Ive never had any luck with lens cleaner+microfiber cloth just smears the shit out of glasses. Here's my glasses cleaning process, I have had glasses my entire life and can't stand smearing even a little. My glasses coating has never been damaged from this though to cover my ass I will say do at your own risk.

1. Get paper towel, wet and spray with a liquid soap+water mix spray bottle I recommend Dr.bronner soap very environmentally friendly works well You can also use regular dish soap if that's all you have.
2. rub lenses with soapy paper towel really well on both sides. Get it soapy.
3. (MOST IMPORTANT PART TO PREVENT SMEAR) rinse soap off glasses and gently shake frames to get off all excess water that you can. Then grab 5-8 sheets of toilet paper, roll/fold into a square and fold tp square gently around lenses to wick remaining water. Do not rub tp into lenses, only gently press.
