Many people can have them without experiencing any symptoms. The problem can arise when their number increases significantly or when they coincide with certain alterations of the ocular surface and eyelids.
In these cases, irritation and inflammation may develop around the eyelashes.
Signs that may appear on the eyelids
When there is a significant proliferation of Demodex or other forms of blepharitis, some people may experience different discomforts.
These may include itching around the eyelashes, burning sensation, redness of the eyelids, eye irritation, and accumulation of residue around the base of the eyelashes.
While we sleep, our skin comes into contact with the sheets and especially the pillow for several hours.
Fat, sweat, dead cells, and cosmetic residue can accumulate in tissues.
For this reason, it is advisable to wash bedding regularly, particularly pillowcases.
This is part of good general hygiene, although it does not mean that a pillow used for a few days will automatically cause eye disease.
