• Why does the eyesight never get better?

  Simply speaking,it is just like our body.As we grow up,we can't go back to our original look.

• Should I get Mono vision contacts Or bifocal glasses?

  For your case,you have different prescriptions in your both eyes.Actually you don't need bifocals,single vision glasses are enough for you.You just need to have your eyes examined and get the prescription.The doctor will prescribed that kind of glasses for you.

• Can anyone tell me how do bifocal glasses work?

  Bifocal glasses have two different areas.The top area is used for seeing distant and the bottom area is used for viewing near.If you want to see distant objects, then hold your head up and look through the upper part of the lens.If you want to view near, like reading newspaper, then just look through the lower part of your lenses.Hope this helps you.

• Can I go for progressive lenses to see computer screen?

  Yes,you can.The progressive glasses are multifocal and enable you to see near,middle and far.But you may have difficulties in getting used to them at first.

• Why do people need bifocal glasses ?

  Bifocal glasses are usually needed by people over 40 who are nearsighted and have presbyopia at the same time.Due to the eye muscles degeneration as they old,their eyes lose the elasticity of seeing both near and far.So they need the bifocals to help correct their vision.

• Why does my vision get better when looking through a card with lots of holes in it?

  I don't know how to explain it but you may have the similar experience.When you look at something through a small hole,you will see more clearly.I think they are the same theory.

• Is it normal for a child to have bifocal lenses ?

  It is much less common for children to wear bifocals,but if you are nearsighted have problems in close work such as reading,you may need bifocals .

• How long will it take to get used to bifocal prescrition glasses?

  It is normal to have headache cuz your eyes are adjusting to get used to them.Generally it may take one week to get used.If the headache is acute,you need to visit your doctor.
