    If the coating is scratched, chances are the lenses are scratched as well, particularly if they are made of plastic. Lenses can be recoated, but the old coating must first be removed, by polishing the lens with an abrasive or chemically removing the coating(s).

    The industry itself is not particularly oriented towards providing this type of service, but is quite efficient at delivering new lenses to customers. Repair services are not as economical or readily available, because the cost of repairing an old lens is not that much less than manufacturing a new one.

    If the glasses are more than a year old, it makes more sense to have the prescription checked to see if it has changed before you have an old lens repaired. Up to about the age of 25, an individual's eyes are likely to change enough to warrant a new pair of lenses on an annual basis. They tend to change little until middle age arrives, when further changes bring the need for bifocals and regular examinations again.

    Re: "how do I remove the antiglare coating"

    Some coatings chemically bond to plastic lenses. These may be impossible to remove, except through precision polishing, which would likely cause optical changes to the lens. Poorly-bonded coatings can be physically peeled off, but such inferior coatings are rare today. There are specialty chemicals on the market that are used to dissolve some coatings, but these must be selected to match the type of coating and, usually, the type of plastic used to manufacture the lens (e.g., http://www.lenscoloring.com/lenscoloring/htm/Accessories/AR_Stripper.htm). The use of the wrong chemical stripper may ruin a lens.

    • 6/16/06. I agree, this does not fully answer the question. I have the same problem. How can I find more about the 'SPECIALTY CHEMICALS'?
