For many people who wear glasses, anti-reflex coating is a good choice. Spectacles treated with anti-reflex coating reflect less light, which eliminates much of the glare associated with wearing glasses. Anti-reflex coating can also make it easier for wearers to drive at night, since less light from oncoming headlights is reflected in the glasses. Even so, anti-reflex coatings are not right for everyone, and it's important for spectacle shoppers to consider the pros and cons carefully. In addition to the advantages, buyers should be aware of several disadvantages.
One of the biggest disadvantages of adding anti-reflex coating to eyeglasses is the high cost. Depending on the type of lens and the nature of the prescription, anti-reflex coating can add significantly to the price of the finished spectacles. Shoppers considering the anti-reflex option should ask for a quote that details the basic cost of the eyeglasses and the price of each option. This will make it easier to decide which add-ons are essential and which are not.
Hard to Clean
Many eyeglass wearers find that lenses treated with anti-reflex coatings are harder to keep clean than those that have not been treated. The anti-reflex coating seems to attract dust and grime, which requires more frequent cleaning. It's also important to use the right cleaning materials on spectacles that have been treated with anti-reflex coating. Specially designed eyeglass cleaning pads work best, and tissues or cloths could damage the anti-reflex coating and scratch the glasses.
Another potential problem posed by anti-reflex coating is the additional weight it adds to the glasses. If a prescription is lightweight and uncomplicated, this issue won't be a concern, but if a prescription is heavy, the additional weight from the anti-reflex coating could make the spectacles uncomfortable to wear all day. For this reason, many shoppers use lightweight polycarbonate lenses when adding anti-reflex coating, but even these lenses can be a little heavy. Polycarbonate lenses also tend to be a bit pricey, so shoppers need to consider the benefits of anti-reflex coating against the added cost as well as the added weight.
