How Do Prism Eyeglasses Work?
Prism eyeglasses use special lenses with a prism shape to bend light. This helps people with double vision, which occurs when their eyes don't focus on the same point. The prism adjusts the light entering the eyes, so both eyes see the same image, eliminating the double vision the brain interprets.
If you need prism correction, your prescription will include specific numbers indicating the vertical and/or horizontal angles needed to correct your vision.
Best Frames for Prism Lenses
Prism lenses can sometimes be uneven in thickness, with one lens being slightly thicker than the other. To better cover the edges of these lenses, you might prefer a thicker frame. However, if the thickness doesnโt concern you, you have full freedom to choose any frame style you like.
