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.
But, a light frost can form with an average air temperature somewhere between 33 and about 37/38. Some surfaces radiate heat better than others, which is why you will get frost at times on elevated surfaces such as car windshields, blades of grass, roofs, or mulch when nothing else is frosty. hard or killing frost is when it gets below 29 or sub-freezing temps are prolonged (more than 24 hours). Plants are much better able to survive a light frost. Once you get below 28 degrees and beyond 6 hours below freezing, plants are much more susceptible to damage.
