SPORT STYLE – 4000 Frameless, Drop Down Lenses, Adjustable Nose Piece Sport 4000 – Clear

R43,41

Lightweight: Frameless style plus minimal hardware should reduce weight, which helps for long wear (sports, cycling, running, etc.).
Secure Fit: Adjustable nose piece helps prevent slipping down the nose; arms/temples likely have non‑slip tips or rubber grips.
Ventilation: With frameless design, often better airflow so less fogging; may have vents or spacing at edges to allow air circulation.

UV Protection: Likely UV400 – blocks almost all UVA and UVB rays.
Impact Resistance: If for sports, lens should comply with some impact/resistance standard (depending on manufacturer; could be ANSI or EN or equivalent). Polycarbonate generally helps with impact.
Glare / Light Control: Possibly drop‑down lenses are tinted/mirrored to reduce glare; maybe photochromic (self‑darkening) in some models.

Feature	Description
Design Style	Frameless (“shield”) front – the lenses are not enclosed by a full rigid frame, giving a wide, unobstructed field of vision. Sleek, sporty look with minimal visual barriers.
Lenses: Drop‑Down	The lenses are of the drop‑down type: you can flip / drop them down over the eyes when needed (e.g. for sun/glare protection) and flip up (or retract) when not needed. Might be hinge‑based or sliding mechanism.
Adjustable Nose Piece	Nose pad / bridge that can be adjusted for fit: either different settings, flexible arms, or movable pad pieces so the glasses sit comfortably and securely on a variety of nose shapes. Likely soft or rubberized material to reduce slippage and pressure.

Lens Material: Usually polycarbonate (PC) or other impact‑resistant plastic. Polycarbonate is lighter, shatterproof, and gives UV protection.
Finish / Coating: Anti‑scratch on the exterior; possibly anti‑fog inside; UV400 filtering to block UVA & UVB rays. Maybe mirrored or tinted options for different light conditions.
Frame Structure: Since “frameless,” only the arms / temples and nose bridge pieces are framed; lens edges exposed. These parts are generally lightweight plastic or polymer; hinges should be durable.
