1, the eye patch only protects the eyes.
Eye patches on the market now generally contain polyvinyl alcohol, sodium hyaluronate, glycerol and other ingredients. Among them, polyvinyl alcohol (PVA) is an extremely safe polymer organic substance, which is non-toxic and has good biocompatibility, especially in the medical field. For example, its aqueous gel is widely used in ophthalmology, wound dressing, artificial joint and so on. Therefore, eye patch helps to relieve visual fatigue.
2. It can relieve asthenopia, but it cannot eliminate asthenopia.
People must close their eyes when using eye cream. Using eye protection patch can relieve the symptoms of redness and astringency of eyes, but it can't fundamentally eliminate eye fatigue. The curative effect is not obvious, and it is impossible to prevent myopia and amblyopia. It should be noted that you can't open your eyes immediately after using the eye protection patch.
Eye patch can relieve eye fatigue, but it can't treat eye diseases.
At the current level of scientific research, eye patches can't cure eye diseases such as cataract and presbyopia.
4. Eye protection paste has better effect.
Eye drops, eye care solution, etc. They must be used within one month after opening, otherwise they will go bad. Moreover, most of them contain preservatives and should not be used for a long time. As a disposable product, eye patch has better eye protection effect and no worries about preservatives, and can be used as eye health care products for a long time. Because people's eyes are more important, the ingredients of eye patch now will be more scientific and pure. Therefore, compared with eye drops and eye protection solution, eye protection patch will have more market. I hope I can help you.
