(More customer reviews)Lens cleaner is something I use every day due to the fact that I have approximately $550 worth of eyeglasses perched on my nose. With age comes more and more expensive glasses - I'm up to "high refractive index" lens (to avoid the coke-bottle lens syndrome), progressives (to avoid bi- and tri-focal lines), transition (to darken outside), non-scratch, anti-reflective (cut glare), titanium frames (lightweight). With all this technology perched on my nose, I understandably want to treat these marvels of innovation with care and avoid scratches and damage. To that end, I've used "anti-reflective-coating-safe" cleaners and microfiber cloths for years.
Purosol Molecular Lens Cleaner is impressive...and different from other cleaners. When you first spray it on a lens, you know you're working with a different cleaner from those you pick up at the local vision center. I was surprised to see the spray bead up on the lens; other cleaners may foam slightly and there is evidence of surfactants (the other sprays spread across the lens with no beading). This beading of the Purosol had me concerned at first (no solvent effect of breaking surface tension), but not to worry. The product insert states "Purosol's solvent-free formula used the latest in green chemistry to break the molecular bonds that dust, dirt and grime use to adhere to the lens" and it works beautifully. I ran several tests where, after an active day, and plenty of dust, cooking spatters or high pollen counts, I tried regular solvent-based cleaner on one lens, Purosol on the other. In every case, the Purosol lens was spotless with no streaks - every bit as clean as the other lens, but Purosol does it using, as the manufacturer states, "organic plant extracts instead of traditional solvents and contains no alcohol, ammonia or detergent and is free of silicone, graphite and glycerin. It is also streak-free and leaves an anti-static barrier which repels dust..." The bottle of Purosol comes with its own cleaning cloth and it seems to work better with the included cloth than the microfiber cloth my lenses came with.
With regards to the "dust repellent" claim - I don't know. For several days, I cleaned my lenses in the morning, again, one with Purosol and one with a solvent-based lens cleaner, then went about my daily business. By the end of the day, I would examine both lenses to see if I could detect any difference in the amount of fine dust particles on the lens - there wasn't a difference that I could detect with the naked (and very near-sighted) eye. Nevertheless, I wouldn't discount this cleaner for that reason. It does an extremely good job of getting the lenses spotless, leaves no streaks and does it without toxic chemicals. That makes it a winner in my book.
