When it comes to ordering your next pair of glasses, whether from David Kind or another brand, one of the most important steps is making sure your prescription is up-to-date. Understanding your eyeglass prescription on your own can give you a better sense of how your vision has changed over time. At first glance, your prescription might seem confusing, but learning how to read it can be incredibly helpful. In this guide, we’ll walk you through how to interpret your eyeglass prescription and highlight the key details you should focus on.
Nearsighted (Myopia)
Nearsightedness, also known as myopia, is a common vision condition where close objects are clear, but distant ones appear blurry. If you're nearsighted, your prescription will show a number with a minus sign in the sphere column. This number represents the lens power needed to correct your vision, measured in diopters.
Farsighted (Hyperopia)
Farsightedness, or hyperopia, is when nearby objects look blurry, but faraway objects are clearer. If you’re farsighted, your prescription will have a plus sign in the sphere section. This value tells you how much correction is needed for near vision.
Astigmatism
Astigmatism is a condition that occurs when the cornea or lens isn’t perfectly round, leading to blurred or distorted vision. If you have astigmatism, your prescription will include two numbers: one in the cylinder column and another in the axis column. The cylinder value measures the degree of astigmatism, while the axis indicates its orientation.
Bifocal & Progressive Lenses
If your prescription includes a multifocal option, you'll see an "ADD" value. These prescriptions are typically recommended starting in your 40s, though exceptions do exist. Bifocals have a visible line and correct for both distance and reading vision. Progressive lenses offer a more natural transition between different focal points—distance, intermediate, and near—all in one lens.
Now that you understand the basics, you might be wondering how often you should get an eye exam. It's generally recommended to have a comprehensive eye exam every one to two years. However, if you start noticing changes in your vision—like squinting, headaches, or difficulty focusing—it’s a good idea to schedule an appointment sooner. These signs can indicate that your prescription may need updating.
