One key feature of this system is the refractive power of the eyeball, which acts like a natural lens bing light rays as they pass through it. In simpler terms, this means that the eye's ability to focus incoming light onto our sight is its core function.

2. Hyperopia: Contrary to myopia, hyperopia refers to a situation where your eyeball might be shorter than normal or has less curvature at the front surface, leading to a misfocusing of incoming light onto a spot before reaching the retina, causing difficulty in seeing close objects.

These numbers are expressed on the prescription using two key figures-the spherical degree for correction required and the cylindrical degree if needed, which accounts for astigmatism-a situation where your eye doesn’t focus light equally across its entire front surface.
