Do you also fell dizzy when you stand up after a moment of squatting? This is not a kind of eye problem but your body. It is called temporary insufficient blood supply. As the blood pressure is low when you squat, the blood can not reach our head, and the oxygen of red blood cell is not enough. Then it causes dizzy, eye blurry, tiredness and ears ringing. This often happens in the people suffer from anemia. And I'm one of these people. I suggest you eat food with vitamin Bs which you can get from fresh vegetables. Also, you can eat more beans, milk, animal innards and sea vegetable.
It is sounds like low blood pressure or Postural Hypotension. People with low blood pressure will feel dizzy and blurred vision when they stand up quickly or suddenly after lying or squatting position. If you want to be sure what 's really cause your blurred vision, you should be looked at by a doctor.
As you describe, you seem to suffer the orthostatic or postural hypotension. This is caused by low pressure. When you stand up too quickly from a seated or lying position, you may get blurred vision as well as dizzy head. People who suffer low pressure cannot bring enough blood to brain when they rise from a reclined position because their blood vessels are not constricting properly. Many reasons will lead low pressure such as pregnancy, heart problem, endocrine problem, dehydration, blood loss, severe infection, severe allergic reaction and lack of nutrients in your diet. You would better go to doctor for a check and then take the right treatment.
This is a temporary cerebral anoxia. But it is no problem. It is a common adverse reaction called anemia. Many people have blurry vision when you stand up or wake up. This kind of situation in medicine is called postural hypotension. In fact, it depends on your physical condition. If your body has a good circulation, you will not have blurry vision. Acupressure and massage techniques can work together to relieve tension at your tiger points and improve circulation throughout the body. Taking more exercise, getting enough sleep and having sufficient nutrition will improve the situation.
The blurry vision is a vision problem that results in lost sharpness, also fail to see tiny details. It can be caused by minor problems, such as myopia or wearing wrong glasses, or it's a symbol of aging, infection, trauma and others. It can begin suddenly and disappear quickly, such as when you wanna stand up, running. But you had better go to see eye doctor if you always have blurry vision, maybe it's a sign of serious disease.
Most situations like this are not serious, and you do not need worry about that too much. It is just a normal response to body adjustment. When you are sitting, your brain from the ground is low, and gravitational potential energy is low. Your heart can send blood to the brain just needing lower pressure. But when you stand up suddenly or stand up too fast, the brain from the ground distance increase, at the same time, the heart pressure could not change immediately, and the blood cannot be sent to your head at the same time, leading to dizzy and blurred vision. But you should also consider the possibility of low blood pressure. I suggest you go to the hospital to have a examination, just in case.
Once I also suffered from this condition. Then I surfed the Internet and found that this was caused by the insufficiency of blood supply at most time, because one may be in the unsteady mood when his/her hypertension or hypotension leads to the insufficient blood supply. At the moment, when you stand up after a long time's squat, your eyes may feel blurred, which we called blurred eyes. In fact, when this case happens, we need some home remedies. As we know, pig liver, vitamin A, B, C, E, fresh vegetables and chrysanthemum tea, etc which are good to eyes can be used to support your body's nutrition. Naturally, such morbidity will decrease in your life.
