Well, according to your description, I can see that there is something wrong with your eyes. Because generally speaking, there would be no gas bubbles in our eyes and I believe we could regard it as a sign of something serious, such as a disease. So, sometimes the bubble would go away after two weeks or so, but we must pay due attention to our eyes from this moment. Just consult a doctor ok?
If the gas bubble is only a little in your eyes, it is not a serious problem. You just go to the hospital and let the doctor cure it for you. The doctor will prick the bubble for you. Then you should keep on using the eye drops to release your symptom. After a week, your eyes will get recovery. During this time, you'd better not eat the spicy food or other irritating food which will make your problems get serious.
