As an eyeglass customer, have you ever asked yourself this question, “Can I add anti-reflective coating to my glasses after purchase?” It’s quite possible that you have. It is not uncommon for consumers to go down the checklist of options for a new pair of lenses and opt out of the anti-reflective coating in order to economize. However, it also does not take long wearing the new eyeglasses for many to regret that decision. In some cases a do-over is possible.
Under certain conditions it is possible to apply an anti-reflective coating on the lenses of a pair of eyeglasses that have already been purchased. However, it is not recommended and there are certain factors that should be seriously considered before making this decision:
- It may cost more after the fact than if the anti-reflective coating had been applied at the time of lens manufacture.
- If within a time window guarantee, it may be possible to upgrade the lens at the original price of the anti-reflective coating option or have new lenses made.
- Because the lens has been exposed to skin oils and is not factory “fresh”, the coating may not adhere well which could shorten the effective lifespan of the coating.
- If any scratch is present, application of an anti-reflective coating will magnify it. In such cases it would not be recommended to apply an anti-reflective coating.
- The highest quality coatings may not be available due to the fact that the application technology requires it be applied at the time that the lens is cut. Consumers may have to opt for a more inferior anti-reflective coating after the fact.
The Best Advice
The top recommendations from experts in the eyewear industry all agree that for the highest quality lens and anti-reflective coating, it should be applied at the time the lenses are cut. If the coating is to be applied after eyewear purchase, it is best to return within a guarantee time period and have lenses re-made, paying the difference for upgrading to include the anti-reflective coating option. However, if a consumer’s guarantee period has expired, it is possible to apply a lower quality anti-reflective coating to a lens that is scratch free in some cases. Please keep in mind that because of the questionability of quality, in many cases an eyewear provider may refuse to provide service to apply an anti-reflective coating to lenses that have already been cut. They may only offer the option of completely remaking lenses and having the anti-reflective coating applied at the time of lens manufacture.
To better understand the limitations of applying an anti-reflective coating after eyewear purchase, consumers need to understand the process of how the coating is applied when lenses are cut. First, the lenses are meticulously cleaned and inspected microscopically for the tiniest smudge, scratch, or residue. Lenses are subjected to high tech cleaning processes multiple times in order to remove any possible contaminants.
After washing, lenses are then dried in heat controlled ovens to remove all moisture and accumulated gases from their surfaces. After being thoroughly cleaned and dried, lenses are placed in racks in a vacuum sealed chamber for the application process of the anti-reflective coating. Lenses are bombarded with electrons that vaporize and then adhere to their surface to form a microscopic layer.
Why Opt For AR
Anti-reflective coatings are advised for people who spend several hours in front of a computer screen. They also make night driving safer by eliminating the glare of artificial light. If eyewear has a mirrored lens, an anti-reflective coating on the backside of the lens is practically a necessity. There are different types of coatings to choose from and can be recognized by brand names. Crizal is considered industry wide as the premium brand of anti-reflective coatings.
