When choosing a refractive index, you can consider the following:
1. Degree selection: For low myopia (0-300 degrees), choose lenses with a refractive index of 1.56; for moderate myopia (300-600 degrees), consider a refractive index of 1.67; for high myopia (above 600 degrees), a refractive index of 1.74 is recommended.
2. Lens thickness: The higher the refractive index, the thinner the lens, which is suitable for users who want a thinner lens edge.
3. Imaging quality: The Abbe number of high-refractive index lenses is usually low, which may increase dispersion and affect imaging quality. Therefore, clarity and thinness need to be weighed when choosing.
4. Usage scenarios: If you do not wear glasses frequently, it may be more appropriate to choose lenses with a lower refractive index.

It is well known that when wearing glasses for the first time, the eyes need to readjust to the new optical correction, which may cause temporary visual discomfort, such as dizziness or headaches. Over time, the body adapts to the new vision state, and the discomfort will gradually lessen or disappear.
For Example :
If You Need Presbyopia +2.5 , Please Purchase +250
If You Need Myopia -1.75 , Please Buy -175
