UV - ULTRA VIOLET
MEDIUM IMPACT CERTIFIED
Invisible rays of radiant energy with wavelengths that range between 200-400nm.
UVA and UVB rays are considered harmful to your eyes and skin that can be
generated by solar or artiocial sources.
Eye protectors that are tested and meet the Medium Impact requirements
of AS/NZS 1337.1 are examined and certioed by a third-party independent
certiocation body.
Independent certiocation also provides manufacturers with an individual license
number, which signioes registration and waives an ongoing testing program to
ensure product production delivers a consistently high standard of quality and
performance.
BLUE LIGHT
Has a wavelength of between approximately 380nm-500nm. Although one of the
shortest, its highest energy wavelength can damage the retina, cause eyestrain,
fatigue and headaches. Main sources are sunlight, nuorescent and LED lighting,
digital screens and electronic devices.
IR - INFRA RED
IR rays have a longer wavelength than visible light and are also known as heat
rays. Long term exposure can lead to lens, cornea and retina damage.
Main source - The sun and mechanically generated such as gas welding.
NM - NANOMETER
The unit measure of a light wave. 1 nanometer = 1 billionth of a meter.
UV385 LENSES
Filter out 100% of UV rays up to 385nm and are mainly used in clear lenses.
UV400 LENSES
Filter out 100% of UV rays up to 400nm and are mainly used in tinted lenses.
BASE LENS
Refers to lens curvature and denoted by a numeral preox. Most wraparound
designs would generally have a measured curve of 8 plus.
MEDIUM IMPACT
Eye protectors that are tested to Medium Impact as per the requirements of
AS/NZS 1337.1:2010. This includes subjecting the eye protector to front-on as
well as side impact by using a 6 mm steel ball projected at a speed of 45m/sec
(162km/h). The Medium Impact classiocation is the highest level of protection
that can be given to eye protectors which includes goggles.
SMART VUE (PHOTOCHROMIC LENS TECHNOLOGY)
Photochromic lenses darken to a sunglasses tint when exposed to sunlight or UV
ultraviolet and return to a clear state when indoors, away from the sun9s rays.
CO-MOULDED
The bonding of two or more materials during the manufacturing process
Rx READY
A spectacle frame that can be otted with prescription lenses
PC LENSES
Polycarbonate lenses are lightweight and up to 10 times more impact resistant
than plastic or glass lenses. They also provide up to 99.9% protection from UV
rays and can be further treated with a series of coatings such as anti-scratch
and anti fog
FRAMES
The majority of our range consist of two main types of materials.
1. Polycarbonate - Lightweight and strong
2. Nylon - Durable and nexible
