If you're having trouble reading the text on your screen or distinguishing signs on the road, then perhaps you could use some assistance from single vision lenses. What are single vision lenses?In a nutshell, single vision lenses are a type of lens that provides optical correction for a single distance. There are several kinds of single vision lenses that you can use, depending on the eye concern that you have. What refractive errors can single vision lenses correct?To better understand how single vision lenses work, it's helpful to understand the different types of refractive errors out there. They can be something that a person is born with or something that develops as they age.
By manipulating the way light enters the eye, single vision lenses allow light to properly focus on the retina, helping those with refractive errors achieve the crystal-clear vision. Single vision lenses vs other types of lensesMuch like its name suggests, single vision lenses are catered for individuals who need correction mainly at one distance.

The different types of single vision lensesSingle vision lenses come in many different forms and materials. Here are 3 common types: 1. PolycarbonatePolycarbonate lenses are durable and impact resistant and are more lightweight and scratch resistant compared to plastic lenses. They are an ideal option for children's glasses or for those who engage in sports, as well as individuals who are always out and about, since polycarbonate lenses also offer UV protection from the sun. 2. TrivexTrivex lenses are a bit thicker than polycarbonate lenses, but are more lightweight and produce sharper peripheral vision compared to polycarbonate lenses. Both polycarbonate and trivex lenses offer similar impact resistance and UV protection, though trivex lenses are a bit less accessible compared to the former. 3. High indexThese lenses are usually recommended to people with high prescriptions, as high index lenses are made from special material to keep them light. This is a great alternative to regular plastic lenses, which usually need to be much thicker to accommodate strong prescriptions. High index lenses present a slimmer, and more lightweight alternative. Frequently asked questions1. What are single vision lenses used for?Single vision lenses are used to help people with farsightedness, nearsightedness, or astigmatism see clearer. This type of lens contains one correction that is distributed evenly across the entire lens' surface area, which will allow light to properly focus on the retina. 2. What is the difference between single vision and reading glasses?Reading glasses are a type of single vision lens that many farsighted wearers use to help them see close-up images or texts better. Those who need the same correction for both eyes usually purchase reading glasses over the counter, however, those who require different corrections per eye will have to get a prescription from a doctor. 3. Can you wear single vision glasses all the time?Of course! There is no reason why you can't wear your single vision glasses throughout the day, but some people prefer to only use them when they need to (e.g. when driving, watching a movie, playing sports, etc.) 4. Do single vision lenses correct astigmatism?Yes. Since those with astigmatism have an irregularly shaped cornea, single vision glasses for astigmatism will include special cylindrical lenses to make up for how light passes through the cornea's asymmetric curvature, producing a sharper picture once worn. |
