A wedge frame is a specific type of eyeglass frame where the outer edges of the rims are significantly thicker than the rest of the frame. This design is a lifesaver for people with high minus prescriptions. Because high minus lenses are thin in the middle but thick at the sides, a wedge frame acts as a shell that hides that side thickness, making the glasses look much sleeker.
read more about wedge frame ...Standard frames have a consistent thickness all the way around. A wedge frame increases the depth of the frame only on the outer sides where the lens is at its thickest. By encasing the lens edge in a thick wall of acetate or metal, the frame conceals the coke bottle effect that often occurs with strong prescriptions.
While the frame uses more material on the edges, many wedge frames are made from lightweight materials like titanium or high-quality acetate to keep them comfortable. The slight increase in frame weight is usually worth it for the massive improvement in how the glasses look from the side and top.
This style is highly recommended for anyone with a prescription of -4.00 or higher. If you are tired of your lenses sticking out past the edge of your frames, a wedge design is the best way to achieve a professional, polished look without having to buy the most expensive high-index lenses.
Wedge frames are most common in acetate because the material is easy to mold into thicker shapes. However, there are also milled titanium wedge frames that offer a very modern, industrial look while remaining incredibly light and strong for daily wear.
From the front, they look like normal glasses. The extra thickness is only visible from the side or top, and because it hides your lens edge, it actually makes the glasses look less bulky overall.
You can wear them with any prescription, but their main purpose is to hide thickness. If you have a very weak prescription, you might find the frame unnecessarily deep for your thin lenses.
Using high-index lenses along with a wedge frame will give you the absolute best result. The high-index material reduces the lens thickness, and the wedge frame hides whatever thickness is left, making your glasses look as thin as possible.
