More about size

For a better complement of comfort and aesthetic functionality when buying single vision eyeglasses, wears with high prescription strength on the SPH and CYL please note that Positive lenses are not supposed to be fitted with smaller frame and Negative lenses are better of staying away from very large frame.
Higher index lenses like 1.60 and 1.67 can solve the problem of having thick edge on the Negative lenses or thick center of the Positive lenses by providing with the maximized vision effect and wearing comfort, much more lightweight and thinner.
For the wears that have a comparatively small PD (the distance between your pupils is less than 58mm), please be cautious of the total width of the size because larger frame may not match your PD. Smaller frame should be considered firstly in order to promise the vision acuity.
All the pictures presenting on the page are just for the reference purpose. It is recommended that you measure the size of your old frame before ordering.
