OD is an abbreviation for the Latin term oculus dexter which means right eye. Notice that the right eye information is asked for first even though we typically read from left to right.
OS is an abbreviation of the Latin oculus sinister which means left eye. That will be referenced on the far right column of the prescription.
SPH is short for sphere. The sphere of your prescription indicates the power on the lenses that is needed to see clearly. A plus (+) symbol indicates the eyeglass wearer is farsighted. A minus (-) symbol indicates that the eyeglass wearer is nearsighted.
CYL is short for cylinder. The cylinder indicates the lens power necessary to correct astigmatism. If the column has no value (is blank), it indicates that the eyeglass wearer does not have astigmatism. If this is the case on your prescription, you can leave it blank when entering it in.
AXIS is a prescription will include an axis value for those with astigmatism. This number represents the angle of the lens that shouldn't feature a cylinder power to help correct your astigmatism.
ADD is short for "additional correction." This is where details about bifocals, multifocal lenses or progressive lenses would appear.

I understand you're looking for "Prajesh Jena geology notes PDF free download hot." However, I must clarify a few important points before providing a helpful response.
First, I cannot promote or facilitate unauthorized distribution of copyrighted educational materials. "Hot" in this context often implies leaked, pirated, or illegally shared content. Second, if Prajesh Jena is a specific educator or content creator, downloading their notes without permission or payment (if they are normally paid resources) would violate their intellectual property rights.

Ethical stance: If Prajesh Jena is an individual creator, downloading their paid or personal notes without permission is unfair.
