Why Do Prescription Glasses Fog Up?

Prescription glasses fog up primarily due to temperature differences and humidity. When warm, moist air meets the cooler surface of the lenses, condensation occurs, leading to fogging.

According to the American Optometric Association (AOA), fogging on lenses happens when moisture in the air collects on surfaces that are colder than the dew point, which is the temperature at which air becomes saturated with moisture.

The underlying causes of fogging can be broken down into two main parts: temperature variations and moisture levels. When individuals exhale warm air, it can rapidly vaporize and cool upon contact with the cooler lenses, forming tiny water droplets. The level of humidity in the air also plays a significant role. High humidity increases the amount of moisture available to condense on the cooler lens surface.

Fogging can occur in situations where warm, moist air interacts with colder surfaces. Specific actions can exacerbate this issue, such as wearing a face mask while outdoors in cold weather or transitioning between warm indoor environments and chilly outdoor air. Activities like cooking or exercising can also contribute, as they generate heat and moisture, further increasing the likelihood of fogging.

In summary, fogging occurs when warm, moist air meets cooler glasses, leading to condensation. Environmental factors such as temperature differences and high humidity levels play significant roles, resulting in this common issue for eyeglass wearers.
