Why should you choose thin lenses?
Regular lenses are great for low-prescription people, but for high-prescription people, high-prescription regular lenses are too thick and heavy, making them unattractive and have a poor wearing experience. For high-prescription people, we recommend that they choose thin lenses with a high refractive index because they are lighter and more attractive to wear. For any astigmatism above +3.00, we recommend 1.67 or 1.74 refractive index lenses because these lenses are aspherical in design, which means they are thinner, flatter, and lighter than standard spherical lenses, which reduces the magnification of your eyes to other people.
