What does my glasses script mean? OD-SPH-850 CYL+150 axis155 OS- SPH575 CYL+200 axis35 add OD+275 OS+275?
You have presbyopic myopic astigmatism. In laymans terms you have a high degree of nearsightedness, moderate amount of astigmatism(distortion) and need a strong bifocal (consistant with someone age 60 or more).
Do I need glasses if my vision is OD +0.75 Sph and OS Sph +0.75, Cyl -0.25, Axis 023?
wearing/not wearing glasses doesn't "fix" or "hurt" your eyes anyhow. you would see better with glasses but if you are satisfied with your vision, if you feel you don't need to see better then dont bother and save the money
What does SPH mean for eye exams?
SPH is the sphere, or the amount of magnification/demagnification your eye needs to see properly. If you have a positive number, the lens will help with closer images, and a negative number will help with distance images. CYL is the cylinder. What that is is a section of the lens that is a different strength that the main prescription. What usually happens is your eye is not round; it's more football-shaped which distorts the way the light enters your eye, causing difficulty seeing. The cylinder will lay in the opposite direction of how your eye leans, helping focus the light back how it's supposed to enter your eye. AXIS is the degree line, from 0 to 180, that the cylinder should be oriented. Not all eyes have astigmatism so not all will have a CYL & AXIS. Some may just have a SPH.
Can anyone tell me what this means: od sph -300, cyl -125, axis 10 and os sph -300, cyl -225, axis 170?
The numbers specify the optical power of lenses. Those numbers specify lenses to correct myopia and astigmatism.
