Astigmatism occurs when the cornea or the lens in your eye has an irregular, oblong shape, which prevents light from hitting a single focal point on your retina. Thus, things look blurry, stretched, or distorted at different distances. Your eye is focusing light at multiple different angles.
This is where the specialized engineering of toric lenses becomes your best friend. Unlike regular contacts, these are crafted with different corrective powers across different parts of the lens to align precisely with your eye's unique curvature.
Proclear toric lenses are designed with a specific stabilization zone that keeps the lens from spinning. This ensures that the corrective zones stay perfectly aligned with your astigmatism, providing that steady, high-definition clarity.
Getting a Prescription for Proclear Toric Lenses
Because astigmatism is all about the unique geometry of your eye, your doctor needs to ensure the lens sits at exactly the right angle to keep your vision sharp. Your prescription needs to account for not just your vision strength, but the specific map of your eye's surface.
Follow these steps to ensure you're getting the most out of your Proclear lenses:
- Book a specialized toric exam. When you schedule your appointment, be sure to specify that you prefer a toric contact lens fitted for astigmatism, as this requires measurements that a standard glasses exam doesn't cover.
- Your doctor will determine two crucial factors, your eye's cylinder and axis. These figures tell the doctor exactly how much correction you need and precisely where that correction should be positioned on your eye.
- Using a keratometer, your doctor will map the corneal curvature of your eye to ensure your Proclear lenses aren't too tight or too loose.
- Ask your eye care professional if the PC Technology in Proclear is the right fit for your lifestyle and comfort needs.
- You'll likely wear a diagnostic pair in the office. Your doctor will watch how the lens rotates and settles after you blink to make sure the stabilization zones are working correctly.
- Expect quick follow-ups. Sometimes a small tweak to the axis or cylinder is all it takes to turn good vision into perfect vision.
- Check the final paperwork. It should include the brand name, sphere, cylinder, axis, base curve, and diameter.
Once you have that finalized prescription in hand, you're all set to order. Refer to those numbers exactly as written. With toric lenses, precision is the secret to that crystal-clear, steady vision.
