How to Dispose of Eyeglasses
- 1Eyeglasses, sunglasses, and reading glasses feature multi-coated optical lenses and composite metal/acetate frames that cannot be recycled as plastic or glass.
- ✓They must be discarded in standard municipal trash bags or donated to non-profit vision charity programs for reuse.
How to Dispose (5 Steps)
- 1
1. Discard in standard trash bags: Throw the entire eyewear intact into a volume-rate municipal trash bag (Jongnyangje) without separating lenses.

2. Do not toss into plastic/glass recycling: Multi-layer anti-reflective chemical coatings on optical lenses and composite frame metals ruin industrial recycling lines.

3. Safe broken lens wrapping: If optical glass lenses are fractured, wrap the frame securely in 2–3 layers of newspaper or cardboard before disposal to protect sanitation workers.

4. Eyewear cases and microfiber cloths: Faux leather / fabric clamshell cases and microfiber cleaning cloths go into general trash, while rigid plastic cases go to plastic recycling.

5. Donate usable eyewear (Recommended): If frames and lenses are in functional condition, donate them to vision charity organizations (such as 'An-a-juseyo') or local optometry collection bins for developing communities.
Real-World Examples
Prescription vision eyeglasses (acetate/metal/rimless): Standard municipal volume-rate trash bag
Fashion sunglasses / polarized fishing sunglasses: Standard general household trash bag
Portable reading glasses / blue-light blocking glasses: Standard municipal general waste bag
Smart audio glasses / Bluetooth sunglasses: Contain lithium rechargeable batteries; small e-waste collection bin
Frequently Asked Questions
Q. Why are transparent plastic and glass optical lenses not recyclable in Korea?
A. Eyewear lenses are engineered from specialized high-index resin polymers (CR-39, polycarbonate) vacuum-coated with up to 10 chemical layers including UV barriers, anti-reflective coats, and hydrophobic finishes. These complex chemical coatings fail to melt in standard plastic/glass recycling plants and contaminate recycled polymers, necessitating disposal in general waste.
Q. Since metal frame rims are metal, can I pop the lenses out and recycle the frame in scrap metal?
A. No. Metal eyeglass frames are crafted from composite specialty alloys (titanium, monel, nickel silver) bonded with acetate temple tips, silicone nose pads, and micro screws. Due to their small micro size and mixed alloys, automated scrap sorting lines cannot process them; discard in general municipal trash bags.
Q. How can I donate old functional prescription glasses or sunglasses in Korea?
A. Undamaged eyeglasses and sunglasses can be donated via mail to non-profit vision charities (such as 'An-a-juseyo') or dropped into optical donation boxes at participating optometry centers. Donated pairs are cleaned, measured for prescription power, and redistributed to underserved communities in developing nations.
