SAFE&SOUND—8Hrs Anti Fog Spray For Spectacles, 2—in—1 Unique Benefits,Fog free solution+Glass cleaner spray— Anti fog Spray for Spectacles,Car Windshield,Bike Helmet Delivers Upto 8Hrs-100ml

I am a spectacles user and during this Covid era, I was having problems with wearing the glasses along with the face mask. My glasses would fog up due to breathing out into the mask.I would feel disoriented at times due to this and actually started removing my glasses while walking in the street.Then an acquaintance told me about this spray. I immediately got one from Amazon and am using it regularly. Everyday during bath, I wash and rinse my glasses with soapy water and then let it dry. Then i spray Safe and Sound once on each lens (inside and outside) and keep it aside for drying. Then after a couple of minutes i wipe the lenses softly with a tissue. I am happy with this product. It really works. Now I bring it to my workplace also to treat the reading glasses as well. A colleague also used it and she has also ordered one. Good product.

Product not easy to use. When applied, doesn't dry easily. Not suitable for spectacles, as it leaves specks on it. Dont know how the product was intended to be used. Instructions not clear. Maybe a live demo video on youtube will be helpful for those who bought this and unable to see its effectiveness.

Not effective in humid weather

Its easy to use but didn't help much with what it was meant to do. Not worth it .

Does as expected, but don't presume it'll last 8 hours. More like 3 to 4 hours in actual test. Needs reapplication for continuous fog-free performance. New users, please do not apply on the outside of your eyewear or helmet unless you want bugs and dirt sticking to lens. Seriously, it can do the opposite of what you want and will blind you. Do apply liberal coat on the inside of your lens and let it dry for 5 minutes. Then, gently - super delicately massage the film with a soft cloth to rub the excess. Let the remaining dry in the air. Don't expect crystal clear visibility after application as you can't rub the film completely and yet have fog free performance. You can clearly see a slight coat after try but live with it like you live with glasses. It's a small inconvenience you can ignore. Rest of the product seems to hold good to its promise. Will buy again and also recommend to another.

The sprayed liquid has to be wiped off and in wiping, the lenses get further smudged. Tried using it twice and had to then discard the product. Hope that manufacturer works on a better formula that doesn’t need wiping. Or create a gel that can be spread by hand or microfiber cloth.

Been using this product for a week now, have found it really effective for my spectacles, such that I carry it in my bag pack, the other day me and my friends were on a trip and the windshield was fogging up and I was able to save the day with the help of Anti-fog, really useful totally recommend it, wish there was a more travel friendly version but all in all fulfills what it promises.

This product cost me 2 branded premium frames worth Rs8000/- in total. The alcohol content in the product is too high that it cracks the plastic frames in mere 20 seconds. And it's not just a minor scratch, nope!! It's a deep crack. I saw one of my frames literally cracking open!! I couldn't believe it's the solution and blamed it on the brand as a defect, but when it happened the second time, I was sure it's this solution.It works just fine on metal frames and keeps them from fogging for 6-8 hours, but beware! It's not safe to use this product regularly.
