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

Hi! I have 25 years and I have an 0.50 astigmatism. I have a cylinder glasses prescription. Should I wear them or not?
I'm 43 and feeling eye strain lately. My prescription in both eyes: sphere +25, -.50 cylinder, od axis 85, os axis 105 with a +1.00 add. Will glasses help?
Translation: Od = right eye; os = left eye; sphere = basic power which is a + or - number; cyl = astigmatism power ; axis = the orientation of the cylinder; add = how much extra for near vision in bifocals; prism = prism power (not common) these are the basic numbers - there is no direct correspondence between these and the acuity (20/20 or so). Contact lens prescriptions are different. ...Read more

My eye prescription is -8 at the age of 22. It seems to have stabilized but what can I do to improve my eyesight?
I wear glasses (prescription) but only whn my eyes still constantly hurts in the sun watching tv etc vwey sensitive. Would you recommend contacts?
Depends: If your vision has changed since the last time you got glasses, you'll certainly want to be examined to get a new prescription. If you just want a different style frame/lens shape, the glasses providers can read your prescription from current glasses & adapt it to new frames /lenses of your choice. Still a good idea to have yearly eye exam to check for glaucoma, cataracts, macular degeneration…. ...Read more
