The following are the methods to distinguish the quality of plastic glasses:
1. Observe the appearance: high-quality plastic glasses have a smooth appearance without obvious flaws, spots and scratches. The printing, engraving and coating of the lens, temples and other parts should be clear and uniform, without falling off or blurring.
2. Check the quality of the lens: high-quality plastic lenses should have good light transmission performance, without obvious color difference, scratches and bubbles. You can check the light transmission performance of the lens by holding the lens in front of your eyes and observing the distant scenery. If the scenery is clear, without deformation and obvious brightness difference, it means that the light transmission performance of the lens is good.
3. Touch the surface: the surface of high-quality plastic glasses should be smooth and without obvious bumps. You can feel its smoothness by touching the surface of the lens with your hand. The smoother the lens, the less likely it is to get dirty and the easier it is to clean.
4. Check the anti-fouling ability: high-quality plastic glasses should have good anti-fouling ability and are not easily stained with fingerprints, oil stains, etc. You can check its anti-fouling ability by gently wiping the surface of the lens.
5. Pay attention to details: high-quality plastic glasses should be very delicate in detail processing. For example, nose pads, hinge sound, whether the pile head is seamless, smoothness, electroplating appearance, whether the logo is clear, etc. are all important indicators to measure the quality of glasses.
6. Check the packaging and origin description: High-quality plastic glasses usually have complete packaging, tags or instructions, which contain detailed information about product descriptions, industry quality standards, and dealers or manufacturers. This information can help consumers understand the source and quality assurance of the product.
In short, identifying the quality of plastic glasses requires comprehensive consideration of appearance, lens quality, surface smoothness, anti-fouling ability, detail processing, packaging and origin description. Consumers should observe and check carefully when purchasing and choose products with reliable quality.
