The Sarah and Sahana are two of Lensmart's top three best sellers, and both are large, square, tortoiseshell frames for women rated 4.9/5 on the store. The differences are in the details: the Sarah is a lighter TR90 and metal frame with a bold black front and a narrow bridge, while the Sahana is a classic all-over acetate tortoiseshell with a much wider bridge. Here's how to pick.

The key differences
1. Material and look
The Sarah combines TR90, a light and flexible plastic, with metal hinges and temples. Its front is mostly black with a two-tone tortoiseshell strip along the top. The Sahana is acetate throughout, with Lensmart describing a brown, cream and amber tortoiseshell pattern, a more traditional look.
2. Bridge and fit
Both frames are 142 mm wide, but the bridge is very different: 15 mm on the Sarah versus 21 mm on the Sahana. A bridge that's too narrow can sit high or pinch; one that's too wide can slide down. Check the bridge number on glasses that already fit you.
The Sarah also has wider lenses (55 mm vs 52 mm), while the Sahana has slightly longer arms (145 mm vs 142 mm).
3. Weight
The Sarah weighs 26 g and the Sahana 30.6 g. Both are reasonable for large frames, but the Sarah will feel a little lighter on your nose over a long day.
4. Price
At the time of writing, the Sarah costs $14.95 and the Sahana $19.95, frame only. Lensmart's "50% off every 2nd frame" offer applies if you buy two frames.
A note on lens height
Lensmart's descriptions for both frames say the lens height is 51 mm, but the spec tables say 45 mm (Sarah) and 44 mm (Sahana). Lens height matters most for progressive and bifocal lenses, so if you need them, ask Lensmart to confirm before ordering.
Buying tips
Both frames are sold without lenses; Lensmart says prescription lenses start at $5. Orders over $69 ship free, US Standard Shipping takes 10–16 business days after processing, and there's a 365-day warranty for defects. Non-quality returns only get a partial refund, so check your measurements first.
