Tinnitus is only a symptom of some underlying problem, and it is unlikely to have anything to do with the eyes at all. It is pretty much impossible that tinnitus would be either caused by an eye problem or would cause an eye problem. Your myopia has probably developed on its own, and the fact that it was discovered just after you developed tinnitus is only coincidence.
Myopia is most commonly managed by wearing spectacles or contact lenses of the appropriate strength. This is not really a cure or treatment, but for most people, this is enough. They are able to see quite normally using corrective lenses, and so no other intervention is necessary. Some people however recommended various eye exercises as a way to train the eyes to see properly again. As yet there is no clear scientific evidence to show that these exercises are effective. However, there is certainly no harm in trying them, and if you are interested, you should be able to find a lot of information on eye exercises online. A form of alternative medicine known as biofeedback also claims to be able to restore weak vision, but this too has not yet been proven. This is also not something that you can do on your own, so if you are interested, you will need to find a therapist who specializes in biofeedback.
Treatment of tinnitus will depend on the causes - in order to determine what is causing your tinnitus, you will have to visit a doctor. In very rare cases, the patient may be hearing real sounds that emanate from their ears, such as those made by muscle spasms or blood turbulence. This is known as objective tinnitus, and it can be quite dangerous. In most cases however, tinnitus is subjective - that is, the sounds are only perceived by the patient, but have no physical source. This is often an accompaniment to hearing loss, either as a result of physical trauma or excessively loud sounds over a long period of time. It is also thought that some cases of tinnitus may be due to nerve malfunctions.
As with any other health problem, treatment depends on the causes to at least some extent. If your doctor detects some underlying condition, then he or she will try to treat that condition, rather than treating the symptom of tinnitus. Usually, drugs and nutritional supplements are used to treat tinnitus, but in some cases surgery may be needed.
