Sph Cyl Axis
Eye glass measures: The sph is the sphere. This is the amount of nearsightedness or farsightedness, measured in units called diopter. Cyl is cylinder. This is the amount of astigmatism. Astigmatism is created when the cornea is not shaped evenly...Egg instead of a ping pong ball. There are other causes of astigmatism. The axis is an angle that indicates where the astigmatism is located. ...Read more
No: These numbers do not translate directly into a snellen acuity number (like 20/20). The degree of visual clarity is different than the eyeglass strength to achieve that clarity. ...Read more
What do you suggest if i could use sph, cyl and axis on my eye test to rate my vision strength and if yes how to rate my vision strength?
Yes: The best number to use is sphere (sph). If you are nearsighted or myopic the number has a minus sign in front of it. The higher the number, the worse your uncorrected vision is. If you are farsighted, the number is a plus sign and the same applies. The cyl stands for cylinder and is a measure of astigmatism. The higher the number, the worse the astigmatism ...Read more
5 yr daughter's eyesight prescription as follows:right (sph +/-, cyl +0.75,axis 90) left (sph+/-,cyl +0.75, axis 100) does she have to wear glasses?
Not really: This is a small prescription - simply some degree of astigmatism. This will produce an unnoticeable distortion at distance and none at near. She will find glasses to be a nuisance and they will not protect her vision nor improve it in any meaningful way. She may need to wear glasses in the future if things change, but not now. ...Read more
Spectacle power is RE -5.25 SPH -1.50 CYL 180 AXIS LE -5.50 SPH -1.50 CYL 180 AXIS. Age 32 What do you suggest for long term good health of my eye?
Annual exam: Because your eye is more nearsighted than average, you may have a longer eyeball which can put you at higher lifetime risk for retinal detachment. Have an annual dilated fundus exam to detect any weak spots in the retina. Sometimes the weak spots are repaired prophylactically. If you have warning signs of a dark curtain coming over the vision, flashes of light, or new floaters, go see the eye MD. ...Read more
How bad is my eyesight ?
Right eye - SPH-0,CYL- +0.25, AXIS-70,VISION-6/6
Left eye - SPH-0,CYL- +0.50, AXIS-85,VISION-6/6
Very good: These are extremely low powers that most would ignore and certainly not obtain corrective lenses for. They are in fact within the margins of error for LASIK correction which would be a bad option for you. You have excellent eyesight and I bet 6/6 (20/20) without any correction at all. ...Read more
What's my 20/X vision with a sphere of -5.25, a cyl of -0.50, 116 axis in OD/-5.50 sphere, cyl of -.25, axis of 074 OS?
Your prescription: Your eyeball is not a perfect mathematical sphere. As light comes from the outside it refracts through your lens to get back to your retina and thense to your brain. When the doc kept on putting different lenses in front of your eyes and asked you which was clearer he was experimenting with different lenses to get the "right" fit for your defective eyes. That's just a code. Review your physics! ...Read more
After 1 month after rd surgery my daughter refraction is as " sph -0.50 cyl -1.25 axis 175 va 6/7.5 . Is this good readings? Will it improve later?
Depends: What were her numbers prior to the surgery? Rd surgery with a 'scleral buckle' will have increased myopia (- power). After a month, assuming there is no more healing to do, then the vision generally stabilizes. But there may be some improvement. Check with the retinal surgeon who knows what was done and if the healing has finished. ...Read more
5 Axes: In the old DSM 4, which most still use, there are 5 Axes of mental health. Axis I is clinical syndroms, Axis II is personality disorder, Axis III is medical conditions that directly bear on current mental health functioning, Axis IV is environmental stressors, and Axis V is the Global Assessment of Functioning (GAF score) which is represented by numbers ranging from 1-100. ...Read moreSee 3 more doctor answers

No: Your contact lens prescription is determined with your contact lens fit. This is a process where your eyecare provider calculates the contact lens prescription and gives you one or more trial contact lenses. The vision and fit to your eyes is then measured and adjusted to get you the correct contact lens prescription. ...Read more
