Internal styes are infections of the meibomian sebaceous glands lining the inside of the eyelids. They also cause a red bump underneath the lid with only generalized redness and swelling visible on the outside.
Now frost is a covering of ice crystals on the surface produced by the depositing of water vapor to a surface cooler than 0Â° C (32Â° F). The deposition occurs when the temperature of the surface falls below the frost point.Similarly, dew forms when the air or surface temperature falls below the dew point temperature.herefore, frost is not frozen dew.). Thus, if the temperature on the ground or an object such as a bush or a car windshield near the ground falls below the frost point, frost crystals may form. But the measured  surface temperature  may still be above freezing.

Frost forms on objects when water vapor in the air condenses close to or on the ground. Farmers have developed ways of predicting and preventing the formation of frost on crops. They take into account different aspects of weather such as humidity, wind, clouds and the dew point to determine if there will be a frost.
