Product Insights
Parafina's Sena Rectangular Reading Glasses offer a lightweight (under 20g), eco-friendly frame made from recycled HDPE that funds scholarships in Paraguay. They block up to 30% of blue light and provide anti-reflective coating and UV protection, but the amber tint distorts colors and the narrow fit suits only small-to-medium faces, with wide-headed buyers reporting tightness. The $45 CAD bundle includes a rigid case, soft pouch, cloth, pen, and plantable seed pencil, delivering premium accessories and social impact at a value compared to higher-priced brands.

Super cute readers, cool packaging
Love that these are recycled, and they come with a box that is actually useful. The glasses themselves are really cute with nice colours. They fit well and don’t feel cheap.

J'ai 3 paires de celles-ci dans différentes couleurs et j'adore. Aussi, la force de la lunette commandée est bonne.
Really nice!
I've never bought glasses online, but these suit me very well. I got the brownish frames with specs of teal. They're light, and it's my first pair of reading glasses, so I got the 1.0, and they definitely make a difference with tiny print, such as ingredient lists on packages.

Great quality, love the blue tortoise shell frame color. Very classy and blue light blocking is amazing. Great readers, would buy again.

Parafina Reading Glasses
So glad that Simons carries a line of recycled plastic glasses - really all glasses should be to this standard these days. Found the glasses very comfortable, and recieved lots of compliments. Only 4 stars because a bit light on construction, but still much better than any similarly priced readers I have had previously. Buying another pair for home.
