Have you ever seen a term like “cylinder” or the abbreviation “CYL” on your prescription? Don't worry, this is quite normal. A cylinder on your prescription means that you have a so-called cylinder defect, or astigmatism. This is very common and simply means that your eye is not completely round but has more of an oval shape. As a result, you need a cylindrical correction in your glasses, which is indicated on your prescription by a number next to the cylinder abbreviation.
If you need prescription safety glasses for work, it is important that these glasses also correct your cylinder deviation. In this blog, we explain why this is essential and how you can get the right safety glasses that offer both protection and optimal vision.
A cylinder defect (astigmatism) means that the cornea or lens of your eye is not perfectly round. This causes light rays to be refracted in a different way, causing you to see blurry or distorted. A pair of glasses with cylindrical correction ensures that this deviation is corrected, so that you can see clearly again.
Do you have a cylinder on your prescription? Then you see a number with the abbreviation C whether CYL, which indicates the strength of the correction. Just like normal strength, the cylinder value for your left and right eyes may differ. If there is no cylinder in your prescription, you do not need a cylindrical correction.

Safety glasses should not only protect your eyes, but also optimally correct your vision. People with a cylinder anomaly often have more trouble seeing clearly without proper correction. In a work environment where you depend on good vision — for example in construction, the chemical industry or laboratories — blurred vision can be dangerous. Safety glasses without cylinder correction can lead to a number of problems:
For people with astigmatism, it is important that their safety glasses are specially tailored with the correct cylinder correction. Here are a few points to pay attention to:
If you have a cylinder defect, it is important to choose safety glasses that not only protect your eyes, but also optimally correct your vision. Glasses without the correct cylinder correction can lead to fatigue, headaches and an increased safety risk in the workplace. Make sure your prescription goggles are fully tailored to your specific needs, including correction for astigmatism.
