When you visit your optometrist to fill a new prescription, chances are that you’re going to spend a lot of time looking at new frames. After all, the frames of your glasses are the most outwardly noticeable components of your eyewear. It’s equally important, however, to consider the different types of lenses while searching for new glasses.
You might think that eyeglass lenses are fairly simple—the optometrist will shave them down to meet the needs of your prescription, and then they’ll fit them into the frames. In reality, there are several different types of eyeglass lenses in Cape Cod, MA. It’s important to understand the differences between these distinct lens types in Cape Cod, MA so that you’re investing in eyewear that meets your unique medical needs.
Lens Construction Materials
There are several common construction materials that are used to build eyeglass lenses. Here are just some of the most common lens materials and their respective benefits:
- Glass: In the olden days, all lenses were made from glass. While glass does offer some of the best possible clarity, it’s also heavy and breaks easily. Today, there are lighter, more affordable options compared to glass lenses that are more commonly used.
- Plastic: Lightweight and affordable, plastic is among the most common type of material used to build eyeglass lenses today. Unfortunately, plastic is easily scratched. Additionally, it isn’t very easy to see out of plastic lenses. Plastic lenses are also often very thick.
- Polycarbonate: Developed as a form of “bulletproof glass,” polycarbonate is actually a plastic resin that offers many of the benefits of glass eyewear combined with the perks of plastic.
- High-index plastic: High-index plastic lenses are lighter and thinner than traditional plastic lenses, making them a much more stylish choice when polycarbonate lenses aren’t an option.
Lens Coating Types
In addition to the materials used to build the lenses themselves, lenses are often treated with coatings that keep them in good shape, or perform special functions. Here are just some of the lens coating types to be aware of:
- Anti-scratch coating: If you’re investing in lenses made of a lighter, softer material, like plastic or high-index plastic, you should plan to invest in an anti-scratch coating, which will make your lenses more scratch-resistant.
- Anti-reflective coating: Anti-reflective coatings are an extremely important addition to include in your next eyewear order. These coatings prevent glares and reflections, which can be distracting. Additionally, the coating reduces contrast and improves clarity.
- UV-treatment: This coating is fairly straightforward—it simply blocks out the ultraviolet rays, which could cause degradation of your eyesight over time, and even lead to the development of radiation-related eye concerns.
