Eye Glasses、women glasses and bifocal eyeglasses

Nowadays, the eye glasses,women glasses and bifocal eyeglasses are much popular and welcomed by hyperopia sufferers.But, while wearing
the bifocals and eye glasses, one need some time to adapt.We should sscientifically understand this adaptation process.At the beginning of wearing bifocal eyeglasses,
how can we view objects clearly at different distances?
• When looking objects at the distant, raise your head and see things at the eye level and form the top part of the lenses.
• Keep your head with a depression angle of 45 degrees, and look down through the lower lenses to see nearby objects clearly.
• Look through the middle part of the lenses to see the things in medium distance
• Each point form the top to the bottom in the transition zone corresponds each distance from the far to the near.
What kind of discomfort will appear when first wearing the women glasses?
• For example, slight dizziness,and swinging while you are walking,have to be beware of the vision when exercising or walking upstairs.
• The spatial sense takes change,It may cause an error when you try to make clear the distance that objects located at.
• When looking at the near objects, you need to convert your eyes, there might be uncomfortable.
• It is hard for you to see things clearly if you look things through the edge of the lenses.
Therefore,the geeners should rather turn their heads than their eyeballs.All in all, people had better use distant, near and intermediate zones to see objects.
