LOL, it is usual that you will find the products bought online do not suit you well, including your sunglasses. Here I will give your two possibilities; on one hand, if the frame of your sunglasses is plastic, you will ask the eye care professionals to use the professional device to adjust because only the eye care experts have the ability to do it. Of course, if you can not get the specialist, you can make it by yourself, just warm the frame and try to bend accordingly. Pls notice not too warm because it will melt. On the hand, if it is metal, there are some ways to make it. First, prepare NEEDLE NOSE PLIERS which will help you to correcting the frame of the sunglasses. Then lay down your loved sunglasses and try to adjust the temple piece, at the same time pls use the pliers and gently bend the screws on your nose piece. Hope you can make it.
If the sunglasses you buy from the online store are bigger for you which may often slid off your nose, you can just adjust the nose pad's distance. Such easy and direct way may make the sunglasses fit for you again. If you can't do this with no instrument, you could go to the eyeglasses store to ask for a favor.
It will make you feel so uncomfortable if you are wearing a pair of sunglasses which slid off from your eyes. So just take some measures to adjust them. To adjust your sunglasses, the first thing you should is to Put on your eyeglasses and, while looking in the mirror, identify precisely where the frame problems occur. Then you Tighten or replace the screws on your eyeglasses. Also, you should adjust the arms of the eyeglasses carefully, slowly and gently with your fingers or a pair of needle-nose pliers if necessary. Make a small, corrective bend in one arm at a time. Anyway you can surf the detail on the internet and just have a try. But if you have some problem which you can not solve them by yourself, youâ€™d better go and console it with a professional person.
