.d. > I am newly presbyopic consumer with the following prescription: > [quoted text clipped - 24 lines] > > Thanks. Currently wearing single vision, 9 yrs old, was the highest index available at that time. This will be my first pair of PALs. Just so that I understand, why do you ask about my current index? Thx. >I am newly presbyopic consumer with the following prescription: > [quoted text clipped - 24 lines] > > Thanks. 30mm frame height is marginal for the best possible vision. I would avoid the Essilor Ovation because it is mediocre design and your Rx is moderately high-powered. Essilor makes the premium Varilux line, and I would look at the Varilux Panamic or Liberty in addition to the Comfort, especially with such a short fitting height. Try Wal-Mart, Sams, or Costco if you want a premium lens but are very tight on money. Even if you have to pay the annual membership fee for Sams or Costco, it might be worth it. Yes I have costco membership but Essilor's Verilux panamic 1.67 is too much $ for me there ($479 with Alize coating). The Essilor Ovation costs about half as much for the same 1.67 index... Will this lens work if I choose a frame about another 2-3 mm higher/bigger, and a fitting height over 20? Given my Rx Add is only 1.25 Anyone got any experience with a roughly similar Rx, in the Ovation or Comfort or Seiko lenses?? > Yes I have costco membership but Essilor's Verilux panamic 1.67 is too > much $ for me there ($479 with Alize coating).

How much can you get those for at Costco? > Seiko makes good lenses. How much can you get those for at Costco? Sears has a July sale for $100 off on Seiko Proceed II. Without the sale, the Seiko is roughly the same as the Verilux. But Seiko Proceed II is a short corridor lens (like the verilux ellipse). My fitting height is bigger than the min fitting required for short corridor, so I wanted to avoid short corridor because of their inherent design limitations of which I've read (ie., narrow corridor, rapid progression, small read area, having to move head more to see)... Any comments on short corridor lenses, the Seiko Proceed II, and/or the regular Essilor Ovation? Thx.. Mark, you seem knowledgeable. Seiko Proceed II 1.67 currently costs $209 at sears plus AR coating $89. Costs less than Vailux comfort at costco. I'm green at this stuff, but Seiko seems to have a good rep. Have you had any experience in any capacity with Seiko and/or short corridor lenses... Also i was worried about getting a short corridor, and was leaning instead to selecting a frame that will fit a non-short corridor lens for me. Any comments? Thx again. > Mark, you seem knowledgeable. Seiko Proceed II 1.67 currently costs > $209 at sears plus AR coating $89.

Sorry, I am not an optician, just an informed and experienced consumer. I have never tried a short corridor lens. Sometimes Robert Martelbello posts on this forum and he is the most knowledgeable person I have encountered. >I am newly presbyopic consumer with the following prescription: > [quoted text clipped - 18 lines] >Question 1: Since I am on a limited budget, I'm thinking of giving >Ovation a try - good or bad idea? Esillor (Comfort-Ovation) uses an older 1.6 index monomer (type of plastic) that is heavier than Seiko's lens, so I would use the Proceed. Optical performance with this Rx is essentially the same for both. Given a limited budget I would take 1.67 index off the table because the reduction in thickness is not significant (10%). >Question 2: Any comments on the lenses above given my Rx and frame? (I >want good versatility for reading, computer use and good distance >vision) Intermediate vision (25" to 32") doesn't become a problem until the add power reaches about +1.75. Most standard corridor designs will work equally well with a 1.25 add. "Free form" or direct surfaced designs use atoric surfaces and should be considered when your budget allows. This design will increase the quality of vision off axis when there is moderate (your Rx) to high levels of astigmatism present. Examples are SolaOne, J&J Definity, Zeiss Individual, Seiko Super Proceed Internal, Rodenstock Impression ILT, Shamir Autograph, and Varilux Ipseo. These lenses (except the Definity) are also customized for the wearer's individual prescription, pantoscopic tilt, vertex distance, PD, and near working distance. However, none of this matters if the glasses are not fit by an experienced and thorough optician. >Thanks. Your welcome.

Robert, that was a real eye-opener (haha) about the atorics... Not good news for me huh. Never heard about atorics ever before your post. Just researched them a bit now... for example on optiboard (i found you're on there too) Can you tell if I will benefit from atoric lenses at all or a lot?? And WHY haven't ANY of the 4 optical shops I visited suggested these at all? (costco, sears, sams and an independant who had the best selection) Even my optometrist/opthamologist suggested an aspheric today - the Zeiss Gradal Top (he only carries Zeiss and he never mentioned the Individual). As it turns out, the Zeiss lens costs me less from him than the Seiko or Varilux at costco, because in my jurisdiction optometrists by law must sell lenses for only cost + $75 (you may have noticed that on OptiBoard)... mind you he charges a ransom for his eye exam and the coating! Because I am the ignorant laymen and he's the educated OD with the graffitti after his name, I am too shy to ask the OD why isn't he recommending the atoric!! I feel like I'd be challenging his competence. I emphasized I am budget-conscience, but the key to getting good value is getting the right item! Surely most opticians won't put me into something wrong - or will they?!! .... Because of your info above, now I'm thinking I may be unhappy with ANY aspheric!! Please help!!! >Thanks for all the good replies. > [quoted text clipped - 4 lines] > >Can you tell if I will benefit from atoric lenses at all or a lot?? The area of clear vision away from the lens center will be somewhat larger when an atoric lens is used with your moderate level of astigmatism. The stronger the astigmatism the greater the benefit. There would also be some reduction in thickness and weight compared to traditional designs. With the add power placed on the back of the lens instead of the front you can expect a slightly wider field of vision at the reading distance, particularly helpful when the add power is more than +1.75 or so. >And WHY haven't ANY of the 4 optical shops I visited suggested these at >all? (costco, sears, sams and an independant who had the best >selection) There is a much greater chance of finding an experienced, knowledgeable optician at a private office compared to the medium and large chains. >Even my optometrist/opthamologist suggested an aspheric today - the >Zeiss Gradal Top (he only carries Zeiss and he never mentioned the [quoted text clipped - 3 lines] >noticed that on OptiBoard)... mind you he charges a ransom for his eye >exam and the coating! All progressive addition lenses (PAL) use aspheric curves. Some PALs are fully aspheric, allowing the use of flatter curves to decrease the weight and thickness of the lens. >Because I am the ignorant laymen and he's the educated OD with the >graffitti after his name, I am too shy to ask the OD why isn't he >recommending the atoric!! I feel like I'd be challenging his >competence. Most doctors appreciate a reasonably intelligent question or two. You might want to write down your questions and take notes. >I emphasized I am budget-conscience, but the key to getting good value >is getting the right item! Surely most opticians won't put me into >something wrong - or will they?!! .... Yes, due to ignorance or because of financial incentives. That's less likely to occur in a private office. >Because of your info above, now I'm thinking I may be unhappy with ANY >aspheric!! Please help!!! 1. Very accurate and optimal lens positioning. 2. As close to a "text book" frame fit as cosmetics will allow. Get these two things right and you will be 90% of the way towards the best pair of glasses possible. Issues with weight, thickness, off-axis aberrations, and reflections can be dealt with by using advanced lens materials, designs, and coatings, but are not substitutes for good opticianry, and in actuality require more precision in the placement of the lens in front of the eyes than standard lens designs.
