Quick answer
The FitOn Semi-Rimless Mirror Sunglasses are lighter than most full-rim sunglasses because they remove the lower frame, reducing overall weight while keeping the lens secure. This makes them a great choice if you want less pressure on your nose and ears.
Why weight matters for sunglasses
Heavier frames can cause discomfort during long wear, especially if you already wear prescription glasses underneath. A lighter frame reduces pressure points and makes it easier to forget you're wearing sunglasses.
Semi-rimless designs remove the bottom rim, which trims weight without sacrificing lens retention. Full-rim frames add material around the entire lens, making them slightly heavier but also more protective against impacts.
FitOn Semi-Rimless: a closer look
The FitOn Semi-Rimless Mirror Sunglasses combine a lightweight semi-rimless frame with Polarized TriLenium® 7 lenses. They are designed to fit over prescription eyewear, so they need to be both light and durable.
Because the lower rim is missing, the frame uses a nylon cord or tension mount to hold the lens in place. This keeps the weight down while still providing a secure fit for everyday use.
Semi-rimless vs full-rim trade-offs
- Weight: Semi-rimless frames are lighter because they have less material. Full-rim frames add weight from the complete frame surround.
- Durability: Full-rim frames protect the lens edge from impacts and scratches. Semi-rimless frames expose the lower lens edge, which may be more vulnerable to chipping if dropped. If you're rough on your sunglasses, a full-rim frame might last longer.
- Fit over prescription glasses: Both styles can fit over prescription eyewear, but the lighter semi-rimless design reduces the combined weight of two pairs of glasses on your face.
- Style: Semi-rimless frames offer a modern, open look that some people find more stylish. Full-rim frames are classic and provide a bolder frame color. Choose based on your personal style preference.
