Is it better to have a larger base curve of the beauty contact lens? What is the appropriate base curve of the beauty contact lens?

Many people have worn cosmetic contact lenses, which are also a common type of contact lenses. So is the larger the base curve of the cosmetic contact lens, the better? What is the appropriate base curve of the cosmetic contact lens?

Is it better to have a larger base curve of the contact lens?

No, it's too big and easy to fall off. The base curve refers to the curvature of the cosmetic contact lens, the radius of curvature of the optical center area of ​​the inner surface of the lens. Lenses with a base curve of 8.4-8.6mm can better suit the vast majority of girls. However, since cosmetic contact lenses are directly attached to the eyeball, the curvature of the lens must match the curvature of the eyeball as much as possible to achieve the most suitable wearing effect. If you have not gone to the hospital to measure the radius of corneal curvature, choose lenses that are slightly looser, because slightly tight lenses can easily cause eye soreness.

What is the appropriate base curve of the beauty contact lens?

The average eye arc of Asians is between 8.4mm and 8.6mm. The difference between the base arc of the cosmetic contact lens and the arc of the eyeball should be controlled within 0.2mm. The base curve is used to determine whether the lens is adapted to your corneal curvature to provide the best fit and comfort. Before purchasing cosmetic contact lenses, it is recommended that you determine the base curve of your eyeball at a regular ophthalmology hospital. The base curve (BC) is the curvature of the back surface of the contact lens optical zone, and its size is expressed by the radius of curvature of the lens. The smaller the base curve, the steeper the curvature of the lens. If it is smaller than the base curve of the eyeball, it will cause discomfort such as tightness and pressure. The larger the base curve, the flatter the inner surface of the lens. If the base curve is too large, the lens will not fit the eyeball and will often shift.
