Yes,it is normal to feel uncomfortable and blurry as you are a first user!Because your eyes neeed time to adjust it.Maybe three days later you will have no unusual feelings.But make sure that you use it in the right way !Two notices:First,make sure you put them in the right place,not upside down.When you put the lense on your finger it looks like a small bowel,which presents you using it in the very right way, or you are wrong.Second,donot put the right lense in your left eye.For that if one of your eye has some inflammation ,the other one will be infected by the lense!
As you are a new user ,I am going to give you some proposals.You should wear it as what your doctor told you.Such as how long you can take it per day/week.And wearing contact Lenses makes eyes tired,you can buy some eye drops or an eyeshade for laxation.
