When the cornea or the lens inside your eye has an uneven curve, it causes light to bend unevenly instead of focusing on one clear point on your retina. This condition is called astigmatism. Astigmatism can make vision look blurry, stretched, or distorted at near and far distances. Some people may experience eye strain, excessive squinting, or trouble seeing clearly at night.
SofLens Toric lenses are specifically designed to address this uneven focus by using precision optics that gather light into a much sharper focal point. Because astigmatism correction depends entirely on the lens staying in the correct position, their Lo-Torque design ensures the lens remains stable and properly aligned.
How To Read Your SofLens Toric Prescription
When you look at your prescription for your SofLens contact lenses for astigmatism, you may notice mysterious numbers alongside some specific terms. What do these figures and words mean?
Here is a quick guide to help you understand those specific terms:
- OD and OS: These are shorthand for your right eye (OD) and left eye (OS). It is important to check both, as each eye often requires a different level of correction.
- Sphere: This number indicates the power needed for nearsightedness (marked with a minus sign) or farsightedness (marked with a plus sign).
- Cylinder: This value represents the amount of astigmatism correction you need. Note that toric lenses differ from standard spherical contacts.
- Axis: Think of this as the compass for your lens. It tells the correction exactly where to sit. Because SofLens Toric lenses rely on precise alignment, this number is critical.
- Base Curve: This measurement defines the curvature of the lens. It ensures the contact fits the unique shape of your eye precisely.
- Diameter: This refers to the width of the lens.
- Lens Name: Confirm that your prescription specifically lists SofLens Toric before you finalize your order.
Expiration Date: Like any medical prescription, contact lenses expire. Always verify that your prescription is current. If it has lapsed, you'll need a quick update from your eye doctor before purchasing new lenses.
