The selection of a discountglasses frame requires consideration of three most important issues: materials science, aesthetics, and optometry. Even some psychology needs to be mixed in. Common selection indicators for daily glasses as a reference.

What kind of discountglasses frame is lighter and more comfortable to wear? If you like metal frames, it is recommended that you choose pure titanium frames. Inside the metal frame, which we often come into contact with in daily life, pure titanium frames are lighter, more stable to wear, and have a better texture.

There is also a high-end titanium alloy that is lighter and structurally better than pure titanium, commonly found in high-end mirror frames. Next are bio steel and beta titanium. Finally, we recommend ordinary alloys.

If you don't like metal materials or are allergic to metals, we recommend choosing TR90 material and ultra-light board. Not recommended for ordinary board materials. The TR90 material is lighter, the color is more beautiful, and the price is relatively affordable. Ultra-light board retains the texture of the board, which is lighter than ordinary board, but at the same time heavier than TR90. The price is also relatively expensive and often appears on high-end brands.

Choose the size of the eyeglasses online cheap frame based on your luminosity and pupil distance. When the myopia is below -3.00 degrees, the size of the frame can be freely selected, and you can be a bit arbitrary, just like it yourself. Customers with myopia above 4.00 degrees should try to refer to their pupil distance and choose a frame that is close to their pupil distance size.

Meanwhile, under the premise of personal preference, the smaller the size of the lens, the better. This choice not only makes the lens lighter but also makes the edges of the lens thinner.
