Measured RX carrier
Prescription Inserts Built Behind The Safety Lens.
The Shelter insert is a removable prescription carrier that sits behind the safety lens. It is treated as measured equipment, not a fashion optical add-on.
Suitability checklist
Five Details Decide Whether The Insert Is Sensible.
- A valid prescription less than two years old.
- Pupillary distance, measured or confirmed rather than guessed from an old pair.
- Working distance, especially for near tasks, inspection and bench work.
- Lens type, including whether single-vision, occupational bifocal or reviewed varifocal work is being requested.
- Frame fit, because the insert only behaves correctly when the S1 sits in a stable position on the wearer.
Shelter does not provide eye tests, contact lenses or medical advice. If the prescription is unsuitable for safe site use, the workshop will say no rather than glaze around the problem.

Limits and refusals
Some Work Is Turned Down Because The Wearer Has To Use It On Site.
Shelter does not glaze into untested third-party safety frames. The workshop also does not take children’s prescription work, same-day prescription inserts or varifocal insert work where the prescription, working distance or frame position is unsuitable.
No protection claim is made beyond the marked standard of the frame and lens supplied. The insert corrects vision behind the protective lens. It does not turn an untested frame into safety eyewear.
Matthew founded Shelter Eyewear in 2020 after years of replacing scratched site glasses that were uncomfortable or hard to reorder. That history is why insert work is kept measured and narrow. If it cannot be made repeatable, it does not belong in the range.
“If the insert is wrong by two millimetres, the wearer feels it all shift long before the paperwork notices.”
Care and replacement
Replace The Safety Lens Before A Scratch Becomes The View.
- Replace scratched safety lenses rather than asking the wearer to look around the damage.
- Clean the insert with suitable lens cloths and keep it out of abrasive dust when not in use.
- Reorder using wearer name, insert type, S1 frame colour and lens colour if your site keeps issue records.
- Clear replacement lens sets are £14. Smoke or amber replacement lens sets are £18.
