BLOC CATEGORY 2
HDL HIGH DEFINITION LENS A high definition lens ideally suited for medium to bright light conditions. The light vermilion/violet tint helps with contrast against blue and green. It offers excellent definition in low light conditions with acceptable protection when bright. Ideal for sports played on grass, particularly golf.		BG24 - BROWN GRADUATED The BG24 is similar to the BG12, but has a lighter tint and falls into the Cat 2 range. Definitely more of a fashion lens rather than sport.
SG24 - SMOKE GRADUATED The SG24 is similar to the SG12, but has a lighter tint and falls into the Cat 2 range. Definitely more of a fashion lens rather than sport.
BLOC CATEGORY 3
B11 BROWN BLOC's brown lenses are excellent at reducing glare, working very effectively in varying light conditions and help to reduce eyestrain.		VE5 VERMILION The unique hue of this lens makes it a true all rounder, at home in the brightest conditions, whether on mountain, street or beach. The grey content ensures natural colour transmission and the vermilion enhances red, green and yellow, whilst eliminating a high degree of blue light. This increases perception of detail and dramatically reduces eye fatigue.
DRIVING - VERMILION This lens is soft on the eye, reduces glare and retains natural colour balance. The lens also enhances definition in low light conditions and reduces eye fatigue.		S11 SMOKE This lens transmits the full colour spectrum. It does not change the way colours are seen and is ideally suited for prolonged wearing in bright conditions and for people who have intolerance to colour transformation.
S15 SMOKE Similar to S11, this lens transmits the full colour spectrum. It does not change the way colours are seen and is ideally suited for prolonged wearing in bright conditions and for people who have intolerance to colour transformation.		G15 GREEN This green tint is truly the best all purpose lens, dramatically reducing eye fatigue in bright conditions and offering enhanced definition in lower light.
RED MIRROR This lens is heavily tinted on a grey base for bright to extremely bright light conditions.		BLUE MIRROR This lens is heavily tinted on a grey base for bright to extremely bright light conditions.
POLARISED - S11 SMOKE BLOC’s advanced polarised lenses virtually eliminates uncomfortable glare from reflective surfaces, the ultimate lens for driving, cycling, winter and water pursuits.		POLARISED - BLUE MIRROR This lens is as the Polarised S11 with slightly darker tint and blue mirror coating.
SG12- SMOKE GRADUATED This lens is a smoke grey graduated lens, darker at the top and almost clear at the bottom. Commonly thought of as a fashion lens, but still offers good protection in the Cat 3 range. Not really suitable for snow or water sports.		BG12 - BROWN GRADUATED This lens is the same as the SG12 but with a brown tint.
