Heavy eyes and diziness. Of anxiety too?

For last few weeks i am having diziness and heavy eyes. Dizziness happens while sitting on computer and concentrating. Sometimes very slight vertigo like feeling( diziness is right word to describe by the way) i visited opthalmologist and my eyes were told okay. They advised conversion exercise. Later on i visited an ENT and he also said my ears are clean and okay. However previously a month ago i had a mid ear infection and that time the ent doc advised me to take a nose spray and steam regularly. But now when im having heavy eyes and diziness, my ears are clean and ok. I was diagnosed with anxiety in 2012 when my dad passed away. Is it bcz of anxiety too ? When i change my heads position the vertigo feeling does not come so we had to rule out labrynthitis. But it could be minieres disease. ENT doctor could not diagnosed it. Its not bothering me much bu the way and in the mornings i am all okay and feeling great. The problem appears later in the day when i start working
