Have you ever wondered just how many different types of prescription glasses there are and what exactly each type is used for? You may know of someone who uses prescription Eyeglasses, and you may even have a pair from your optometrist, so it would be good to know how your prescription glasses are helping you.
Single Vision Glasses
If you are nearsighted or farsighted, and you are under the age of 40, you will probably be prescribed with single vision glasses. These are the most common lenses that give you clearer, comfortable vision on all parts of the lens. These glasses can also help people who struggle with reading.
Accommodative Support Lenses:
These are the fastest-growing lenses around the world currently, simply because of the increasing need. They are commonly used in people between 10 and 45 years old. Due to the ever-increasing amount of time spent on phones, computers and tablets, more and more people are experiencing strain when reading. These lenses lessen strain and fatigue, giving you more comfortable vision.
If you fall in this age category, do yourself a favour and ask your optometrist to check if these lenses will benefit you after your next eye exam.
This type of lens allows you to have different points of focus in one pair of glasses, so it’s ideal for people who need assistance with seeing both long and short distances. Multifocal lenses are also called progressive lenses, and they are mostly needed by patients over the age of 40.
Your optometrist may prescribe you a progressive lens if you have trouble with multi-distance vision. Before this technology, people would have to swap from one pair of glasses to another. However, the latest technology in progressive prescription glasses eliminates the line across the lens, allowing clear vision without a change in the image.
Furthermore, due to fabulous technology there are premium multifocals that vary in levels of comfort. These lenses have less distortion on the sides, are remarkably more easy to adapt to, and cater to your daily various tasks needs. At Twenty 20 Vision we love premium multifocals because of the pristine vision they offer our patients.

In most bifocal glasses, the bottom half of the lens allows you to read at a close distance, while the top half allows better long-distance vision. Hence with this type, there are two main focal points. These lenses have a distinct line below your lower lid. Bifocal lenses are less commonly used these days because the limitation is that they do not help you see clearly in the intermediate range, like computers, tablets, or newspapers.
These lenses work in the same way as bifocal lenses, except that there is an added middle area which allows you to see comfortably at a mid-range. They are very rarely used these days and are currently being discontinued due to the discomfort of the lens.
Blue Light Protection
Blue light protection is a new type of anti-glare lens enhancement. It’s essentially a coating that protects the eyes from harsh blue light when looking at digital screens. This is particularly beneficial for people who spend on computers, TV, mobile phones, tablets or any other digital devices. A pair of prescription glasses enhanced with this protective layer may be recommended by your eye doctor. It can reduce eye fatigue and also improve the durability of your glasses.
Other Anti-Glare Coatings
There are many types of anti-glare coatings, from generic to premium. Your optometrist will recommend the best anti-glare for you, depending on your day to day activities.
Some people, unfortunately, have very high prescriptions. These lenses can be very thick, with poor optics and they are cosmetically unappealing. Your lenses can be made thinner with compressed lenses ranging from thinner to the thinnest, depending on your preference.
You can have fixed tints or gradient tints added to your glasses. These glasses serve as sunglasses and the tint remains constant. There are also changeable tints that get dark when you’re in the sun and lighter when you are indoors. The generic, cheaper version of these tints is called photochromic lenses. The premium lenses in this category are called Transitions. They are the best because they change from dark to light and vice versa very quickly. Additionally, they get very dark and very light.
