How to Fix Scratches on Polarized Sunglasses

Polarized sunglasses have always been popular among water sports enthusiasts because they reduce horizontally reflected glare from the water. Many people have purchased polarized sunglasses for use in a number of other outdoor activities including golf, skiing, and even driving. The benefits of polarized sunglasses come with a price, however, which is why discovering a scratch is a big deal. Thankfully, if users know which type of lenses they have, fixing scratches on polarized lenses is easy.


Types of Sunglass Lenses

The type of lens makes a huge difference when it comes to maintenance and care regardless of polarization. It is important to know which of the two main lens materials, glass or plastic, is used in the sunglasses lens. Individuals should also note if lenses are actually polarized or not.

Glass vs. Plastic Lenses

While there are many variations within each category, lenses are made from either glass or plastic. Glass, the original lens material, is much more resistant to scratches than plastic; however, it is also heavier and prone to breakage. Plastic lenses consist of any one of a number of different types of plastic materials including CR39, the most common material found in glasses, polycarbonate, and military-grade NXT.

Sun Protection Options

In addition to the different base materials used in a pair of sunglasses, determining whether or not those glasses are polarized is important as well. The table below describes the characteristics of other common types of sun-protective lenses.


Type of Sun Protection


How to Identify

Anti-Reflective Coating

Blue Blockers

Block "blue light"


Gradient Lenses

Darker tint at top grows lighter toward bottom of lens

Mirror-Coated Lenses

Limits amount of light entering the eye

Different colors of "flash coating" applied to the front of the lenses

Polarized Lenses

Blocks glare from horizontal surfaces

Laminated filter applied to the front of the lens


Those who are trying to fix used sunglasses, especially, should review the different types of sun protection available other than polarization. Compare those to the glasses in question before proceeding with a procedure to fix scratches.


How to Fix Scratches on Polarized Lenses by Type

The method used to repair polarized sunglasses depends highly on the type of lens material. After determining if the sunglasses are made of glass or a type of plastic, proceed with the following steps.

Fixing Glass Lenses

One of the major pros of owning glass lenses is their resistance to scratches. As such, most scratched glass lenses contain deep gouges that are hard to repair. Depending on the severity of the scratch, it may be impossible to fix without professional intervention. There is one method, however, that works for minor surface scratches on polarized glass lenses.

  1. Find a tube of white, non-abrasive, non-gel toothpaste and squeeze a pea-sized drop onto a cotton pad.
  2. Rub the toothpaste over the scratch in a gentle, circular motion.
  3. Wipe off the toothpaste using one side of a microfiber cloth.
  4. Using the clean side of the cloth, dampen and wipe the lens until the toothpaste disappears.

Depending on the depth of the scratch, it may be necessary to repeat these steps more than once to produce ideal results.

Fixing Plastic Lenses

Not only are plastic polarized lenses far more popular, they are also easier to repair when scratched. The depth of the scratch may preclude users from actually repairing the lens, but there is a lot more leeway with plastic lenses.

  1. Begin by thoroughly cleaning both lenses with warm water and a bit of mild dish soap, and then dry them completely.
  2. Apply a thin coat of scratch-removing polish or petroleum jelly to the entire lens. Furniture polish, car wax, and non-abrasive white toothpaste work as well.
  3. Use a clean, dry microfiber cloth to rub the polish in gentle, circular motions for 10 seconds.
  4. Inspect the lens, looking to see if the scratch is still visible. If so, repeat.
  5. Repeat the first step to cleanse the lenses.

When fixing the lenses on plastic polarized sunglasses, the basic idea is to fill in the scratch with an oily substance. As such, many similar products work well.


How to Buy Polarized Sunglasses on eBay

Using eBay to buy polarized sunglasses or the materials needed to repair them is an excellent way to save time and money. With many reliable sellers, it is easy to find the perfect pair of new or used polarized sunglasses with a general search from any page on the site. From there, filtering products according to color, brand, or price makes finding the perfect pair simple. Making an investment in polarized sunglasses is a benefit for the eyes and a drawback for the wallet. That is why it is important to know how to fix minor scratches and protect your investment.
