Optometry for prescription glasses
The key prerequisite for proper glasses is accurate optometry. In foreign countries, professional optometrists are generally required to be qualified to issue prescriptions for optometry. However, this is not very standardized in China. Many optometrists have only been trained for a short period of time and do not have the basic knowledge of ophthalmology. For some complex situations, they may not give a proper prescription for glasses. Therefore, optometry should choose a qualified institution. If you are adolescents, people with high myopia, people with anisometropia, etc., you may need to dilate your pupils for optometry. It is best to go to the optometry center of the hospital for optometry

Wooden frames are becoming more and more popular. As a material, wood is lighter, and it provides warmth, both in appearance and on the skin. These frames stand out in a relaxed, natural way. They have dark stripes, black temple tips, and spring hinges.
What are keyhole glasses?
Keyhole glasses have a keyhole bridge. The keyhole bridge is shaped like a keyhole and is located on one side of the nose. Bridge glasses are one of the most beloved styles in the history of optics. The keyhole bridge has the shape of a keyhole. The keyhole bridge is arguably one of the most popular eyewear features. With the rise of acetic acid frames in the 1950s, keyhole glasses became widely popular. The ductility of the new material allows for a simplified manufacturing process, thus creating room for creative experimentation in the frame development.
What Is an Aspherical Lens?
An aspheric lens is a lens whose surface profiles are not portions of a sphere or cylinder. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens.
The aspheric lens’s more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations such as astigmatism, compared to a simple lens. A single aspheric lens can often replace a much more complex multi-lens system. The resulting device is smaller and lighter and sometimes cheaper than the multi-lens design.
Aspheric lenses are flatter than traditional lenses, but they still offer the same vision-enhancing benefits. They have a more attractive profile because there is less curvature. In addition, aspherical lenses have a more complex front surface with a gradual curve so that they can perform better by improving the way light refracts onto the retina.
Besides, most aspherical lenses are high-index, which, when combined with the aspheric design, offers a slimmer and lighter option for people who wear glasses so as to improve the look and feel.
Adjustment of the upper and lower position of the nose pad
The nose pad can be pulled up and down with the pliers of the nose pad to achieve the purpose. You can use needle-nose pliers to clamp on the nose pad and apply torque in a certain direction to change the upper and lower position of the nose pad. When applying the torque, the nose pad can be pressed down or pulled up by the pliers to change the position of the deformation of the bracket, to prevent repeated deformation and fracture near the solder joint.
Memory titanium series
It has the features of strong elasticity, lightweight, and strong corrosion resistance. Set the essence of memory alloy frame design in one, they can better reflect the wearer's not common demeanor. It is very stylish and avant-garde, and the high-quality color fully highlights the perfect curve of the face.
Different Type of Lenses: How to Choose
Photochromic lenses: These lenses change from clear to tinted with sunlight. You may no longer need sunglasses although they may not darken in your car if the windshield blocks UV rays. They can be either glasses or plastic.
Polarized sunglasses: Polarized sunglasses can reduce glare from a surface like water, so they are great for sports and driving. But they can make it hard to see the liquid crystal display on your car’s dashboard.
As for different types of lenses, this post has introduced several kinds of. When buying eyeglasses, take these into consideration. If you need a pair of glasses, you can try Koalaeye glasses. They are stylish and come at a cheap price.
