When I get the first pair of my eyeglasses, I often wipe the lenses with a piece of soft cloth. The lenses of my eyeglasses are very clean. But later, I won't clean my lenses that often. Actually if I don't touch my glasses with my hand, they won't go dirty that easily. So I suggest you not to touch your eyeglasses with your hands from time to time. You can take off them and spray some cleaner on the lenses and wipe it with a piece of clean soft cloth.
Just clean the lenses and frame with a piece of clean soft cloth. Dude, they don't need special care. After taking off them when you don't need them, you can clean them and put them into the eyeglasses case. You can also buy a bottle of solution in any optical shop. It can help clean the lenses if there is some grease on the lenses or frames caused by sweat.
I am a current glasses user. I seldom spend too much time on cleaning my eyeglasses. There is a piece of soft clean cloth and a case gives away by the optical when I bought my glasses. I often use them to clean my eyeglasses and protect my glasses. I think that's enough. But I will bring my glasses back to the optical shop where I bought them from every half a year. The optician will clean my glasses with some special kind of clean machine. This is totally free.
Some people will dip their glasses into soap water because this will help clean the grease on the frame and lenses. But I don't suggest you to do that. you can rinse your eyeglasses with soap water for a while and then rinse them with clean tap water. And this kind of way is only recommended when your glasses are very dirty. The metal on your frame will have chemical reaction with soap water that's why you can't dip them in soap water for a long time.
