Giro Vanquish Shield

The onyx visor, the stock one that comes with the helmet, has a silver mirror and grey rose lens. The lens has relatively low light transmission suitable for bright sun conditions, acceptable for cloudy daytime conditions. I need to turn up the screen brightness on my head unit to improve readability when using this visor.

The emerald visor's mirror is green in the center and fades to purple at the left and right edges. The lens is a punchy pink tint. Light transmission is greater than the onyx visor, suitable for cloudy conditions or low sun and dappled shadows. This lens has a visible color shift based on the incident angle to the lens meaning if I look straight ahead through the lens, colors appear differently than when I look obliquely through the edge of the lens in any direction.

While the contrast boost that the emerald visor offers is sometimes helpful, I find the vividness to be unsettling to my nervous system. The onyx visor is better in this regard though I wish both were a softer tint.

Road cycling. Great protection for eyes both sun and debris. Very fragile so when placing them on the helmet and especially when taking them off the helmet do not torque or they will crack in the middle of the lens and the nose guard will fall off. Still usable though.
