The Basics: Understanding the Prescription
A glasses prescription is typically written using two mn parameters: Sphere and Cylinder with their corresponding numbers expressed as D or diopters. The Sphere value indicates how much correction is needed for myopia nearsightedness or hyperopia farsightedness, while Cylinder represents astigmatism, which affects the shape of your cornea.
How to Calculate Your Prescription
Sphere Value Calculation: This is calculated based on the difference between what you can see clearly and what your eye actually requires for clear vision at a standard distance, typically measured in meters usually 4 meters. If you are able to read small print without difficulty but struggle with reading large text from far away, it indicates that you need correction.
Cylinder Value Calculation: This comes into play when both eyes don't have perfect spherical curvature and require different prescriptions for optimal vision. Astigmatism affects the eye like a cylinder and needs to be corrected differently than normal spherical lenses.
The Role of Lens Materials
In calculating your glasses prescription, lenses' focal length or optical power plays a critical role. The shorter the focal length in relation to its size, the more curvature it has, which translates into higher optical power and potentially increased weight or thickness.
A negative lens with a short focal length is needed for myopia correction, whereas a positive lens with a longer focal length corrects hyperopia. The prescription calculation guides lens manufacturers on how much curvature to add to the surface of the lens.
