I searched jisho and found `整える` but doing a google search for

> メガネを整える

came up with practically no results so I feel that it's not the appropriate
verb.

> メガネを繕う

came up with more hits, is that the right one?

I would probably say...

> ずり[落]{お}ちたメガネをかけ[直]{なお}す  
>  ずり落ちたメガネ（の位置）を[直]{なお}す  
>  ずり落ちたメガネを｛[上]{あ}げる / （指で）[押]{お}し上げる｝

Let me add a couple of phrases: 眼鏡を上げる、眼鏡を押し上げる、and 眼鏡クイッ. The first two are
fairly common.

The last one is a slangy (a bit otaku) phrase to describe the motion. Not
really useful in normal conversion, but you can use it as 眼鏡をクイッと(かけ)直す仕草 and
everyone should understand.
