Ever stared at your glasses and wondered why the tiny gaps between the frame and lenses still look grimy—even after you’ve wiped them down? Those hard-to-reach spots trap dirt, oil, and bacteria over time, and the only way to get them truly clean is to remove the lenses. But if you’ve ever hesitated to take your lenses out (afraid of breaking them or messing up the frame), we’ve got a simple, foolproof trick to make it easy!

You’ll only need two cheap, easy-to-find items:
- A fine embroidery needle (the thinner, the better—thin needles slide through small gaps without damaging your frame).
- A length of sewing thread (cotton or polyester works—avoid thick thread, which can get stuck).

First, look closely at the gap between your lens and frame: you’ll see a thin nylon cord (called a lens retaining cord) that holds the lens securely in the frame’s groove. This is what keeps your lens from falling out—and what we’ll gently move to release the lens.
Take your embroidery needle and push it through the gap between the lens and the retaining cord. Pick a spot where the gap is slightly wider (usually near the top or bottom of the lens) to avoid piercing the cord.
Once the needle is through the gap, pull it until the sewing thread follows. Now you should have both ends of the sewing thread on one side of the frame—this is your “tool” to slide the retaining cord out.
Hold both ends of the sewing thread together and pull slowly and steadily in one direction (either left or right). The sewing thread will guide the nylon retaining cord out of the frame’s groove—don’t yank or pull too hard, as this can stretch or break the cord.
Keep pulling until the retaining cord is loose from the lens—you’ll feel it “give” once it’s out of the groove.
Now the fun part: taking the lens out! Grab the lens by the edges (avoid touching the front or back—fingerprints are hard to clean) and pull it straight out, parallel to the frame. Do not twist, pry, or “pop” the lens—this can scratch the lens coating or warp the frame’s shape.
If the lens feels stuck, double-check that the retaining cord is fully loosened—never force it!
With both lenses out, you can finally get to those grimy spots!
Wash with a mild dish soap or pH-balanced body wash (avoid alcohol, ammonia, or harsh cleaners—these strip anti-glare or blue-light coatings). Use warm water and a soft microfiber cloth to gently rub away dirt, then rinse thoroughly.
Scrub the frame’s grooves, nose pads, and earpieces with a soft-bristle toothbrush (the same one you use for your glasses—just make sure it’s clean!). Pay extra attention to the areas where the retaining cord sits—this is where most dirt builds up.
After cleaning, air-dry both the lenses and frame completely (or pat dry with a lint-free cloth) before reinstalling. Wet lenses can slip in the frame or leave water spots.
Putting the lens back is just as easy as taking it out—follow these simple steps:
Place the lens back into the frame’s groove—make sure it’s aligned correctly (the top of the lens should match the top of the frame).
Thread your sewing thread through the nylon retaining cord again.
Gently pull the sewing thread to slide the retaining cord back into the frame’s groove, following the same path you used to remove it. Once the retaining cord is fully seated, tug the sewing thread to release it from the cord.
Give the frame a quick shake to make sure the lenses are secure—they shouldn’t wiggle or feel loose. If everything looks good, pull the sewing thread all the way out, and you’re finished!
Most people never remove their lenses—they just wipe the surface. But built-up grime can:
- Make your lenses look cloudy (even if they’re clean).
- Irritate your skin (dirt and bacteria on nose pads cause breakouts).
- Shorten your frame’s lifespan (grime weakens plastic over time).
With this simple needle-and-thread trick, you can deep clean your glasses in 10 minutes—no special tools, no risk of breaking anything.
Ready to give it a try? Grab your needle and thread, and say goodbye to grimy glasses for good. Your eyes (and your wallet—clean glasses last longer!) will thank you!
