Frequently Asked Questions

Q: How does the 9-level ND filter work on these adjustable dimming sunglasses?

A: The ND2-400 adjustable filter works by rotating the outer lens element relative to the inner one, progressively stacking the neutral density layers. This lets you select from 9 distinct dimming levels — from a very light tint (ND2) to an extremely dark shade (ND400) — so you can fine-tune light transmission based on how bright your surroundings are, all without changing glasses.

Q: Are these sunglasses suitable for driving?

A: Yes! The UV400-rated lenses and glare-reducing mirror coating make these sunglasses excellent for driving in bright, sunny conditions. The adjustable ND filter lets you adapt quickly as light conditions change — for example, when moving from shaded streets to open highways.

Q: Do the KLASSNUM ND2-400 sunglasses come with a protective case?

A: Yes, each pair includes a protective glasses case to keep your lenses safe from scratches and dust when stored or carried.

Q: What frame and lens materials are used in these sunglasses?

A: The frame is made from a combination of PC (polycarbonate) plastic and metal for a lightweight yet durable structure. The lenses are also polycarbonate (PC), which is impact-resistant and suitable for active outdoor use.
