Progressive lenses are popular among people who are over 40 and they can be used to correct presbyopia. If you have a pair of progressive lenses, how can you tell if the progressive lenses are correct or not? If you do not know, you come to the right place. This post will show you how to tell if your progressive lenses are correct.
How to Tell If Your Progressive Lenses Are Correct?
How do I know If I have progressive lenses? There are two parts of the lens you can check. The first is how the lens sits in front of your eyes. If you are not able to see in the distance, either centration is way off the lenses are too high or the lens power is not correct. However, when checking the lens sitting in front of your eyes, you should be able to maintain a natural posture in your neck and see sharp when reading or while focusing on the distance. If you raise your chin high while reading or hold it low to see in the distance, it is not correct.
Now, we will show you how to see if the lenses are too high.
- Look at an object in a distance 65 feet away or more.
- If you can’t see it clear, keep your eyes on the object and lower your chin. Check whether you can see clearly while looking through a more upper part in the lens than your lenses are too high.
Then you need to watch the difference in the blurriness on the contours of the roadsign.
Now, we will show you how to check if your lenses are too low. Hold something you want to read in your hands and lower your look with your eyes. Do not move your chin down as you look down. If you can’t read without lifting the glasses, the lenses are too low.
When you can’t read with your progressive glasses, you can try this way. Hold something you want to read in your hands and lower your look with your eyes. But please note do not move your chin down as you look down. Then look down at something to read but do not lower your chin. Look at something you want to read. Rotate your head to the left and right and right with one eye at a time. If you can read in a rotated position, the reading zone is out of place. If you can’t read at all, the progressive glasses may be wrong.
