Is it better to use monthly or annual contact lenses? What is the appropriate diameter?

Colored contact lenses are worn inside the eyes, so it is better to understand the relevant knowledge. Is it better to wear them monthly or annually? What is the appropriate diameter of cosmetic contact lenses?

Is it better to use monthly or annual contact lenses?

Monthly disposable cosmetic contact lenses are better than annual disposable ones, because annual disposable ones are used for a longer time, which will lead to more lens damage and protein precipitation than monthly disposable ones, and the safety risks are much higher than monthly disposable ones, so monthly disposable cosmetic contact lenses are better than annual disposable ones.

What is the appropriate diameter of the cosmetic contact lens?

Step 1: Understand what the diameter of the cosmetic contact lens is

The diameter of the cosmetic contact lens refers to the maximum straight-line distance between two corresponding points on the edge of the lens. Generally, the diameter of cosmetic contact lenses is between 13.8mm and 16mm.

Step 2: Understand the diameter of your black eyeball

The average diameter of Chinese people's eyeballs is about 11.5 to 12 mm. You can measure the diameter of your own eyeballs in front of the mirror with a ruler to get more accurate data.

Step 3: Understand the diameters of contact lenses available on the market

The most common diameters of cosmetic contact lenses on the market are 13.8mm, 14mm, and 14.2mm. Diameters above 14.5mm are relatively rare.

Step 4: Choose the diameter of your own cosmetic contact lenses

The larger the diameter of cosmetic contact lenses is, the better. Generally, a diameter of about 14mm is more appropriate. Even if the baby has big eyes, a diameter of 14.5mm is sufficient. Generally speaking, any contact lens larger than 14.5mm will be considered exaggerated and is not recommended to be tried lightly.
