Eye Glasses Fogging with a Motorcycle Helmet?

It’s common. It’s annoying. And it can be so much more than just a hassle; it can be dangerous, even life-threatening. No one likes it when their eyeglasses fog up, but it’s an especially critical issue when it happens while driving a motorcycle. And it happens often, for reasons outside of anyone’s control.

Lens fogging is caused by a rapid change in temperature. This is why your eyeglasses fog up when you enter a heated building after being outside on a cold day. As the lens surface adjusts to the new temperature, condensation evaporates; this often takes several minutes, however…and that’s several minutes of partially or completely impaired vision. In most cases you simply wait for your lenses to clear, or remove and wipe off your glasses – but that’s not an option on the back of a bike in motion and under your control.

Fogging on motorcycles is even more common because rapid temperature swings are part of the package. Most of your body heat is vented through the top of the head. When you put a helmet on top of your head it’s like putting a lid on a simmering pot; trapped heat raises the temperature inside the pot (or helmet). Couple that with sun beating down on you and temperatures around your face can climb fairly high. Then you hit the road to enjoy the breeze, cool air strikes your warm eyeglasses…and your lenses fog.

There are a few different ways to combat lens fogging. One depends on the type of eyewear you use when you ride. Several companies that specialize in motorcycle eyewear, including Bobster and Wiley X, have designed riding glasses and goggles with built-in ventilation systems that allow cool air to displace the warm. These designs maintain a fairly even temperature right at the lens surface, effectively eliminating condensation.

Ventilated motorcycle glasses or goggles are available at Rx Safety in either prescription or non-prescription formats, and are intended to replace your regular eyeglasses when you hit the road. If you’re a serious motorcycle enthusiast who rides often or you frequently ride in humid or hot weather conditions, a pair of motorcycle safety glasses specially tailored for the activity and the unique challenges it presents are probably your best bet.

All other options involve an anti-fog lens coating. These coatings prevent water molecules from pooling up into vision-obscuring mist. They can be permanently applied and sealed to provide maintenance-free service at a very economical cost, but this must be done when your eyeglasses are ordered. If you already have a functional pair of glasses that are not yet due for replacement, you can apply one of several “wipe-on, wipe-off” anti-fog agents directly to your existing lenses. 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.
