So, you’ve just had an eye exam and your optometrist or ophthalmologist has given you an eyeglass prescription. He or she probably mentioned that you are nearsighted or farsighted, or perhaps that you have astigmatism. (If that’s not the case, and you need to see an eye doctor, click here to find one near you.) But what do all those numbers on your eyeglass prescription mean? And what about all those abbreviated terms, such as OD, OS, SPH and CYL?
What OD And OS Mean
The first step to understanding your eyeglass prescription is knowing what “OD” and OS” mean. They are abbreviations for oculus dexter and oculus sinister, which are Latin terms for right eye and left eye.
Your eyeglass prescription also may have a column labeled “OU.” This is the abbreviation for the Latin term oculus uterque, which means “both eyes.”
Prescriptions written for eyeglasses, contact lenses and eye medicines, some doctors and clinics have opted to modernize their prescriptions and use RE (right eye) and LE (left eye) instead of OD and OS.
On your eyeglasses prescription, the information for your right eye (OD) comes before the information for your left eye (OS). Eye doctors write prescriptions this way because when they face you, they see your right eye on their left (first) and your left eye on their right (second).

Sphere (SPH). This indicates the amount of lens power, measured in diopters (D), prescribed to correct nearsightedness or farsightedness. If the number appearing under this heading has a minus sign (–), you are nearsighted; if the number has a plus sign (+) or is not preceded by a plus sign or a minus sign, you are farsighted.
The term “sphere” means that the correction for nearsightedness or farsightedness is “spherical,” or equal in all meridians of the eye.
Cylinder (CYL). This indicates the amount of lens power for astigmatism. If nothing appears in this column, either you have no astigmatism, or your astigmatism is so slight that it is not really necessary to correct it with your eyeglass lenses.
The term “cylinder” means that this lens power added to correct astigmatism is not spherical, but instead is shaped so one meridian has no added curvature, and the meridian perpendicular to this “no added power” meridian contains the maximum power and lens curvature to correct astigmatism.
The number in the cylinder column may be preceded with a minus sign (for the correction of nearsighted astigmatism) or a plus sign (for farsighted astigmatism). Cylinder power always follows sphere power in an eyeglass prescription.

Meridians of the eye are determined by superimposing a protractor scale on the eye’s front surface. The 90-degree meridian is the vertical meridian of the eye, and the 180-degree meridian is the horizontal meridian. Axis. This describes the lens meridian that contains no cylinder power to correct astigmatism. The axis is defined with a number from 1 to 180. The number 90 corresponds to the vertical meridian of the eye, and the number 180 corresponds to the horizontal meridian.
If an eyeglass prescription includes cylinder power, it also must include an axis value, which follows the cyl power and is preceded by an “x” when written freehand.
The axis is the lens meridian that is 90 degrees away from the meridian that contains the cylinder power.
Add. This is the added magnifying power applied to the bottom part of multifocal lenses to correct presbyopia.
Prism. This is the amount of prismatic power, measured in prism diopters (“p.d.” or a superscript triangle when written freehand), prescribed to compensate for eye alignment problems. Only a small percentage of eyeglass prescriptions include prism.
When present, the amount of prism is indicated in either metric or fractional English units (0.5 or ½, for example), and the direction of the prism is indicated by noting the relative position of its “base” or thickest edge. Four abbreviations are used for prism direction: BU = base up; BD = base down; BI = base in (toward the wearer’s nose); BO = base out (toward the wearer’s ear).
Sphere power, cylinder power and add power always appear in diopters. They are in decimal form and generally are written in quarter-diopter (0.25 D) increments. Axis values are whole numbers from 1 to 180 and signify only a meridional location, not a power. When prism diopters are indicated in decimal form, typically only one digit appears after the period.

In an attempt to cover quite a number of running projects and games, here are a few launches, news items, and announcements to pore over.
Akoha – Come play it forward! Self-labeled as a “social reality game”, Akoha is physical card-based game with ‘act-of-kindness’ missions to carry out on or with friends. You can get cards by buying decks, or by being given a card by someone who just completed a task. The visual explanation explains how players registered at akoha.com can see each card’s history of good deeds (including video blogs, testimonies, etc), who’s done what, when and where, and players can also earn karma points for carrying out these tasks. With enough karma you can begin creating other missions for people to carry out. Akoha is currently in a beta testing phase, but it’s a “big, bold and crazy kind of idea”, and it’s Canadian!
I knew without a doubt that it was the same presence I had felt in the garden as a child and things were okay. – Rifqa Bary
Roman Catholic mysticism, long abhorred by Evangelicals and Protestants, is a form of “white magic” that basically mixes pagan witchcraft with Christianity, giving the outward appearance of being of God. Often times it is reported that contact has been made with benevolent entities, who claim to be Jesus, Mary, or some other angel of light, when in reality, these beings are of darkness. The Bible strictly forbids any form of contact with the spirit world, outside of direct prayer to God alone, and God’s specific revelation through Scripture alone. (Lev 19:31, etc.) However, mystical experiences are becoming more and more popular as we approach the Lord Jesus’ inevitable return.
We had a bit of a party on our hands at the brewery this past Friday. Not in the Tasting Room, though — that’s always a good time — instead, it was over at HQ. The guest list included Ben Menk from Farm and Fisherman restaurant in Cherry Hill, Shirl and John Formisano from Formisano Farms and Produce, Asst. NJ Secretary of Agriculture Al Murray, and NJ Secretary of Agriculture, Douglas Fisher.
There’s no way to shoot these lenses off the camera to see how they work without correction; they are intended to work with the camera as a complete system.
The XT-2 has a huge, live electronic finder with eye control, about 15 years ahead of LEICA’s plastic EVF on the M typ 240. Fuji is actually advancing the state-of-the-art in photography, while other brands are just sitting around selling the same old thing. This Fuji actually has dials and a control system that work together, not like the could-have-been-great dials on the Nikon Df.
The X-T2 focuses super fast, and it’s super sharp, and unlike a real SLR or rangefinder camera, the XT-2’s closed-loop mirror less auto-focus system ensures that focus is dead-nuts perfect every time.
When you use the Fuji, you’ll see how they’ve actually been thinking about how to rethink what a camera should be and add new features that help us get the shot, as opposed to throwing more junk features in our way to help sell more cameras.
The X-T2 has a very different sensor from other brands, and its images look very different. It has no anti-alias filter, so the results are much sharper than from most other cameras.
The X-T2 just shoots, and the results are always super-sharp and well exposed better than I get from DSLRs, whose exposure and focus aren’t always dead-on as they are with the X-T2.
The X-T2 has real exposure mode switches. Nikon and Canon don’t any more. Better yet, the Fuji, just like Contax, changes its exposure mode automatically as you turn the shutter and/or aperture rings to A when you want them to set themselves. Set both to A for Professional (formerly Program) exposure mode. Done.
