Question 1

what does cylindrical power mean?

Accepted Answer

Astigmatism: If the front of the eye or the internal lens is not a perfect sphere and is slightly oval, it may require special correction in one direction. This is referred to as cylindrical power necessary to correct the ovalness. It is also referred to as the astigmatism of the eye.

Question 2

what does -2.5 cylindrical lens power mean?

Accepted Answer

Astigmatism: This refers to an ovality of the optical focusing elements of the eye.  It is measured by the difference between the steeper and less curved axes and for the prescription mentioned about, that difference is 2.5 diopters which would be incorporated in a corrective lens.

Question 3

i have a cylindrical power of 2.5 in 2014 .now it was 3. why it get increased?will it be a problem?

Accepted Answer

Vision: AS the lens changes its shape or size there can be change in vision resulting i change in power .

Question 4

if my spherical eyesight no. is  -1.5 and cylinderical no. is 0.5, then what power lenses should i get?

Accepted Answer

Simple formula: Spherical equivalent=sphere+1/2(cylinder). The sphere is the first number written in a glasses prescription. The second number is the cylinder. The third number is the axis.  Keep track of your signs both positive and negative when you are adding or subtracting above. The axis plays no role in formula above. You need -1.25. Fun fact: circle of least confusion equals spherical equivalent.Google it.

Question 5

my child is having -6 cylindrical power she is only 5 years. what is the best remedy?

Accepted Answer

Hyperactivity: Some children are more hyperactive than others. The key is to differentiate what may be within normal range vs those who are in need for additional evaluation. One way is to see if the child is doing what is expected of her at this age e.g. Normal eating sleeping and listening to your commands and not getting into danger areas to get hurt or hurting others.

Question 6

i have -5.5 spherical and -.5 cylindrical power with axis 10, what should be my contact lens power?

Accepted Answer

Contact lens fitting: You really need to be properly fitted for contacts.  For contacts, you not only need the power, but you also need the diameter of the contact lens and a base curve. Both these two numbers describe the shape of the contact lens and you need to be evaluated to see which lens provides the best fit for your eyes. A poorly fitted contact lens may increase the risk for eye infections.

Question 7

cylindrical power -6.5 in both eyes, is this really bad?

Accepted Answer

This is : A large amount of astigmatism.  You should see a corneal specialist to evaluate your corneas for a ectatic disorder like keratoconus.

Question 8

cylindrical power of -.25 in both eyes..is this considered bad?

Accepted Answer

Astigmatism: This is a nearly negligible amount of astigmatism and should not be responsible for any significant problem with vision.

Question 9

how to reduce cylindrical axis power in eye?

Accepted Answer

Surgery: Surgery like LASIK or PRK will correct astigmatism which is what cylindrical axis power represents. Otherwise glasses or contacts will compensate for the vision defect.

Question 10

how i can reduce cylindrical, positive and negative power for eyes?

Accepted Answer

You can't: There is no "natural" way to correct your vision. Just glasses, contacts, or corneal surgery.
