eye specs prescription meaning

Things you should take into account while your gets your eyes tests for lenses.

Eye spec prescription has following numbers :-

• Spherical
• Cylindrical
• Axis

When you are not able to see an object clearly you eyes will initially try to see clearly by changing the shape of corona to some extent. How if you are getting your specs made for the first time and you are prescribed sphere, clinder and axis numbers then your corona is never going to return to normal shape. In most of the cases there is possibility of your corona coming to original shape after start wearing the specs. Moreover you can never get the correct cylinder and axis numbers without you trying to wear sphere glasses for few minutes in both eyes and then adjusting the eys with cylinder and axis.

Eye coordination is the ability of both eyes to work together as a team. Each of your eyes sees a slightly different image. Your brain, through a process called fusion, blends these two images into one three-dimensional picture.

Then why your optometrist  puts more than 1 glass in each of the eye. He does it because he wants you to be visiting him every few years.

Unless both eyes co-ordinate you cannot find the AXIS and  cylinder numbers of the eye. You need to allow few minutes to few hours or few days to get the correct axis and cylinder numbers.

Cylinder number and axis number belongs to corona and not the eye lens which sits behind the iris.

But wearing a cylinder and axis numbers initially would mean that your eyes will remain strained for rest of life and will create problems with the lens behind the iris in next few years.

I am not an eye care professional. But then this seems to be common sense.

Let the debate on the above subject by joined by professionals as well. There is hardly any information regarding the above subject in the public domain.
