How to determine whether progressive lenses are worn correctly?
Once your glasses are back from the lab, the optometrist will let you put them on for an audition and make final adjustments to make sure they fit. If the prescription is not in the center of the lens, it will make it difficult for you to see clearly. The key is that the lenses match the wearer's eyes, especially the pupils. Before ordering a new lens, the optometrist takes two measurements: pupil distance and fitting height.

The optical studio has a range of carefully designed frames and precision lenses. There are many lenses to choose from. Transition lenses are made from dynamic materials and can replace prescription sunglasses. UV-coated lenses can be used in ordinary glasses. Scratch-resistant coating is a clear coating that helps protect glass lenses from irritating scratches. The plastic lenses make the glasses much lighter than the glass ones. Special polycarbonate lenses greatly reduce the thickness of the lenses, giving them a more attractive silhouette. Anti-glare lenses are dipped in a special material that makes them less reflective than regular eyeglass lenses.
The function of eyeglasses cloth
Under a powerful microscope, the fibers of the cloth are more closely arranged than those of ordinary cloth, and the material itself is softer than ordinary cloth. That's because eyeglasses under the eye are almost always coated, with each standard lens having seven layers of different functions on the front and back surfaces, to extend lens life. It can thoroughly remove the stubborn stains left on the lens to make the picture clear. It can clean all kinds of glass, resin, and other materials of glasses, glass mirrors, and other mirror surfaces, remove stains, and grease absorption.
What Are Pinhole Glasses?
Pinhole glasses, also called stenopeic glasses, are plastic eyewear with hundreds of pinhole-sized perforations in place of lenses. Pinhole glasses are mostly used to improve refractive errors in the eye because they shield the eye from indirect rays of light which can distort vision. This would decrease the blur circle on the back of the retina.

'Seeing the world better' is the goal that Essilor has always pursued, and 'people-oriented, winning with quality' is the basic point of Essilor's business philosophy. Essilor believes that the competition of talents is the foundation of all competitions.

Crizal lenses have excellent anti-fouling, abrasion resistance, anti-glare functions, and good light transmittance. Airwear lenses are PC lenses, and their chemical name is polycarbonate, which is a thermoplastic material. PC lenses are extremely tough and will not break (2cm can be used for bullet-proof glass), so they are also called safety lenses, which are currently the lightest materials used for lenses.

Acetate frame and plastic frame
What is the difference between acetate frame and a plastic frame? Acetate frames are lighter and generally considered to be better than plastic frames. Acetate is known for its hypoallergenicity, so it is a popular choice for people with sensitive skin. Unlike some plastic or metal frames, they can cause allergic reactions.
- The manufacturing process makes the plastic frame more brittle than the acetate frame.
- If the temple does not have a metal bracket, it is difficult to adjust the plastic glasses.
- There are fewer choices of colors and patterns for plastic frame
However, you will notice that acetate frames are generally more expensive than ordinary plastic frames. Spectacle frames are daily necessities that we use for a long time. Therefore, durability is essential, and the life span of the acetate frame is longer.
