If you’ve ever had to purchase eyeglasses, you know finding the right pair isn’t easy. With so many frame styles and colors to choose from, it can be overwhelming. And if that’s not enough, you also have to consider what type of lens and coating you want as well. But don’t worry! In this blog, we’ll explore the different types of eyeglass lenses and lens coatings to help you decide on the right ones for your needs.
Types of eyeglass lenses
There are many types of eyeglass lenses available. Here’s a look at the most common options:
1. Single vision lenses
This lens is great for people who only need one vision prescription, either for distance or reading. Single vision lenses are usually the most affordable option, but they only correct vision for one distance. If you need correction for both near and distance vision, bifocals or progressives are a better choice.
2. Bifocal lenses
Bifocal lenses are perfect for those who need glasses to see both up close and far away. They have two zones of vision divided by a visible line. The top part is for seeing objects far away, and the bottom part is for near tasks like reading. Bifocals are a great option if you need correction for both near and far distances, but don’t want to switch between two pairs of glasses.
3. Progressive lenses
Progressive lenses, also known as no-line bifocals, offer a smooth transition from distance vision at the top of the lens to reading vision at the bottom. You can see clearly at varying distances without the noticeable line on the lens like bifocals.
Progressive glasses are perfect for those who need vision correction for multiple vision problems. For instance, if you are nearsighted and later develop presbyopia (age-related difficulty seeing up close), they may be right for you. However, progressive lenses can be more expensive than single vision lenses and may take some time to adjust to.
4. Photochromic lenses
Photochromic lenses are lenses that darken when you’re outside in the sun and become clear again indoors. They are ideal for people who spend a lot of time outdoors or are sensitive to light. You can get photochromic lenses in both single vision and progressive options, so they’re a great choice if you want both vision correction and sun protection.
5. High-index lenses
High-index lenses are a good option for people with strong prescriptions who want lighter, thinner glasses. They are thinner and lighter than standard lenses for high prescriptions, making them more comfortable to wear. They are also suitable for people with high astigmatism, reducing the distortion often seen with standard lenses.
6. Polycarbonate lenses
Polycarbonate lenses are a great option for people who are looking for a lightweight and durable lens. These lenses are made from a highly impact-resistant material that is perfect for kids, athletes, and anyone who is prone to accidents.
Polycarbonate lenses provide excellent UV protection, making them ideal for people who spend a lot of time outdoors. These lenses are also known for their scratch resistance, which helps prevent scratches and dings over time.
Lens coatings and treatments
Along with different types of lenses, you can also choose from many different types of coatings. Here are some of the popular ones:
- Anti-reflective coating: This lens coating reduces glare and reflections to improve visual clarity and comfort. It can help lessen eye strain when using digital screens, reading under artificial lighting, or driving at night.
- Scratch-resistant coating: A scratch-resistant coating is a great choice if you want extra protection for your glasses, especially if you’re always on the go or working somewhere where your lenses could get damaged.
- UV-blocking treatment: This coating helps protect your eyes from harmful UV rays, which can damage your eyes and increase your risk of cataracts and macular degeneration later in life.
- Blue light-blocking treatment: This lens treatment helps to block or filter out blue light coming from digital screens, protecting you from digital eye strain and fatigue.
