**WIKI Wikishift **
Wiki has offered photochromatic visors for quite some time. In fact, the Wikishift faceshield was runner-up for Best New Product in our 2008 MOTY competition. Like Bell's SolFX visors, Wikishifts currently are only available for Wiki helmets, but the company provides a Wikishift faceshield with every lid and says fitments for other brands are forthcoming. The Wiki visor reacts slightly quicker than the SolFX faceshield and is less prone to darken on cloudy days, but it doesn't achieve as dark a tint and has a purplish hue when activated. It's enough to keep your eyes from becoming strained, but barely. It's not quite as convenient as the SolFX visor, but the Wikishift shield is much cheaper than Bell's offering and might be available for the helmet you already own in the near future.
