What does it mean if your vision prescription is plus 4.25?

A plus 4.25 vision prescription indicates that you have hyperopia, also known as farsightedness. This means that you can see distant objects clearly, but close objects appear blurry.

The positive sign (+) in your prescription indicates that you need convex lenses to correct your vision. Convex lenses are thicker in the center and thinner at the edges, which helps to focus light on the retina at the back of your eye.

The number 4.25 represents the amount of correction you need in diopters (D). One diopter is the amount of correction needed to focus light on an object that is one meter away. So, a +4.25 prescription means that you need 4.25 diopters of correction to focus light on an object that is one meter away.

It's important to note that your vision prescription is just a starting point. Your optometrist or ophthalmologist will likely fine-tune your prescription during your eye exam to ensure that you have the best possible vision.
