There are many different types lenses you can get on your glasses. They may be as simple as single vision plastic lens to help you see the range that your eyes aren’t good at, to high tech lenses to help with smaller and more obscure issues.
We’ve compiled a list of some of the more common types of lenses, and how they affect and help your eyesight in different situations.
Here are the 8 types of prescription lenses:
Single Vision Lenses
Helps with one viewing distance, whether it be far or nearsightedness.
Bifocal Lenses
Lenses are split horizontally in the middle, with the top and bottom having different purposes. Usually the bottom half will be for short and close distances, and the top half will be for seeing further away.
Progressive Lenses
These are one of the most popular types of lens, especially for older generations as eyes become weaker into old age. These lenses have three different viewing zones, reading, medium, and long distance.
They progressively go from zone to zone, with no distinct line, and provide the wearer with all necessary zones to not need to switch glasses to read or watch tv throughout the day.
Tints
This is simply a coating on the outside of the lenses, to give it a darker tint or a certain color, as it is usually available in all sorts of brightly colored styles.
Blue Light Lenses
These lenses are specifically made to reduce blue light entering your eyes. Blue light has been shown to do damage to retinas, especially over long periods of time, and contribute to macular degeneration.
The biggest source of blue light are electronic devices such as cellphones and computers. Extended use of devices without some sort of blue light filter can lead to dry and itchy eyes, but with glasses lenses filtering out this kind of light your eyes get a rest from all the strain.
Active Lenses
These lenses are much thinner than regular lenses, but can handle a lot more strain and impact resistance. They also filter 99% of the sun’s UV rays. These lenses are usually used for protective and safety eyeglasses, and for children.
Digitally Surfaced Lenses
THese lenses are made to give the user a wider field of vision and extra clarity. They are put through a process to give every millimetre of the lens crystal clear focus, allowing the user to see through every point of the lens, thus giving a spectacular all around view.
Photochromic Lenses
Photochromic lenses are made to transition from regular prescription lenses to a darker tint, sunglass-like lense. When sunlight hits these lenses, the start to slowly become darker, acting as sunglasses when you go outside.
Although they aren’t as dark as polarized sunglasses, they provide enough of a tint and block UV rays as well as glare. These are a good pick for those who don’t want to wear sunglasses on top of their prescription glasses, and work throughout the day.
