There are many options when choosing shades, but when we talk about sports eyeglasses, it get’s a little complicated.Usually, making a prescription eyeglass with shades is easy, you just choose the frames and the lens color and you have it. But this works only with prescription eyeglass frames, because the shape of the frame is standard and the lens can be mounted easy.but for sports glasses, You have to know that an extra-curved lens if made with diopters, will modify the way you see through it, because of the curve, so an adaptation period is required so there is a possibility that you will not accommodate with them. This is why they choose to put the inside clip, which does not require extra curved lenses, but standard lenses, so the adaptation is easier. Also, the mounting of the prescription lenses is more easy.The other thing is that the frame is extra-hard, so even if you got the best lenses, the mounting process is difficult and you have to find the right optician to do it.
