Ears pop and make a clicking sound when swallowing. slight dizziness and visual disturbances?

Not all related: The popping of the ears can be easily explained by Eustachian tube opening when you swallow. This is absolutely normal and you are just aware of a normal physiological activity. The slight dizziness is too non-specific to comment on. Both of these symptoms are probably not related to the visual disturbance. But certainly consult an eye physician for the latter problem.
