Prescription Limits

Your glasses prescription is made up of several key components, each designed to help you see clearly and comfortably. Whether it’s correcting nearsightedness, farsightedness, or astigmatism, every detail in your prescription plays a role in crafting the perfect lenses for you.

To ensure you get the best possible vision, our labs are equipped to handle a wide range of prescriptions. Here’s a quick overview of the maximum prescription strengths we can accommodate.

Single-Vision Prescription Strengths

Single-vision lenses are the go-to for most people with a simple prescription for either nearsightedness or farsightedness. They provide one power throughout the entire lens, making them ideal for anyone who doesn’t need multifocal glasses.

Sphere: -20.00 to +12.00
Cylinder: ±6.00
Prism: Up to 5.00 in any base direction
Dual PD Difference: 5 mm max

Bifocal Prescription Strengths

For those who need help with both near and distance vision, bifocals are a great choice. These lenses have two distinct parts: one for distance and one for reading.

Sphere: -9.00 to +6.00
Cylinder: ±6.00
Near Vision Add: Up to +3.50
Dual PD Difference: 3 mm max

Progressive Prescription Strengths

Progressive lenses offer a seamless transition between multiple focal points, ideal for people who need help with both distance and close-up vision, but don’t want visible lines like those in bifocals.

Sphere: -10.00 to +8.00
Cylinder: ±6.00
Near Vision Add: Up to +3.50
Dual PD Difference: 3 mm max

Different Factors to Consider

While there are plenty of stylish frames to choose from, your prescription might affect your frame options. When you're shopping for frames, keep an eye out for the "Details" section on the product page. This will tell you the prescription and PD (pupillary distance) range that the frame can handle. It's like a little secret code to help you find the perfect pair for your eyes.

Prescription Range: This indicates the maximum sphere, cylinder, or combination of numbers that a frame can accommodate. If your prescription exceeds this range for either eye, it could be tricky to fit into the frame.
PD Range: The PD range may be limited further if you have different dual PD values for each eye. The maximum dual PD difference is:
- 5 mm for single-vision lenses
- 3 mm for bifocals and progressives
- To determine if your PD fits within a frame: use the smaller of your two PD values and double it. If that number falls within the frame’s PD range, the frame is compatible.
Lens & Frame Limitations: Both lens and frame options may vary depending on your prescription. Keep in mind that the maximum prescription range may differ for certain frame and lens designs.
