Divel Coatings

What are the recommended coatings to make the glasses last longer?

What to ask your optician


To see clear­ly, you need the lens­es of your glass­es to be clean and in good con­di­tion at all times. This is why you should clean your eye­wear dai­ly us­ing a soft cloth and wa­ter, cleanser, or oth­er spe­cial clean­ing so­lu­tion or dis­in­fec­tant rec­om­mend­ed by your op­ti­cian.

Of course, the per­for­mance and dura­bil­i­ty of a lens also de­pends on the coat­ings that are ap­plied by your op­ti­cian of choice.

So how do you choose the right coat­ing for your lens­es?

To an­swer this ques­tion, we need to first con­sid­er what ex­ter­nal agents can im­pact the look and func­tion­ing of a cor­rec­tive lens.

GLARE: Glare can be caused by sun­light or oth­er nat­ur­al or ar­ti­fi­cial sources of light. Just think about how of­ten you get blind­ed by the head­lights of on­com­ing traf­fic when you’re at the wheel. This can be a prob­lem for some­one who doesn’t even wear glass­es, so it can be that much worse when wear­ing cor­rec­tive lens­es.

If your lens­es don’t have an ANTI-GLARE coat­ing, bright lights can cre­ate a “ghost­ing” ef­fect on the lens that in­ter­feres with your vi­sion. With the right lens coat­ing, you see more clear­ly and the lens is more trans­par­ent and more es­thet­i­cal­ly pleas­ing.

Even the most ba­sic lens treat­ments avail­able in­clude a ba­sic ANTI-GLARE coat­ing.

SCRATCH­ES: Scratch­es are a night­mare for any­one who wears glass­es. Af­ter spend­ing good mon­ey on a new pair of lens­es, the threat of scratch­ing those lens­es is al­ways right around the cor­ner. Plas­tic lens­es have al­most en­tire­ly tak­en the place of glass, de­spite be­ing more prone to scratch­ing, in part be­cause they pro­vide greater re­sis­tance to break­age.

But what can scratch a lens? Dust, first of all. Or drop­ping them onto a hard sur­face. Even clean­ing them with the wrong type of fab­ric, which is why we rec­om­mend nev­er us­ing your clothes or pa­per tis­sues!

All or­gan­ic lens­es sold to­day come with a HARD coat­ing on both sides of the lens in or­der to pro­tect them from dai­ly wear. There are also sev­er­al ex­tra coat­ings that can be re­quest­ed in or­der to lend even greater scratch re­sis­tance.

GRIME: When you think of a dirty lens, the first thing that comes to mind are the fin­ger­prints you leave when han­dling lens­es with dirty hands. But lens­es can also col­lect grime when work­ing in a damp, dusty en­vi­ron­ment.

To pro­tect your lens­es un­der such cir­cum­stances, your op­ti­cian will al­ways rec­om­mend an OIL-RE­PEL­LENT coat­ing to help keep your lens­es clean.

LIQ­UIDS: In ad­di­tion to fin­ger­prints and oth­er grime, wa­ter is also a threat to your lens­es, so there are WA­TER-RE­PEL­LENT coat­ings that help keep wa­ter and oth­er liq­uids from de­posit­ing on the lens.

DUST: In ad­di­tion to caus­ing mi­cro-scratch­es on the sur­face of the lens, dust can col­lect on your lens­es and af­fect your vi­sion. For these cas­es, you can ap­ply an ANTI-STA­T­IC coat­ing to min­i­mize the amount of dust that sticks to the lens.

UV LIGHT: This is more of a threat to your eyes than to your lens­es and can cause ir­re­versible dam­age to your vi­sion. This is why a coat­ing that pro­vides UV PRO­TEC­TION is of­ten rec­om­mend­ed, par­tic­u­lar­ly if you work out­doors or en­joy lots of out­door ac­tiv­i­ties. UV pro­tec­tion can also be pro­vid­ed by the lens ma­te­r­i­al it­self in many cor­rec­tive in­dex­es.

It is also im­por­tant to re­mem­ber, how­ev­er, that UV light comes from the sun and can cause the oth­er coat­ings to de­te­ri­o­rate if you do not treat your glass­es prop­er­ly. For ex­am­ple, we high­ly rec­om­mend nev­er leav­ing your glass­es or sun­glass­es in the car or oth­er­wise ex­posed to a heat source.

BLUE LIGHT: This, too, is a threat to your eyes and can be avoid­ed with ei­ther coat­ings or lens ma­te­ri­als that pro­tect against BLUE LIGHT of up to 420 nanome­ters.

Which coat­ings does Di­v­el Italia rec­om­mend­ed in or­der to ex­tend the life of a lens?

Coat­ings avail­able with Di­v­el Italia in­clude:

  • HARD

HARD (H) Scratch re­sis­tance

It gives your lens­es greater pro­tec­tion against scratch­ing and gen­er­al wear and tear than our HARD coat­ing thanks, above all, to its ANTI-STA­T­IC lay­er, which pre­vents dust from set­tling on the lens. There is also a hy­dropho­bic lay­er that en­ables wa­ter and grime to slide off the sur­face of the lens, so you won’t risk ru­in­ing your lens­es when try­ing to clean off hard-to-re­move dirt.

SILKEN WHITE (S white) Scratch re­sis­tance, su­per anti-glare, anti-sta­t­ic, oil and wa­ter-re­pel­lent, ex­tra trans­paren­cy

Of course, to en­sure the dura­bil­i­ty and per­for­mance of this coat­ing, in ad­di­tion to the care and clean­ing men­tioned above, you also should:

  1. Avoid leav­ing your glass­es in the car, as sun­light can weak­en the coat­ing;

  2. Not use eye­wear re­tain­ers to hang your glass­es around your neck. These are not very safe, and your glass­es can come into con­tact with just about any­thing;

  3. Not leave your glass­es on top of our head, as they can fall and get dam­aged or mis­shapen;

  4. Take off your glass­es be­fore us­ing hair­spray, per­fume or cologne, as the al­co­hol con­tent could harm the lens­es and the frames;

  5. Al­ways store your eye­wear in a hard-shell case.
