The quality of the eyeglasses chain stores is relatively stable and reliable.
As the eyewear chain enterprises spread across the whole city or across regions, they occupy a large share of the local market, and the resulting scale effect reduces their own procurement costs and greatly enhances the awareness of brand quality. Therefore, the procurement of eyewear products is critical. Those defective products are much less likely to appear in these chain optician stores, which naturally ensures that overall product quality improves.

How Should Glasses Fit?
Make sure your pupils align correctly. The combination of frame, arm, bridge, and lens measurement can affect the placement of your pupils within your lenses, which is essential to the proper function and comfort of your prescription. To ensure glasses fit properly, the pupils should align horizontally in the center of your lenses.
Also, you should consider your face shape. When choosing a pair of suitable glasses, you should consider what face shape you have.
What is the cheapest way to buy prescription glasses?
The choice of frames is not only good-looking but also has a lot to do with whether the polished glasses can be worn correctly. Therefore, special attention should be paid to the selection of spectacle frames, and the pupil distance and the optical center of the spectacle lens should be placed in a suitable position. It should also match the shape of the face so that the paired glasses are not only beautiful but also comfortable to wear. If you don’t choose a frame according to this, but choose anyone according to the general rules, the pupils will not match the optical center of the glasses, and the deflection center of the glasses will appear, causing the prism effect, which is very harmful to the eyes. How do choose a frame? Glasses are worn on the face after all, and they have a decorative effect, so you still have to see if they fit your face shape. In addition, the weight should be light and the frame size should be appropriate. It is best to measure the interpupillary distance, otherwise, it is easy to cause squint and cross-sight. It is safer for children to choose a plate frame with resin lenses. There is a wide range of options for adults. Glass lenses have higher hardness and are not easy to wear, while resin lenses have lower hardness but lightweight, good clarity, and higher protection against ultraviolet rays. Although crystals are expensive, they have high ultraviolet and infrared transmittance.
The nose pad

Disadvantages of Plastic Frames
The disadvantage of injection molding material is that most of them have surface spray paint processing. They are not wear-resistant, easy to fade, easy to peel off the paint layer. PC material comfort is poor, and durability is not good. The frames cannot be changed to suit different face shapes. Because of its good elasticity, TR material can not be changed, which means that poorly made lenses are easy to fit into the frame. Plate material is hard, if the change is not appropriate, it will be not comfortable. Acidic material can not match the lens made of PC material, which will cause the lens to crack.
