The BEST!
I got a sample of UltraVue Gel Lens Cleaner and a soft cloth when I made a purchase of alcohol for science labs.  NOTHING I've used in the past has cleaned my eye glasses as crystal-clear and residue-free as UltraVue Gel!  Unfortunately when I finished the UltraVue Gel I purchased another lens cleaner by Zeiss and was sorely disappointed, as the Zeiss smells terribly, is rather thin and drips off the glasses.  The UltraVue Gel Lens Cleaner sprays perfectly with a narrower spray, landing only on the lens and not all over the desk/floor, then being a gel, UltraVue remains on the glasses and does not drip, until you wipe it with the cloth.  There is no smell at all to UltraVue Gel - I have many allergies to fragrances - UltraVue has been the ideal product since it has no odor.  Folks have made nice comments about my eyes and my glasses lately - I think it is because UltraVue keeps my glasses so pristine and clear!  I recommend UltraVue Gel Lens Cleaner as a product worth the purchase.
