Ophthalmology & Optometry - Optical measurements

Expert: Dr Anand Shroff, MD, FICS - 11/11/2009

Question
I would like to order glasses online but they required information for OD-SPH, OD-CYL, OD-AXIS, OD-ADD on both eyes. I went to a local eye doctor and asked what to fill in for each and received a paper saying Right: -350 DS and Left: -350 DS. What does this mean?

Answer
OD is the right eye and OS is the left eye
the -3.5 is the power you have ...DS is the Dioptres (measurement of the power like cm, inch etc)

However, from what you have written cannot be sure if this is purely spherical (SPH) or has a cylindrical error (Cyl), if a cylindrical error, then usually has an axis like 10 degrees etc.

You may be having a simple spherical power of -3.5 D in both eyes, but this needs to be confirmed from your treating optometrist.

It may be better for you to check this rather than guesswork as it may cost some!
