How much do progressive lenses cost?

It would be wrong to say that the most expensive lens will definitely be the best lens for you. To summarize, in order to choose the right progressive lens, you need to consider various factors: .

There are a few factors to consider.

How much do pro­gres­sive lens­es cost? With the on­set of the first symp­toms of pres­by­opia, we in­evitably start think­ing about get­ting our first glass­es with pro­gres­sive lens­es so as to avoid the has­sle of hav­ing to keep chang­ing glass­es (for near and far vi­sion). When first ap­proach­ing the world of pro­gres­sive lens­es, there are a few fac­tors to con­sid­er. One of the first is the fear of not get­ting used to this new type of lens right away. This is be­cause, very of­ten, if you don’t take ac­count of a se­ries of pa­ra­me­ters, which we will dis­cuss be­low, us­ing a pro­gres­sive lens can cause headaches, dizzi­ness, blurred vi­sion, dis­tor­tions, or nau­sea. For this rea­son, op­ti­cians rec­om­mend im­me­di­ate­ly switch­ing to the use of pro­gres­sive lens­es as soon as the first signs of pres­by­opia start to arise.

The small­er the near-view cor­rec­tion, the faster you will adapt.

An­oth­er as­pect that may be of great con­cern in this tran­si­tion is the cost. But be­fore we look at a whole se­ries of fac­tors that can af­fect the cost of a pro­gres­sive lens, let’s fo­cus for a mo­ment on the char­ac­ter­is­tics of this type of lens.

**What is a pro­gres­sive lens? **

A pro­gres­sive lens is a cor­rec­tive lens that in­te­grates 3 cor­rec­tive pow­ers in a sin­gle lens, i.e. a near zone, a dis­tance zone, and an in­ter­me­di­ate zone. We can think of the in­te­ri­or por­tion of a pro­gres­sive lens as hav­ing a sort of “bot­tle­neck” area, known as the pro­gres­sive cor­ri­dor, which, de­pend­ing on the con­struc­tion pa­ra­me­ters of the lens, can be widened or nar­rowed in all ar­eas of vi­sion.

We can there­fore eas­i­ly see how this type of lens is good for some­one with pres­by­opia, be­cause they will no longer have to change glass­es to see up close or far away.

How are pro­gres­sive lens­es made?

The equip­ment used to con­struct these lens­es uses free-form tech­nol­o­gy. This tech­nol­o­gy, which in re­cent years has re­placed the more tra­di­tion­al tech­nique, makes use of an al­go­rithm to recre­ate the geom­e­try of the lens based on the pow­ers need­ed and oth­er spe­cif­ic pa­ra­me­ters. In the 1980s, a com­plex math­e­mat­i­cal al­go­rithm would take 3 hours to run. To­day, with the rise of in­for­ma­tion tech­nol­o­gy, the same cal­cu­la­tion takes just 3 sec­onds. When con­struct­ing a pro­gres­sive free-form lens, tiny “man­drels” chis­el the lens in 50,000 points in or­der to op­ti­mize its cur­va­ture and over­all geom­e­try. The more pre­cise the cal­cu­la­tion, the more pre­cise the geom­e­try of the lens and the less dis­tor­tion there will be in the tran­si­tion be­tween one vi­sion area and an­oth­er. The al­go­rithm used to con­struct the lens is de­rived from spe­cial soft­ware that dif­fer­en­ti­ates the var­i­ous types of lens­es de­vel­oped. Here at Di­v­el Italia, we de­vel­op the soft­ware for our lens­es in-house, to­geth­er with our Re­search and De­vel­op­ment team.

The more so­phis­ti­cat­ed and in­no­v­a­tive the soft­ware, the high­er the qual­i­ty of the pro­gres­sive lens.

This is one of the first fac­tors that af­fects the cost of a pro­gres­sive lens: PRO­DUC­TION QUAL­I­TY. Most lens man­u­fac­tur­ers of­fer var­i­ous types of pro­gres­sive lens­es un­der dif­fer­ent names. These pro­gres­sive lens­es dif­fer from one an­oth­er pri­mar­i­ly for the type of geom­e­try and the al­go­rithm used. The more so­phis­ti­cat­ed the geom­e­try, the more pre­cise the con­struc­tion of the lens will be, which re­duces the aber­ra­tion zones in the lens. Of­ten, top-of-the-line lens­es like our Aliena pro­gres­sives are the best be­cause they dis­trib­ute dis­tor­tions even­ly, there­by en­sur­ing vi­su­al com­fort and ver­sa­til­i­ty of use. This ease of adap­ta­tion jus­ti­fies the high­er price.

Nonethe­less, it would be wrong to say that the most ex­pen­sive lens will def­i­nite­ly be the best lens for you.

The qual­i­ty of the lens, as we’ve said, de­pends on many fac­tors.

The top-of-the-line lens­es cer­tain­ly rep­re­sent the max­i­mum tech­no­log­i­cal ex­pres­sion of their cat­e­go­ry, with the best dis­tri­b­u­tion and ho­mo­gene­ity or cor­rec­tive pow­er, and are very of­ten de­signed specif­i­cal­ly for the wear­er. But a mid-range lens like our A Clear could be a good so­lu­tion, too, as it rep­re­sents the ide­al com­pro­mise for first-time wear­ers of pro­gres­sive lens­es, be­cause they com­bine per­son­al­ized aes­thet­ics with op­ti­mal vi­sion in each area.

Or an op­ti­mal so­lu­tion could be a more stan­dard lens, like our Gem­i­ni, de­signed for those who spend many hours at the wheel, so no less func­tion­al than a high­er-end lens, but de­signed for a spe­cif­ic use. So, with the help of with your op­ti­cian, eval­u­ate the char­ac­ter­is­tics of the lens­es avail­able to you. A high-end lens may not be the most suit­able for your vi­su­al needs, and you may be able to spend a lit­tle less for a mid-range lens that is spe­cif­ic to your vi­sion needs. At the same time, sac­ri­fic­ing qual­i­ty in a lens just to save mon­ey may cause prob­lems in adapt­ing to your new pair of glass­es.

What else af­fects the cost of a pro­gres­sive lens?

COR­REC­TIVE POW­ER, of course. If you’ve been wear­ing glass­es for many years, you will have learned a bit about the dif­fer­ence be­tween re­frac­tive in­dices, lens ma­te­ri­als, and lens thick­ness­es. Gen­er­al­ly speak­ing, the high­er the re­frac­tive in­dex, the more ex­pen­sive the lens will be, to which we can then add the cost of any added coat­ings. So if you have a very high cor­rec­tive pow­er that re­quires a high re­frac­tive in­dex, to avoid dis­tor­tion, you can al­ready imag­ine how a pro­gres­sive lens will cost you more.

A fi­nal, but no less im­por­tant, as­pect that in­flu­ences the cost of a pro­gres­sive lens is the type of COAT­ING ap­plied.

The more com­plete the coat­ings, the more ex­pen­sive the lens will be.

Be­tween a lens treat­ed with a ba­sic coat­ing and one with more so­phis­ti­cat­ed coat­ings there can be up to €200 of dif­fer­ence per pair of lens­es.

So how do you choose the right coat­ing?

Based on your lifestyle, dis­cuss with your op­ti­cian which coat­ing is best for you. For ex­am­ple, if you work in an of­fice, opt for a blue-block coat­ing and avoid high-end scratch-re­sis­tance coat­ings or hard­en­ers. If, on the oth­er hand, you work in a dusty en­vi­ron­ment, in­vest in a good anti-sta­t­ic, oil-re­pel­lent coat­ing.

To sum­ma­rize, in or­der to choose the right pro­gres­sive lens, you need to con­sid­er the fol­low­ing fac­tors: - PRO­DUC­TION QUAL­I­TY OF THE PRO­GRES­SIVE LENS (e.g. top-of-the-line, mid-range, or stan­dard) - COR­REC­TIVE POW­ER and THICK­NESS - COAT­INGS AP­PLIED

As a rule of thumb, we could say that, de­pend­ing on the cor­rec­tive pow­er and coat­ings ap­plied, and with­out con­sid­er­ing spe­cial pro­mo­tions (Ital­ian range): - A pair of high-end lens­es should cost be­tween €600 and €1,200 - A pair of up­per mid-range lens­es should cost be­tween €500 and €800 - A pair of mid-range lens­es should cost be­tween €300 and €600

Al­ways re­mem­ber that, to en­sure you have a good ex­pe­ri­ence with pro­gres­sive lens­es, it is very im­por­tant to pro­vide the right pa­ra­me­ters for the frame to be used. Rely on your op­ti­cian, who will de­ter­mine the var­i­ous pa­ra­me­ters, in­clud­ing ver­tex dis­tance, wrap an­gle, frame height, and so on. Also pay at­ten­tion to the type of frame. Of­ten glass­es that are too small can com­pro­mise your field of vi­sion, and very wide, shield lens­es can in­crease the ar­eas of dis­tor­tion. Al­ways turn to an op­ti­cian you can trust!

The knowl­edge and ex­pe­ri­ence of your op­ti­cian are the most im­por­tant thing, but buy­ing a good pair of pro­gres­sive lens­es with care will cer­tain­ly change your view­ing ex­pe­ri­ence.
