Which kind of lens material is more suitable for long-term wear

Which kind of lens material is more suitable for long-term wear

Taking various factors into account, resin lenses are the most suitable for long-term wear due to their advantages of lightweight, safety and strong impact resistance. However, it is necessary to pay attention to maintenance to avoid scratches and aging. Of course, the specific choice depends on individual needs and budget. If the pursuit of extreme light transmission and wear resistance, and can accept its weight and fragility, glass lenses are also a good choice. PC lenses are more suitable for specific people who need high impact resistance.

Glass lens or resin lens which is better transmittance

Glass lenses and resin lenses have their own advantages in terms of light transmission. Glass lenses have extremely high transmittance, and resin lenses can also achieve excellent transmittance through precision machining and coating treatment. In the specific selection, it is necessary to consider factors such as personal needs, degrees, use scenarios and budgets. There is no absolute "which is better", only the choice that is more suitable for you.

Glass lens or resin lens which is less dispersive

Glass lens or resin lens which is less dispersive

It is not possible to simply say whether a glass lens or a resin lens is less dispersive, because it depends on the specific lens type, refractive index and material properties. Modern high-index resin lenses often provide good dispersion performance while maintaining high transmittance, comparable to or even better than some types of glass lenses. Therefore, when choosing lenses, a comprehensive consideration should be made based on individual needs and preferences and the advice of professional optometrists.
