I've often noticed that my distance vision is slightly blurred only during stormy weather. Could this be caused by low air pressure (it seems like pressure would be equalized within and -out the eyeball faster than the barometric pressure outside changes !?) or refractive index of the air?

What does Air Pressure mean?
Air pressure is the amount of air pushing down on you over a given area. In weather reports it is generally based on 14.7 lb/in2 as "normal". It rises or lowers with high or low systems and predicts changes in weather such as storms. many household barometers measure air pressure and have an indicator that points to weather conditions such as Fair, Storm, or Change as the pressure changes.
How does the rib cage function during gas exchange in rat?
The rib cage expands, causing a negative pressure change in the abdominal cavity, which can only be relieved by letting air in the lungs. Exhaling is the opposite: the rib cage contracts, causing a positive pressure change, which is relieved by expelling air from the lungs.
What happens if the air pressure in the throat and outside is less than the air pressure in your middle ear when you swallow?
if the aie pressure in the throat and outside the body is less than the air pressure in your middle ear when you swallow the air pressure in your middle ear reaches the same pressure as the air in your throat and outside , and the eardrum moves quickly back-or'pops' into place
What happens to the air pressure in your chest cavity when you diaphragm relaxes?
OK, do you mean when the airway is open? If open, a slight decrease in pressure momentarily. If closed, a larger decrease in pressure.
Pressure inside human body?
The air pressure inside a human body is roughly equivalent to the pressure of the atmosphere. Normal air pressure is about 13.7 pounds per square inch at sea level.
A change in can bring about a change in air pressure?
if the dna sequence of a gene was tacttaccgagctagact then what kind of mutation has occured This has nothing to do with the question of air pressure. Either a change of temperature or a change of volume can affect air pressure, according to Boyle's Law of Gases. Increasing temperature=increased air pressure Decreased volume=increased air pressure The reverse is also true. Decreased temperature=decreased air pressure Increased volume=decreased air pressure
How does no gravity affect no oxygen?
the air pressure is different where if the gravity substances were to change it will be normal
What are some elements that change air pressure?
temperature (heat), volume, water vapor, and altitude (how high or low it is) all affect air pressure
Why does temperature affect the air pressure?
Air temperature and air pressure are inversely proportional. As temperature increases, air pressure decreases. This is best demonstrated in an enclosed vessel.
How does pressure affect the air?
Atmospheric pressure systems are made of air.
How does altitude affect density and air pressure?
Altitude has a large affect on the air pressure and air density. Air density reduces with altitude and air pressure reduces with altitude as well.
What are the factors affect air pressure?
Three factors that affect air pressure are temperature, altitude, and water vapor.
Does air pressure affect gravity?
Gravity is a function of mass and distance. So, no air pressure does not affect gravity.
How does the air affect pressure systems?
Atmospheric pressure systems are made of air.
How does air pressure affect the environment please answer?
Air pressure affect the environment as by creating a type of force and just like liquid creates a pressure .
How does air pressure affect air movement?
Air pressure affects air movement because air moves from high pressure to low pressure. The air pressure pushes or will press the air around.
What four things affect pressure?
Change in volume - container getting bigger or smaller with same amount of air; Change in temperature - air gets hotter or colder causing it to expand or contract; Change in density - air is pumped into or out of a fixed container.
