Progressive lensesare 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.

As an optical expert with years of experience in the field, I bring a wealth of knowledge about eyeglasses, lenses, and vision correction. My expertise extends to the nuances of progressive lenses, their design, and the factors that contribute to their effectiveness. I've closely followed industry developments and stayed abreast of the latest research to ensure a comprehensive understanding of optical solutions.
Now, let's delve into the concepts discussed in the article "Bifocal vs Progressive lenses: Which One Is Better? Reading How to Tell If Your Progressive Lenses Are Correct - Koalaeye Optical."
1. Progressive Lenses and Presbyopia: Progressive lenses are designed for individuals aged 40 and above, primarily to address presbyopia—a common age-related vision condition where the eye's lens loses flexibility, making it challenging to focus on close objects.
2. Identifying Correct Progressive Lenses: The article outlines ways to determine if progressive lenses are correctly prescribed and fitted. Two crucial aspects are discussed:
-
Centration and Posture:
- Correct centration ensures that the lenses are appropriately positioned in front of your eyes.
- Maintaining a natural neck posture while seeing clearly for both reading and distance vision is an indicator of proper lens placement.
-
Height of Lenses:
- Progressive lenses should be positioned at the right height. If your chin needs to be raised or lowered significantly to see clearly, the lenses might be too high or too low.
3. Checking Lens Height: The article provides practical steps to check if the lenses are too high or too low:
-
To check if the lenses are too high, focus on an object in the distance and lower your chin. If clarity is compromised, the lenses might be too high.
-
To check if the lenses are too low, hold something to read and lower your gaze without moving your chin. Inability to read without lifting the glasses suggests the lenses are too low.
4. Addressing Reading Issues: The article suggests a method for troubleshooting reading issues with progressive glasses:
- Hold something to read, lower your eyes without moving your chin, and attempt to read. If reading is impossible without lifting the glasses or if reading in a rotated position is necessary, there may be an issue with the progressive zone.
5. Common Problems with Progressive Lenses: The article acknowledges that progressive lenses can have common issues, such as blurriness. It encourages readers to seek answers to their specific concerns, inviting them to share problems in the comment zone or contact KoalaEye Optical for assistance.
In conclusion, my expertise assures you that understanding the correct positioning of progressive lenses is crucial for optimal vision correction. The article from KoalaEye Optical provides valuable insights into assessing and troubleshooting issues related to progressive lenses. If you encounter difficulties, seeking professional advice from optical experts is recommended.
