Minimum diameter of contact lenses

Everything in life has a size. Frame glasses have sizes, and contact lenses also have sizes. Some people say that the diameter of contact lenses is generally 13.8mm-14.2mm, which makes the glasses look big. In fact, it is not like this. It is just a visual effect given by the radial pattern. If the diameter of the contact lens is small, the light in the visual area will be affected. The following is a detailed introduction to the diameter size of contact lenses.

The diameter of contact lenses is generally 12~14mm. Although many people buy cosmetic contact lenses with diameters of more than 15.00mm, it is not recommended to wear large diameter cosmetic contact lenses, which are not good for eye health. Moreover, if the diameter of the cornea of ​​the eye is not suitable for the diameter of the contact lens, it will not look good when worn. Therefore, the diameter of the contact lens is not the larger the better. The minimum diameter of the contact lens, of course, the appropriate diameter of the contact lens depends on the height of the wearer's palpebral fissure and the diameter of the cornea. The minimum diameter of the contact lens, the diameter of the RGP hard contact lens is 8~9.5mm. The diameter range of the contact lens that is comfortable to wear is 13.8mm~14.2mm. The minimum diameter of the contact lens, when choosing contact lenses, you should go to an ophthalmologist to have your eyes checked and fully understand the condition of your eyes, so that you can better choose a pair of contact lenses to wear, and it will be more comfortable to wear.

What is the best diameter for contact lenses?

The appropriate contact lens diameter depends on the wearer's palpebral fissure height and corneal diameter. All soft lens diameters are larger than the corneal diameter (expressed as HVID), while hard lens diameters are smaller than the corneal diameter but larger than the pupil diameter. The diameter of common soft lenses is 12~14mm, while the diameter of RGP lenses is mostly 8~9.5mm. Generally speaking, the diameter of transparent contact lenses is relatively reasonable and suitable for wearing.

However, the diameters of many colored contact lenses now exceed 14mm, and some products even exceed 15mm. Do not choose colored contact lenses with too large a diameter. The width of the palpebral fissure of Oriental people is usually less than 15mm. If the diameter of the colored contact lens exceeds the width of the palpebral fissure, it will cause symptoms of eye rubbing or affect the opening and closing of the eyelids. We recommend that the diameter of colored contact lenses should be between 14mm and 14.5mm, which can achieve both an enlarging effect and a comfortable wearing feeling. This allows us to harvest while also staying healthy.
