Does anyone have a DIY formula for cleaning coated eyeglass lenses? Is
Windex spray OK?

I would not use Windex on optical glass with coatings.

You can purchase specialized lens cleaning solutions; most
are a combination of distilled water, alcohol and a small
amount of soap/detergent.

I normally use the liquid soap that we have at out washbasin.
If the nose clips are really dirty, I'll use an old (soft)
toothbrush to clean them.

Then dry with a lint free cloth -- a CLEAN cotton handkerchief
is fine and a CLEAN microfiber cloth is better.

NEVER use paper-based products (like a regular tissue) on
optical glass or plastic. ALWAYS use tissues that are specifically
made/rated for optical glass or a clean lint-free cloth.

Trees and other plants produce phytolyths (micro crystals
of quartz, silica and other abrasives). These are carried
into the pulps and paper products and they will, over time,
scratch up a plastic or glass lens and any coatings on it.
