Choosing Between the CHARLTON, MURPHY, and STEWART
If you're considering the Original Penguin CHARLTON, you're likely weighing a few other oval acetate frames in the same collection. Here's how the CHARLTON stacks up against its closest competitors.
CHARLTON vs. MURPHY: Size Matters
Both frames feature the same oval shape and acetate construction, but the MURPHY has a smaller 46mm lens width compared to the CHARLTON's 48mm. If you have a petite face or need the absolute smallest fit, the MURPHY might be your best choice. However, the CHARLTON's 48mm lens offers a bit more coverage and works well for small to medium faces. The CHARLTON is particularly popular with customers who have high prescriptions, as the slightly larger lens still minimizes edge thickness while providing better visual coverage. The MURPHY features a keyhole bridge for vintage styling, while the CHARLTON uses a standard bridge design.
CHARLTON vs. STEWART: Coverage and Comfort
The STEWART is nearly identical to the CHARLTON in design but offers a 49mm lens width—just 1mm larger. That small difference can matter if you prefer more coverage or have a medium to larger face. The STEWART's slightly larger lens provides better balance on wider faces, while the CHARLTON's 48mm size is ideal for those who want a more compact, tailored look. The CHARLTON has longer 145mm temples compared to the STEWART's 140mm, which may provide a better fit if you have a larger head. Both are excellent choices; your decision comes down to whether you want a slightly smaller or larger fit.
CHARLTON vs. SURPRISE: Style Alternatives
The SURPRISE is the CHARLTON's closest sibling, with a nearly identical 48mm lens width and similar oval shape. The main difference is the bridge width (20mm on the SURPRISE versus 19mm on the CHARLTON) and the color options. If you're drawn to the CHARLTON's fit but want different color choices—like Dark Denim or Mirage Grey—the SURPRISE is worth considering. The SURPRISE also has shorter 140mm temples, which some wearers find more comfortable.
Why Choose the CHARLTON?
The CHARLTON hits the sweet spot for small to medium faces. Its 48mm lens width is large enough to provide good coverage without overwhelming your features, yet small enough to minimize lens thickness for higher prescriptions. The 19mm bridge and 145mm temples offer a balanced, secure fit. If you're looking for a versatile oval frame that works for both casual and professional settings, the CHARLTON delivers classic style with everyday comfort.
