Lens is the most important component of glasses, which determines the visual effect of glasses. When selecting lenses, the factors you need to consider include the degree of vision correction, lens material, radiation resistance, scratch resistance, and lens function.

The degree of visual correction is the most fundamental consideration. Generally, myopic patients need to thin their thinner edges; Patients with hyperopia need to thicken the lens center. Of course, the professionals in the glasses store will recommend appropriate lenses based on your situation.

Lens material is also one of the factors that need to be considered when selecting lenses. Currently, commercially available lens materials include glass, resin, and ultra-thin materials. Compared to glass and resin, ultra-thin materials have the advantages of thinner lens thickness, higher light transmittance, and lighter weight.

The radiation resistance level is also one of the important properties of glasses. The electronic products we use emit blue light, which can cause fatigue in our eyes and even exacerbate eye diseases. Therefore, it is necessary to choose anti radiation lenses.

Scratch resistance is also one of the factors we need to consider when selecting lenses. Anti scratch lenses can prevent scratches, wear, and other problems in daily use of glasses, which can extend the lens life.

When selecting lenses, you also need to consider their functionality. For example, if you often drive, selecting pole control lenses can help you because they allow you to more clearly identify road signs, vehicles, and so on.

conclusion

Choosing the right lens for yourself is important because different needs require different functions. Therefore, when purchasing lenses, you need to make choices based on your needs to ensure that your eyes can receive the best protection and visual effects.
