Glasses, whether prescription lenses or bluetooth glasses, are essential daily tools. Proper cleaning ensures performance and longevity, but many damage them with incorrect habits. Here’s how to care for modern eyewear effectively.

    Understanding the refractive index is key for balancing aesthetics, comfort, and clarity in prescription lenses. Comparing 1.56 and 1.61 indexes, especially for smart glasses or Bluetooth glasses, helps choose the right fit for modern eyewear trends like prescription-enabled tech.

During the fitting process, we usually judge the customer's myopia type through the size of the corneal curvature and the length of the axial length of the eye, which are mainly divided into two categories.
Axial myopia: The degree of myopia mainly comes from the expansion and deformation of the eyeball. The length of the front and rear diameter of the eye is elongated, resulting in myopia.Curvature myopia: Mainly caused by the excessive bending force of the cornea on optics, which causes the optics to focus in front of the retina. This type of myopia is generally relatively stable, with normal axial length and no deformation of the eyeball. The probability of fundus complications is very low.
