The principle of choosing the cheapest eyeglasses frame for high myopia is "as small as possible and large enough". Try to be as small as possible. You can choose a small frame instead of a large one. Being large enough does not pinch the head and can stably wear on the face.

Of course, other factors affect the thickness of the lenses after matching, such as the higher the degree, the thicker the thickness, the lower the refractive index, and the thicker the material of the frame (the same in reality).

Only by following the principle of "as small as possible and large enough" can we choose a more suitable cheapest eyeglasses frame size and match the thinnest possible lens thickness.

I think the size of the frame has a greater impact on thickness than other factors, and there is no need to spend more money like increasing the refractive index, achieving the goal of being thinner without choosing high refractive index lenses.

If you understand, did you save money? For those with high myopia, you know how to pair them with light and thin discountglasses!

Talking about the factors that affect the thickness of lenses: Customers always ask how thick my lenses are when paired. Believe me, I hope to know more than you how many millimeters thick it will be after matching.

The influencing factors include the size of the framework, and the amount of displacement is the truly essential factor that determines thickness. Myopia film has a thin center and thick edges. So the thicker the edges are, the thicker they become. The size of the pupil distance can also affect the thickness and degree of the lens. Everyone understands this.
