A lens coating is a treatment for glasses that’s added to improve the performance, appearance and durability of your eyewear. There are many different types of coatings, each with its own benefits. While some may be included in the price of your prescription, others are add-ons that will cost you extra. Here’s what you need to know.

Types of Lens Coatings

Here are some of the most popular lens coatings on the market:

  • Scratch-resistant coating: This treatment helps to strengthen and extend the life of your lenses. It creates a hard, durable surface. Typically, this lens coating comes with a warranty.

  • Anti-reflective (AR) coating: This is one of the most popular lens treatments for prescription eyeglasses. They reduce glare and halos and can help to decrease eye strain. They also create a more flattering appearance by reducing surface reflections.

  • Anti-glare coating: This treatment reduces the amount of light that bounces off your glasses. It’s a great option if you work with computers or if you drive at night.

  • Ultraviolet (UV) protection: This lens option shields your eyes against harmful UV rays, which can help prevent the development of cataracts and macular degeneration. When purchasing sunglasses, make sure your lenses provide 100 percent UVA and UVB protection.

  • Mirror coating: This treatment helps to reflect light, reducing the amount that makes it through the lenses of your glasses and into your eyes. They’re also a great feature for adding style and personality.

  • Digital coatings: This lens option helps block the harmful blue light wavelengths that are emitted by devices like cell phones, computers and tablets. Blue light may contribute to eye strain and disrupted sleep.

  • Photochromic or transition lenses: These lenses have a light-adjusting technology that causes your lenses to get darker when they’re exposed to UV rays and clearer in dim settings. Transition lenses help provide consistent protection for your eyes.

  • Polarized lenses: These lenses have a filter that blocks horizontal light waves to minimize glare and reduce brightness.

  • Anti-fog coatings: This treatment helps prevent your lenses from fogging up in hot and humid conditions. They’re often added to sports goggles and glasses with a tight seal. They’re also a great option to help combat mask fog.
