High Prescription Safety Glasses

This section is designed for individuals with high prescriptions requiring ANSI Z87+ safety-rated eyewear. You’re on the correct page if your prescription is above +5.00 or below -6.00 in sphere power or your script has a cylinder value over +/-4.00. RX-Safety has gone through its extensive line of prescription safety frames to identify the best models for high prescriptions, helping you find the most appropriate and functional pair of glasses for your needs. Each frame listed here has been reviewed and selected based on its ability to accommodate stronger prescription lenses while maintaining ANSI Z87.1 safety standards.

Considerations for High Prescription Safety Glasses

1. Frame Design and Shape Matter

RX-Safety has selected frames with flatter curves and smaller eye sizes that are better suited for supporting thicker lenses without compromising structural integrity or optical clarity. We tend to choose more round, oval, or square frame styles because the further you get from the center point of the lens, the thicker and heavier the lens becomes. Smaller and more symmetrical shapes reduce the amount of lens material needed, which helps minimize edge thickness, cut down weight, and improve overall appearance. These frame designs also help maintain better optical performance, especially in progressive lens designs.

2. Wraparound Styles Are Limited

Wraparound safety glasses are popular for their coverage and protection but are usually unsuitable for high prescriptions. The curved design introduces significant peripheral distortion and often can’t physically hold thick lenses. While a few wraparound styles have been designed to support stronger prescriptions, they are the exception rather than the rule, and even then, they usually can’t handle anything with a combined power of +5 or -6 unless they have inserts.

3. Selecting Lens Materials

Lens material is critical to high-prescription safety glasses’ comfort and optical performance. Polycarbonate with a 1.60 index is a common choice due to its impact resistance and relatively thin profile, making it a strong baseline material for safety applications. High-index plastics such as 1.67 and 1.74 are often preferred for higher prescriptions because they significantly reduce lens thickness and weight while maintaining optical clarity and meeting ANSI Z87.1 safety standards. Selecting the right lens material helps ensure your glasses are protective, comfortable, and visually effective throughout the day.

Rx-Safety has created this category to highlight safety glasses that work best with high prescriptions, making it convenient for our customers with higher prescriptions a simple way to find the best pair of safety glasses. Whether in a manufacturing setting, laboratory, or workshop, selecting the right frame is as important as choosing the right lens material.
