Beauty with treatment** Colored medical lenses are a special type of contact lenses that, in addition to correcting refractive errors such as myopia, farsightedness, and astigmatism, also provide the possibility of changing eye color.

The main use of these lenses is for people who need vision correction but at the same time want to change their eye color temporarily. The use of colored medical lenses is considered a dual-purpose solution that brings beauty to the eyes in addition to clarity of vision. **Why choose colored contact lenses?** Many contact lens wearers have initially looked for a way to replace glasses.

At the same time, these lenses provide the possibility to change or enhance the natural eye color. This combination of aesthetic and therapeutic lenses eliminates the need for simultaneous use of glasses and non-medical colored lenses and brings more comfort to lens use. ### **Increasing self-confidence and more comfort** Modern colored medical lenses with advanced technologies provide more comfort during the day. The materials used in these lenses allow sufficient oxygen to pass to the cornea, thus preventing dry eyes. Choosing diverse and natural colors also gives users more confidence and allows them to have a new and attractive look in different situations. **Dangers and possible side effects of contact lenses** When does beauty end at the expense of health? In response, it should be said that if the management is not done correctly, there are hidden dangers and serious complications for eye health. Non-observance of hygiene and principles of lens use can put any person under threat. One of the most common and serious complications is eye infections. Bacteria, fungi and viruses easily stick to the surface of the lens and enter the eye. These infections, from conjunctivitis to dangerous bacterial keratitis, can lead to severe pain, blurred vision, and even permanent vision loss. Corneal abrasions, a common complication, may be caused by foreign particles, dry eyes, or ill-fitting lenses. These scratches are not only painful, but can pave the way for pathogens to enter. Another side effect of these lenses is allergic reactions that people's eyes may react to the lens materials or solutions, and it is usually accompanied by itching and redness of the eyes. Long-term use or sleeping with lenses can reduce oxygen supply to the cornea (hypoxia). This lack of oxygen, in turn, leads to the growth of new blood vessels and ultimately, blurred vision and vision problems. These complications can be easily avoided by following the doctor's instructions and taking proper care of the lens. **Read more: Guide to buying standard sunglasses to protect the cornea** **Correct use and maintenance of lenses** Correct use and careful maintenance of colored contact lenses is necessary to maintain eye health and prevent infections and side effects.
