According to a study, there is a coating in our eyes which is made up of lipids (a kind of wax like substance) which plays a vital role in avoiding vaporization of tears and thus the steadiness of the tear film is maintained. Some people are not at ease wearing contact lenses, and this might be because of deterioration of the lipid coating in eyes.
The study also showed that certain kind of changes were seen in the lipid coating of the people who do not feel comfortable after wearing contact lenses. It was further added that the fear of uneasiness is the main reason why many people do not prefer wearing contact lenses.
Experts say that eyelid spray helps in wearing contact lenses as it helps in lower the vaporisation of tears, thus making the person feel comfortable.
