One of the most common issues experienced by eyeglass wearers, is that the lens will tend to fog up in varied climates – which can additionally impair vision. To prevent this, check out the following tips:
Check the fit – ensure that the space between the eyeglass and your frame is sufficient to allow air in and out. This is known as a proper ventilation system. Sports sunglasses for instance sometimes carry an inbuilt vent to prevent any fogging that may occur while participating in sporting activities.
Buy custom anti-fog lens – there are frames and lenses on the market today that carry an anti-fog feature. Shop online to compare prices and varied brands. These can also include prescriptions for corrective vision.
Buy anti-fog solutions – which you can spray on the lens to prevent fogging for a certain period of time. Ensure that the solution is sprayed a good feet away from the eyes when applying.
Clean lenses – frequently, in order to prevent debris buildup which may accelerate fogging.
When heading to a new climate, the lens will tend to adjust to the new weather conditions after a certain period of time.
Most importantly, while driving, eyeglass wearers should set the air on a comfortable temperature so that the glasses become neither too hot, nor too cold – which can cause fogging – even inside a closed car.
