Understanding Color Lenses and Eye Health

Wearing color or circle lenses does not change how the wearer perceives the world's colors due to the design and potential health risks.

### The Science and Risks of Colored and Circle Lenses: A Comprehensive Guide
* 👀 Colored lenses are primarily cosmetic, designed to **change eye color for aesthetic purposes** rather than vision correction.
* 🌈 When worn, the colored part of the lens does not affect how the wearer sees the world, as it is designed to **mimic iris color for others' perception**.
* 👁 Circle lenses, popular in some communities, have a clear center for the wearer's vision, making the **color effect only visible to others**.
* 🚫 Improperly fitting lenses can **scratch the cornea**, **reduce oxygen supply**, and potentially lead to **serious eye health issues**.
* ⚠ Prolonged use of these lenses can cause **corneal inflammation, new blood vessel growth, and other complications**.
* 📊 There is no scientific evidence to support claims that these lenses affect **pupil size or eye health** in any significant way.
* 👩 Ophthalmologists recommend caution and proper care when using colored or circle lenses to avoid **potential eye health risks**.

This video is a content created by restructuring the knowledge of eye protection based on the manuscript written by the ophthalmologist, Jeon Jae-in. On sunny days, many people wear sunglasses to protect their eyes from the intense sunlight. However, due to the color of the lenses, everything looks dark after wearing them. This raises a question on the topic. If you wear lenses that directly change the color of your eyes, such as colored lenses or circle lenses, will you see the world in that color? If you have had the experience of wearing them, you probably know that it's not the case. It is uncertain how many people have experienced it, but generally, men tend not to wear them often, while about six out of ten women have had the experience. For those who have not had the experience, they may have had similar curiosity about the topic. I would like to discuss why things do not appear in the color of the colored lenses when worn, and also talk about health information that should be known when wearing them.

Color lenses can correct vision, but their main purpose is cosmetic. Basically, they are made to resemble the iris, allowing you to color the desired color and make your eyes appear as if the color of the eyes has changed when seen by others. The iris plays a role in focusing through the pupil, even though there may be differences in the color visible due to variations in pigmentation by race. Circle lenses are designed similarly, where the part looking at the actual office is transparent, so when the wearer looks with their eyes, it appears as if they are wearing regular lenses. If you have no experience wearing them, you may not have seen the product separately, so you may not have known well. However, when wearing lenses in your eyes, there is often a confusion phenomenon where the lens does not follow the pupil properly. This phenomenon mainly occurs with color lenses or circle lenses, where pigments and patterns are inserted.

Thicker and more rigid than regular lenses, they don't fit well on the eye's curvature. Then, how would it look if the colored part covers the pupil? Would the world appear in that color like sunglasses? Color lenses are typically made focusing on coloring rather than optical benefits, as mentioned earlier. If the colored part covers the pupil, it won't be visible depending on the degree of pigmentation. Because they are made this way, extra caution is needed when using them. Wearing lenses that don't fit well on the eyes can cause minor scratches on the cornea as they rub against the pupil or apply uneven pressure on the eye's surface, deforming the cornea. Also, the oxygen permeability of these lenses is relatively poor, so prolonged wear can lead to inadequate oxygen supply to the eyes. This can cause issues with the cornea.

Inflating or distorting can cause ambiguity and new blood vessels may develop to obtain oxygen. If abnormal blood vessels occur, various side effects such as visual impairment and corneal cloudiness may arise, and treatment can be difficult. Therefore, wearing color lenses this year is not good for eye health. Lastly, there is no scientific evidence or reported data related to the claim that pupils shrink and enlarge when wearing color or circle lenses. If we speculate why such misunderstandings arose, it could be due to the misconception that when blood vessels develop, the whites of the eyes enlarge, and if iris inflammation occurs leading to iris adhesion, the shape of the iris changes and may appear smaller, causing misunderstandings. Have your curiosity been resolved?

The Impact of Colored and Circle Lenses on Vision

Wearing sunglasses on sunny days protects the eyes from intense sunlight, but it also darkens the vision.

Colored and circle lenses do not make the wearer see the world in that color, and this experience is more common in women than men.

These lenses are primarily cosmetic and designed to change the appearance of the iris, but they can also cause confusion in vision by not following the pupil properly.

Color lenses are thicker and less flexible, which can cause discomfort and even minor corneal scratches.

If the colored part covers the pupil, it may not significantly affect vision, as they are designed more for aesthetics than optical benefits.

The poor oxygen permeability of these lenses requires caution and limits their recommended wear time to avoid corneal issues.

Wearing color lenses can lead to the development of abnormal blood vessels and various side effects, impacting eye health.

There is no scientific evidence to support the claim that pupils shrink and enlarge when wearing these lenses.

Misunderstandings about the effects of color lenses on the eyes may be due to misconceptions about eye appearance changes.
