In this video, you'll learn how to distinguish between common astigmatism and a condition that can go unnoticed for years and gradually deteriorate vision.

Very often, people notice their vision is deteriorating, try glasses, and see better for a while, but then again experience blurriness, distortion, and the need to change their prescription. At this point, it may seem like the problem is simply progressive astigmatism or myopia.

But in some cases, keratoconus may be the underlying cause. I'll explain in detail why this happens, what changes occur inside the eye, and what signs to look out for if glasses or lenses no longer provide the same clarity. You'll understand when the situation goes beyond common astigmatism and requires a more in-depth examination.
