Correction Insert Medi.Glass for Oakley SI URX ESS Black — prescription lens insert

The Medi.Glass correction insert for Oakley SI URX and ESS-compatible frames provides an internal prescription lens solution that fits inside compatible tactical and sports eyewear. Designed in black to match the inner frame aesthetics, this insert allows wearers who need vision correction to use Oakley SI URX or ESS-style goggles without altering the outer lenses. The product is intended for retrofit installation into frames that explicitly support Oakley SI URX / ESS-compatible inserts and is supplied as an internal optical module rather than a full replacement lens.

Advantages

The insert allows prescription optics to be added to compatible Oakley SI URX and ESS eyewear while maintaining the original outer lens and frame functionality. Its black finish is chosen to integrate discreetly with the frame interior. Because it mounts inside the frame, the correction module protects the prescription lens from direct exposure and impact, preserving optical alignment in active use.

Suitable for

• Users of Oakley SI URX or ESS-compatible frames who require prescription correction
• Tactical and shooting activities where corrective optics are needed inside protective eyewear
• Sports and outdoor activities that use compatible eyewear and benefit from internal prescription inserts
• Retrofit installations when the frame supports internal prescription modules

When it may not be suitable

This correction insert is not a standalone replacement lens and cannot be used in frames that do not explicitly support Oakley SI URX / ESS-compatible internal inserts. It is intended for retrofit into compatible frames only; attempting to force-fit into incompatible eyewear may result in poor optical alignment or damage to the frame. Users with complex frame geometries or non-standard mounting systems should verify compatibility before purchase.

Key specifications

• Compatibility: designed for Oakley SI URX and ESS-compatible frames
• Finish: black internal mount
• Type: internal prescription lens insert for retrofit installation
• Intended use: corrective optics for tactical, shooting, sports, and protective eyewear
• Installation: mounts inside the frame behind the outer lens

How to use

Installation typically involves removing the outer lens per the frame manufacturer's instructions, positioning the Medi.Glass insert inside the frame at the prescribed mounting points, and securing it according to the frame's internal retention system. Optical prescription must be ordered and fitted to the insert prior to installation. After installation, verify proper alignment, clear field of view, and that the insert does not interfere with ventilation or anti-fog features of the outer lens.

What to consider before purchase

• Confirm that your frame explicitly supports Oakley SI URX or ESS-compatible internal inserts
• Ensure you have a valid prescription suitable for an internal insert format
• Check whether your frame requires specific mounting hardware or professional fitting
• Be aware that outer lens properties (tint, coating, anti-fog) remain separate from the insert

Usage recommendations

Have the insert fitted by a qualified technician or follow the frame manufacturer's installation guide. Verify optical alignment and ensure the insert does not compromise the frame's protective features. Regularly inspect attachment points and clean the insert with lens-safe solutions to maintain clarity and performance.
