Fogging of glasses when working in difficult or fluctuating temperature conditions (when the temperature drops, when moving from a warm room into freezing conditions or back, or with increased air humidity) significantly limits the ability to work effectively.
When even the slightest discomfort occurs — for example, when vision through the goggles is poor — a person's first instinct is to take them off, especially if fogged goggles interfere with performing work accurately and correctly. But without protective goggles the worker's health is at risk, since the likelihood of flying particles entering the eyes increases significantly.
To prevent fogging, a special coating is applied to the lens. Safety goggles with this coating — are an effective way to ensure the safety of those working in changing temperature conditions.
