My prescription eye-wear broke this summer presenting us with a sudden, though not entirely unexpected, expense. Fortunately our budget includes a monthly savings allowance for optometry needs and, since I bought the new eye-wear from a wholesaler, we had the cost covered. Even so, there was little left for extras. Lens cleaner was easily dismissed – I haven’t bought that in years.
The last three cleansers I purchased failed. Two were opticians’ in-house brands and the other was a commercial brand. Two left multi-coloured smears, like gasoline-slicks, on the lenses and the other worked but was outrageously expensive.
That’s when I began making my own, though opticians cautioned against using “other” cleaners. Anything but their brand or specially formulated commercial products “could ruin lenses or their coatings.” This up-sell worked on me…twice. But after paying good money for smeared results I realized clean dishwater worked better.
Hubby complains my purse holds “everything but the kitchen sink” so clearly dishwater isn’t always accessible. ; ) I searched for a more portable formula and found one which used sudsy ammonia. But, that seemed too harsh a chemical and, ever cautious, I was reluctant to risk the possibility of it pitting the lenses or stripping their coating. Another recipe used castile soap but I haven’t (yet) found any. A common recipe uses a high proportion of rubbing alcohol but that makes a toxic solution for a child or pet. After a little more research, the recipe I created is a simple, mild, and effective one:
- 1 teaspoon of vinegar
- ½ cup filtered water
- 2-3 drops dish soap
- Mix these ingredients together in a well-cleaned spray bottle.
A spritz of this solution on each lens, then a light polish with a clean, soft cloth and eye-wear glistens. No harsh chemicals, no streaks, no smears, no gasoline-slick rainbows. Both the vinegar and dish soap have antiseptic qualities, and the solution has little (if any) toxicity. It’s also proven to be gentle on lenses and coatings. Total cost (using wholesale-priced vinegar and dish soap): less than a penny for 4 ounces of cleaner, approximately a 4-month supply for me.
I admit, after spending several hundred dollars on prescription eye-wear, it’s comparatively small relief to avoid buying lens cleaner. But, I begrudge spending money on products that don’t work well or are excessively expensive. This simple recipe not only works, it’s far more economical, and that value increases over the long term by maintaining a necessary investment in optimal condition.
