Where are the risks of colored lenses for the eyes?

Many people resort to wearing colored lenses for the purposes of following fashion trends, wanting to appear in a certain way, or they prefer other colors over their original eye color. However, many are not aware of the risks that may result from putting these lenses in the eyes.


In this context, Professor Tatiana Shilova, a specialist in ophthalmology, stated that colored lenses can prevent the necessary amount of oxygen from reaching the eye, which reduces visual acuity.


In an interview with URA.RU, the professor pointed out that “the requirements for colored contact lenses are more stringent than for optical contact lenses, because their oxygen permeability is much lower due to their colored surface.”

Also, the expert advised not to use these lenses for more than five hours a day, and it is best to use them on holidays and occasions. But before that you should consult an ophthalmologist.


She noted that colored lenses reduce visual acuity. Because, as a rule, the colored portion of such lenses occupies a surface area greater than the standard pupil size.


She said: “Coloring narrows the field of vision and limits side vision, even the pupil area, which reduces visual acuity, and this effect increases in the evening, because the pupil of the eye expands at night.”
