Transparent contact lenses, also known as ordinary contact lenses, are products designed for myopic people who are not accustomed to wearing framed glasses. Colored contact lenses are a type of contact lenses. They first appeared in South Korea and have gained the favor of many beauty enthusiasts with their beautiful shapes and bright colors. However, some consumers are not very clear about the differences and commonalities between the two when choosing contact lenses.
The main functions of colored contact lenses are reflected in enhancing light, enlarging, darkening or changing the color of the eyes, which is essentially embedding the color between two pieces. In contrast, transparent contact lenses are transparent and colorless, with only one layer.
In terms of appearance, colored contact lenses are more attractive than transparent ones. Some brands of colored contact lenses even have lace edges, making the eyes look more dreamy.
Compared with transparent contact lenses, colored contact lenses have poorer oxygen permeability and anti-protein precipitation ability, are less comfortable, and are prone to dryness.
Warm reminder: Regarding the wearing time, since the oxygen permeability of colored contact lenses is not as good as that of ordinary contact lenses and there is relatively more protein adhesion, the wearing time is shorter than that of ordinary contact lenses. The daily wearing time should not exceed 8 hours.
Even if you like the newly bought colored contact lenses very much, you should not wear them immediately. This is because the original colored contact lenses are soaked in physiological saline. Wearing them at this time will not only cause irritation but also affect the health of your eyes. Newly purchased color films should first be rinsed with care solution and soaked in fresh care solution for more than 4 hours. They still need to be rinsed once before use.
If you don't wear colored contact lenses for a long time and want to wear them the next day, you should carefully clean the lenses the night before. Only when the lenses are kept clean can you ensure the health of your eyes. Nowadays, many people like to use hydrogen peroxide care solution. However, due to the manufacturing process, some colored contact lenses are not suitable for frequent use of hydrogen peroxide care solution.

What is the base arc of contact lenses?
The base arc is a very important parameter that distinguishes contact lenses from frame glasses. The so-called base arc refers to the radius of curvature of the lens. Figuratively speaking, the larger the base arc of the lens is, the flatter the inner surface of the lens will be. If the base arc of the lens is larger than that of the eyeball, the lens will not fit the eyeball properly and is prone to displacement, which is known as slippage.
The main manifestations of a large base arc are that the wearer has a strong foreign body sensation, feels that the lens is wearing the eyes, and is about to come out of the eyeball at any time. On the contrary, if the base arc of the lens is smaller than that of the eyeball, it will easily cause the eyes to feel overly tight and uncomfortable. Of course, from a practical perspective, the base arc of contact lenses cannot exactly match that of the eyeball. When purchasing, it is advisable to keep it within 0.2 millimeters as much as possible.
