Precautions for lens purchase
Jul 20, 2021
1. Good lenses, material is the key
The material of a pair of lenses plays a decisive role in the light transmittance, durability and Abbe number (visual effect of the rainbow pattern on the lens surface) of the lens. In-depth research and development can be carried out on materials, with controllable quality and excellent performance.
2. The film layer makes the lens easy to wear
A good lens film layer can give the lens more excellent performance, not only the optical properties such as transmittance are greatly improved, but the hardness, wear resistance, and durability will be greatly improved.
3. Practical functions, suitable for eye scenes
The most suitable is the best, and different occasions need to correspond to the purchase of lenses with different practical functions. For example, people who use computers frequently can focus on anti-blue light lenses; people who frequently go outdoors and indoors can consider smart color-changing lenses; drivers can consider driving polarized lenses; people who exercise frequently should not consider super-tough lenses.
4. Visual effect, comfortable to wear
Lenses on the market usually include spherical, aspherical, double-sided aspherical, single-lens or multi-focal visual designs. Good visual design can enhance visual reality, relieve visual fatigue, and improve consumers' wearing experience.
