The Product

Two Films.
One Complete System.

Most lens damage comes from two sources: abrasion from the outside, and fogging from the inside. Gurkha Optics addresses both — independently, removably, and without compromising your view.

Outer Surface · ClearGuard

Engineered for
the elements.

Watch what happens when rain meets your lens.

Rain hits.
Beads form.

The hydrophobic coating causes water to bead and separate instantly.

Rolls off.
Always clean.

Anti-scratch. Rain-repellent. Smudge-proof. One film.

Inner Surface · AntiFog

Fog doesn't
stand a chance.

Advanced hydrophilic engineering. Instant moisture dispersal.

Without AntiFog,
this is your view.

Temperature changes. Masks. Sweat. Your lenses fog. Your vision fails.

Instant
clarity.

AntiFog disperses moisture before it forms. Always clear.

Origin

Built Here.
For the World.

Gurkha Optics was born in Kathmandu. The cutter in every kit is manufactured in Nepal — a deliberate anchor to local craftsmanship in a product built for global performance.

Bootstrapped from the ground up — no venture capital, no debt. A mechanical engineering student's first product, built with discipline and precision.
Local manufacturing matters. The custom cutter is produced in Nepal, creating domestic supply chain value while keeping quality controlled.
Dhulikhel campus, Kathmandu University — where the product was conceived, engineered, and specified. Mountain clarity, ground-level practicality.

About Gurkha Optics

Clarity Is Not an Accident.

Gurkha Optics is an optical technology startup focused on one problem: the degradation of lens performance over time. Scratches. Fogging. Residue. Each one preventable — if the right protective layer exists.

“Every pair of glasses deserves the same optical clarity on day 1,000 as it had on day one.”

Our two-film system is the first product we're bringing to market — a removable, replaceable protective film set designed specifically for prescription lenses and sunglasses, with optical-grade specifications built in from day one.

We are pre-revenue and bootstrapped, but every parameter in our spec sheet is grounded in materials science and optical engineering. We don't compromise on what matters: what you see through your lenses.
