Correct the report on 'Color Lens, Rough and Thick, Risk of Wounds'…
Recommended to wear for 4 hours, it could let people perceive color contact lens as negative thing.
Recently, there are reports that the color lenses are thick, and thus there is a high risk of injury. Therefore, there is a need to correct them.
Colored contact lenses have been loved by 10s&20s women, the main consumers of contact lenses.
Because color lenses have added the function of visual correction with beauty.
Only, color lenses are considered as beauty products and can be neglected in hygiene management. Particularly in times like these, where the risk of Covid-19 is high, more care is needed.
However, this is not related to the function of the color contact lens itself, and is a part that requires attention by the wearer. Nevertheless, the article calls the color lens material itself into question.
article said “Color lenses have low oxygen permeability, unlike clear contact lenses, so the recommended wearing time is also short, after 4 hours, taking out the colored lens to rest on the eyes is one of the ways to reduce side effects and maintain eye health.”
Then, the color lens inserts a dye to apply various colors. During this process, the surface of the color lens becomes rougher and thicker than a normal contact lens. It hurts the cornea, also, the thicker thickness lowers the oxygen permeability and results in delaying (=postponing, putting off) the injury recovery.
It is said that low oxygen permeability causes hypoxia, which creates new blood vessels in the conjunctiva of the periphery.plus, you have to be careful in severe cases as it can threaten visibility.
Of course, if you spend a little time managing contact lenses, the above problems can be caused. However, if worn after proper care, there is no problem in wearing.
An optician in Seoul said, “The wrong news like that can make a mistaken impression, so it will have to be fixed immediately.” However, since the average age group of wearing color lenses is getting lower, the opticians also need to clearly say the correct wearing and management methods to consumers. "There are cases in which young students wear or remove lenses without washing their hands outside. At this time, special attention is required because bacteria in the hand can be transferred to the lens," he said.
