Deep Research
The story behind Parafina’s education project in Paraguay
- The project traces back to 2014 when founders Samuel Soria and Alfonso de Luján personally befriended children in a Paraguayan village and witnessed the barriers to schooling — this origin story, grounded in direct relationship rather than a consultant’s recommendation, gives the commitment an authenticity that resonates with buyers looking beyond a logo.
- The project is anchored at Escuela José María Bogarín LaSalle, a school in the Fátima neighborhood of Asunción that serves 605 students from kindergarten through ninth grade and sits in a low-income area where most homes lack formal title deeds — each purchase supports education in a deeply rooted, identifiable community rather than a generic fund.
- Since 2019, a dedicated support team — psychologist, psychopedagogist, and teacher — has provided individual therapy to 205 children and school support to 70 students, bridging mental health and learning gaps that can otherwise undermine academic progress; this psychosocial layer, funded by the same 5% of sales, elevates the initiative from paying fees to actively removing barriers to learning.
- Since 2014, Parafina has financed 485 full-coverage scholarships that include monthly fees, school supplies, and tuition, a cumulative figure that converts the 5% of each $45 pair into a sustained educational pipeline rather than a one-off donation — the scale signals that the brand’s social commitment is a structural operating principle, not a marketing add-on.
- Parafina achieved B Corp certification in 2019 and was named Best For The World™ in the Community category in 2022, meaning its social and environmental performance has been independently verified against the rigorous B Impact Assessment — this external stamp signals that the 5% education commitment is part of a larger, audited framework of accountability.
- Currently, the project maintains 180 active scholarships, and each sponsored child receives not only tuition but also psychological help, a daily hot meal, and school supplies — a holistic support package that transforms the scholarship from a financial transaction into a comprehensive safety net, directly fueled by the 5% on every pair.
What recycled HDPE means for durability and feel
- Starting life as containers for aggressive detergents, the recycled HDPE frame naturally shrugs off skin oils, sunscreen, and frequent alcohol-based cleanings — there's no risk of the material hazing or weakening from the very chemicals it was originally designed to hold.
- With a specific gravity of ~0.96, HDPE weighs about 25% less than cellulose acetate (1.28) and 10% less than TR-90 nylon (1.05), so the Sena's 43-25-148 mm frame comes in well under 20 grams — light enough to forget you're wearing them during hours of reading or screen time.
How these glasses compare to other sustainable options
- Sena ships with a rigid recycled-plastic case, soft case, cleaning cloth, designer pen, and a plantable seed pencil—a far richer unboxing than the single recycled-material slip case included with similarly priced eco-readers like Remaldi's Bonola Juniper.
- Sena's polycarbonate lenses are topped with an anti-reflective coating that reduces screen reflections and eye strain, an enhancement not listed for competing budget eco readers like Remaldi's Bonola Juniper and Faroe Blue, where lenses are described simply as 'quality reading lenses.'
- Sena lenses block up to 30% of blue light from digital screens, a feature that most budget eco reading glasses (like Remaldi's £16 Bonola Juniper and £18 Faroe Blue) do not advertise, giving Sena an edge as a two-in-one reader and computer glasses.
- Every Sena purchase includes a 5% donation to the Parafina Social Project, which funds education for children in Paraguay—a charitable tie-in that gives the glasses a purpose-driven narrative beyond their eco-materials.
- The frames are explicitly made from 100% recycled HDPE sourced from detergent, shampoo, and similar containers—a granular origin story that contrasts with the generic 'recycled RPC material' or 'recycled polycarbonate' language used by competitors like Remaldi's Bonola and Faroe.
- Covry and Proof Eyewear charge $105+ and $215 respectively for sustainable blue light glasses with plant-based or wood frames, while Parafina Sena offers a comparable eco-narrative and blue light protection at $45 CAD—achieving its lower price point by using recycled HDPE rather than acetate or wood.

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.

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.

Q&A
2 answered- Do these glasses provide UV protection, or are they strictly designed for indoor blue light blocking?
- These glasses are primarily designed for indoor blue light blocking, but the polycarbonate lenses inherently provide UV protection as well—polycarbonate naturally blocks 100% of UV rays.
- Are the lenses scratch-resistant, and how should they be cleaned to avoid damage?
- Polycarbonate lenses are impact-resistant and fairly scratch-resistant, but they are not scratch-proof. To avoid damage, clean them with a microfiber cloth (included) and lens cleaner or mild soap and water; avoid paper towels or abrasive materials.
