In addition to basic vision correction measurements like SPH (sphere), CYL (cylinder) and axis for astigmatism correction, contact lens prescriptions include:

Base curve: A measurement that shows how curved your eye is, specifically, the front surface of your eye, called the cornea. Contact lenses need to match this shape to fit properly. If the base curve is too flat or too steep for your eye, the lens might feel uncomfortable or not stay in place well. So, the base curve helps make sure your lenses sit snugly and comfortably on your eye.

Diameter: This refers to the size of the contact lens, measured in millimetres. It tells us how wide the lens needs to be to properly cover your cornea (the clear front part of your eye). The right diameter helps ensure the lens stays centered and feels comfortable throughout the day.

Lens material and brand: Contact lenses are made from different materials, and some are better suited for people with sensitive eyes or conditions like dry eyes. The brand and material can make a big difference in comfort, eye health, and how well the lens works for you.

Lens type: There are different types of lenses depending on your vision needs
- Single-vision lenses correct general near- or farsightedness.
- Toric lenses are designed for people with astigmatism.
- Multifocal contact lenses help if you have presbyopia, a condition that makes it harder to see things up close as you age. These lenses allow you to see clearly at different near, far, and in between distances.

All of these factors are essential for ensuring your contacts prescription suits your eyes and supports good eye health.
