I have astigmatism. My perscription: OD -0.5 D Cyl ax 95 and OS -0.5 D Cyl ax 70. Can I safely wear -0.5 ordinary spherical contacts instead of toric?
My daughter's eye prescription is od -3.00 sphere +2.00 cylinder 110 aaxis and os -6.00 sphere +2.50 cylinder 30 axis what does this mean?
OD is right eye,: OS is left eye. The first #s. sphere, are negative, meaning she is nearsighted. The second #s (cylinder) is the amount of astigmatism that is present. Since astigmatism means the eye is focusing light at an angle, astigmatism comes with a rotation axis. The cylinder is rotated to this axis so that the light can be focused straight on. ...Read more

My prescription is right eye- Sph +1.75. Cyl -2.00 axis 104. Left eye- +.25. Cyl -.25. axis 115. Add +2.00. Can I get away without glasses??
Probably but: its important to check with your state DMV as to the minimum vision requirements for driving. In most states, if you are 20/40 or better without glasses, you are fine. Your left eye prescription is minimal. Otherwise, if you feel like you function well without glasses then don't bother. Be safe. ...Read more
I have a corrective lens prescription for myopia. How do I derive the intermediate (computer) distance from a D.V. prescription?
Add a little plus: In most cases the prescription will be for distance indicating some degree of minus power. To adjust for computer screen distance, add +1.25 to this power and that usually works. Note however, that the pupillary distance (the space between each eye) is set for distance viewing (usually 57-63 mm) and needs to be adjusted closer for viewing of a video screen. ...Read more
My eyeglass script is od: +1.25-2.00x150 , os: +1.50-2.50x90 with add power of +2.50. What would my script be for an intermediate RX with reading?
See below: +2.50=-2.00 x 150 right; +2.75=-2.50 x 90 left Add power is +1.25. This would give what I call 'computer glasses' with intermediate and near range. ...Read more

Can I be fitted for regular RGP lenses, rather than toric rgps? OD: -6.25 -1.00x015, OS: -6.00 -1.00 x 175
My doctor insists that I need toric RGPs..
Yes you can: I disagree with your doctor.Get a more detailed answer ›
No: This could easily be done with a standard lens material. High index is nicer because it is thinner and lighter, but more expensive. ...Read more
Mostly: Ortho k is a systemic of molding mildly myopic eyes to correct the vision by wearing a series of too flat hard lenses which push the center of the eye inwards. It is a tradeoff since to maintain any improvement, you have to wear a "keeper" lens at night. It was developed as a way to keep non-professionals like optometrists in the vision correction game. It reverses when you stop the lenses. ...Read more
Os +0.5x-0.5, od 0x-0.25 after lasik for myopia. Is left eye considered over corrected? Can definatley tell difference at close range.
Power designation: This is a term from optics indicating the light bending ability of the lens in question. The number is generated in the process of refraction in the ophthalmologists office, and then written on the prescription so the optical shop can make the lenses of the proper power. ...Read more
