How Can I Keep My Riding Glasses from Fogging Up?

Fogged lenses. It’s a very common problem for motorcycle riders. The cause is no mystery: humidity caused by changing temperatures. But temperature swings are fairly unavoidable where riding is concerned. Right from start, fighting lens condensation is an uphill battle; riding glasses sit in our temperature-controlled homes and reach room temperature, and are then exposed to substantially warmer or colder temps when worn outdoors. Hence a layer of recurring fog that needs constantly to be wiped down…no easy task, and certainly not a safe one while on a motorcycle in motion.

Bike riders often venture out during early mornings or late evenings – times when the traffic on the road is at a minimum and conducive to pleasant, stress-free enjoyment of some open pavement. Unfortunately, mornings and evenings are the times of the day when temperature swings are most prevalent, leading to moisture on your lenses. Combine that with the body heat of your face and forehead, which is already enclosed in a helmet and possibly exposed to a lot of direct sunlight, and keeping your riding glasses from fogging is a nearly impossible chore.

Impossible, that is, if it isn’t avoided with a little preparation long before you grab those glasses and your keys to head out to the garage. There are two ways to combat lens fogging: have an anti-fog coating applied when you first order your riding glasses, or apply one yourself, periodically.

Whether your glasses contain prescription or non-prescription lenses, optional coatings are available when you order them. One of these is a permanent anti-fog coating. It’s a chemical dip that is typically applied after your lenses are cut, ground, edged, and polished, and is then heat-cured so it does not wear away. This coating works on a molecular level to prevent miniscule water droplets from pooling up and combining into larger drops that obscure vision.

If you’re already comfortable with the glasses you own, and wish to prep them to better resist fogging, a number of anti-fogging agents are available. These include:

Fog Free Lens Coating

Fog Free Lens Coating – in a two ounce pump-spray bottle.

Cat Crap Anti-Fog Paste

Cat Crap Anti-Fog – in a paste format for rub on, rub off protection, available individually or in a care kit that includes a microfiber cloth and multi-headed optical screwdriver.

Cat Crap Anti-Fog Spray
Cat Crap Anti-Fog – in a spray-on format, available by itself or as part of a larger cleaning care kit that includes a microfiber buffing cloth and optical screwdriver.

You simply apply one of these products to your existing lenses, buff it out, and it acts in the same manner as a lens anti-fog coating, dispersing water droplets so they do not combine and grow in size. Since this method forms only a temporary coating that eventually wears off, self-applied anti-fog agents do need to be reapplied at recommended intervals. Their small containers, however, make them easily portable in saddlebags or jacket pockets.
