Single-Vision Glasses
While searching for your next pair of eyeglasses online, you might come across several terms to describe eyeglass lenses like “single vision,” “bifocal,” “progressive,” or “multifocal.” But now you're probably wondering what single vision glasses are.
Single vision eyeglasses are the most popular type of prescription lenses and correct for one field of vision. Single vision glasses are commonly used for nearsighted or farsighted users and those with astigmatism to help see at a distance of up to 30 feet. They can also be used for other common daily activities like reading, looking at a computer screen or driving.
Features of Single-Vision Distance Glasses
A benefit of wearing single vision glasses is the variety of options you can choose from for your lenses. When selecting your frames and lenses, it's important to consider what will best suit your day-to-day wear, like the material of the lenses, the designs, and the coatings.
Three popular eyeglass lens materials include plastic, polycarbonate, and high-index plastic. Plastic lenses are desirable for many eyeglasses because it is lightweight, has excellent optics, and is inexpensive.
Polycarbonate lenses are lightweight and the most durable of the three lens materials. They're ideal for children or for those who play sports because they are very difficult to shatter.
Finally, high-index plastic lenses are also thin and lightweight and block 100 percent of UV rays.
Once you've established which lens material is the most beneficial for your frames, you can decide on a lens coating so you've got the most comfortable, durable, and stylish eyeglasses possible. Common eyeglass coatings include anti-scratch, anti-reflective, UV-blocking treatment, and photochromic treatment.
All lightweight lens materials are softer than traditional glass and are more susceptible to scratches. Most scratch-resistant coatings will make your lenses as tough as glass. Anti-reflective coatings are ideal because they make your lenses practically invisible, reduce the number of reflections you see through your lenses, and eliminate contrast and clarity issues you can have at night.
UV-blocking and photochromic treatment lenses deal with light and the sun. A UV-blocking coating needs to be applied if you choose a material like plastic. Polycarbonate and high-index plastic lenses have UV protection built in. You'll need that extra boost to protect your eyes against UV damage.
Photochromic treatment coatings allow your lenses to darken in response to light or UV detection and are clear when indoors.
