Rimless Glasses with High Index Lenses

For some, the eyeglass frame makes a statement, and the bolder the better.

High Index Lenses in Rimless Glasses

Rimless Glasses with High Index LensesThey prefer frames that are conspicuous: thick brow lines, ornamentation, noticeable colors or patterned prints, any style that calls attention to itself. Others prefer the opposite approach and seek to tone down the frame as much as possible.

If you’re of the latter persuasion, rimless or semi-rimless frames are the way to go. Full rimless glasses suspend the lenses in front of your eyes with as little visible support as possible. Lenses mount directly to the temple arms, with an adjoining nose bridge; from the front, only the clear lenses are visible, appearing to float without any assistance from a frame. Semi-rimless frames utilize the overhead bridge, leaving the sides and bottoms of the lenses exposed for a lighter look. Both options offer a more open, less restrictive appearance than a full frame.

The key to the availability of rimless or semi-rimless frames is the weight and thickness of your lenses. The lack of a surrounding-mount frame results in a reduction in stability and durability, and because of the added exposure, rimless or semi-rimless lenses are more prone to damage than those mounted in full-frame styles. If your vision correction prescription is fairly or very strong, your lenses may be too thick and heavy to fit a rimless or semi-rimless frame style. Stronger prescriptions can also require a deep curvature, resulting in thick edges that are not aesthetically pleasing or simply do not fit a rimless or semi-rimless bridge.

If this is true in your case, high index lenses may provide an answer. High index plastic allows prescriptions to be cut using less lens material and with less of a curve, resulting in a reduction of the overall lens thickness. This is especially noticeable at the edges of the lenses and may reduce them enough to make them viable in a rimless style. And because less material is being used to form your prescription, high index plastic lenses weigh less than an identical prescription cut of standard plastic or glass.

Seek the advice of your optometrist or eye-wear manufacturer; they’ll be able to read your prescription and tell you if your lenses can be mounted in rimless or semi-rimless styles.
