In this particular episode of Ask an Eye Doc, you will learn:
- Two ways to improve your computer vision if your progressive lenses aren’t working
- The difference between a single vision computer lens and a progressive computer lens
This episode will make more sense if you first know what a progressive lens is. Be sure to check out episode 9 first.
Also, check out episode 10 to learn how you could improve your progressive lenses experience.
For you readers out there, here’s the answer in written form:
Does this sound like you?
“I’m sick of these progressive lenses! The distance vision is great, and the reading is good, but I spend 8 hours a day on a computer, and I just cannot find the right spot to look through. By the end of the day my neck is killing me…”
You are not alone! This is a fairly common problem patients of mine have if they do a lot of computer work.
The problem is that of the three general zones of clarity, the computer zone is the smallest, and it can sometimes be difficult to find. Also, if your computer is not a laptop, chances are you’ll have to tilt your head up in order to get the computer zone in the correct position.
If you’re having trouble seeing the computer with your progressive lens, there are two solutions:
If you haven’t already, try upgrading your glasses to a digital progressive lens. You can learn more about that in episode 10 . A progressive lens minimizes the blending zones and widens the zones of clarity, including the computer zone.
This option works well for some people, but depending on where your computer screen sits, you still may need to adjust your head position to see through the computer zone. If that bothers you, you could benefit from option two:
Using a separate pair of glasses designed specifically for the computer is the best way to have comfortable computer vision. There are two ways to design a computer prescription.
The first is called a single vision lens. This is a lens that only has one focal length, which should match the distance between your eye and the computer. It is helpful to let your optometrist know how many inches away your monitor is from your face.
A single vision lens tends to work well for patients who have a mild to moderate reading prescription (usually people between the ages of 40-55).
The second way to design a computer lens is a specialized progressive lens where the computer prescription is at the top of the lens, and the full reading prescription is at the bottom of the lens. With this type of progressive lens, the computer zone is the largest zone of clarity, making it easy to find.
Since the computer zone is at the top of the lens also allows you to keep your head in a natural position so you don’t strain your neck. This option works well for people with a moderate to advanced reading prescription (usually people over the age of 55).
Consult your optometrist
