Polishing The process of polishing can have two purposes - to simply remove AR coatings to achieve a more vintage, raw look. Or in order to remove or reduce scratches in preparation for re-coating.
Duclos Lenses performs most of their polishing in-house to maintain quality control. Shop All Lenses. Shipping, taxes and discounts calculated at checkout. Orders will be processed in USD. Scratches on glasses are a pain. Spoiler alert — the old adage holds true here. What all those tutorials fail to mention is that you're essentially ruining your lenses in the process of removing those scratches, if you can even get the scratch out at all.
These methods take a long, long time, and they still might not prove effective, but hey, the price is right. In theory, the micro-abrasives within the substances, when combined with force, can gently buff out the scratch.
So if you have the patience of a zen master and are OK with lackluster results, you might want to give it a whirl. This method is applicable for lenses with mirror coating, and it does work. Kind of. At least, it works if the scratch only affects the mirrored layer of the lens. But if you stick a dark lens over your eye, the pupils dilate to capture as much light as possible. The active ingredient in glass etching products is hydrofluoric acid, which is highly corrosive.
The factory-applied coating — called Fog Free — eliminates the condensation of moisture on lenses that causes fogging.
So your lenses and vision stay clear when you make the transition from a cold environment to a warm one. It may also keep your lenses from fogging up during sports and other times you are hot and perspiring. Fog Free can be applied to plastic, polycarbonate and other eyeglass lenses, including high-index lenses and Transitions photochromic lenses. The anti-fog coating is applied to the lenses before they are cut to fit into your frame at the optical lab. Ask your optical retailer about pricing and availability.
Another option in anti-fog lens technology is Optifog lenses Essilor. The anti-fogging property of Optifog lenses is activated by applying a drop of Optifog Activator to each side of the lens, then wiping the lens with a microfiber cloth to thoroughly spread the liquid across the entire lens surface.
This treatment keeps the lenses fog-free for up to one week, according to Essilor. Lens fogging is caused by tiny water droplets that form by condensation on the surface of eyeglass lenses when the lenses are significantly cooler than the surrounding air temperature. Optifog works by uniformly spreading these water droplets across the lens surface so they become invisible, Essilor says.

How to Tell if Lenses are Plastic or Glass? Temperature The glass feels colder to the touch, while plastic feels warmer since it is a better insulator. How to Tell if Glasses are Anti-Glare.
Nowadays, there are many types of coatings that can be applied to lenses to improve their optical properties. Here is the step by step process of removing the anti-reflective coating from plastic lenses: With a cotton swab, scoop a little bit of etching cream. Carefully apply it to the whole surface of the lens both front and back. If you get etching cream on the frame of your glasses, wipe it off with the clean side of the q-tip to prevent any damage to the frame.
Let it sit for 5 minutes. With another cotton swab, do a little scrubbing around the surface of the lens both front and back. Wash thoroughly with soap and water. Repeat the whole process if there is any AR coating left. Most modern glasses come with some type of plastic lenses. But if you own an old pair of glasses or, for some reason, went for the option with glass lenses, then use this method. To remove the anti-glare coating from glass lenses, first, you need to soften it.
Most people use isopropyl alcohol alone with mixed results. By adding some salt water to the solution, you will increase its effectiveness. Place your glasses onto a plate and pour out the prepared solution just enough so the lenses are entirely submerged.
Let it sit in the solution for an hour to soften the anti-reflective coating.
