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.
The year is 2689. The surface is a scar of rust and radiation. Two factions—the fanatical Survivors and the mutant-breeding Series 9—have fought to a stalemate. But deep beneath the shattered ruins of Neo-Tokyo, a third force awakens. It is not human. It is not machine. It is — Viral Anomaly Mutation .
Its signature unit: the —a hovering chitinous horror that leeches energy from enemy structures and spits back crystallized shards of corrupted plasma. Bases that fall to VAM don’t just explode. They pulse , transforming into spawning pools of purple ooze, spreading like a cancerous shimmer across the wasteland. kknd vam
Here’s a short piece of creative text based on “KKND VAM,” interpreted as a futuristic, high-intensity concept (drawing from the KKND game series and “VAM” as an acronym for something volatile or powerful): The year is 2689
VAM doesn’t negotiate. It doesn’t take prisoners. It assimilates . But deep beneath the shattered ruins of Neo-Tokyo,
Born from a failed bio-weapon codenamed “Krush Kill ‘N’ Destroy - Variant Adaptive Malware,” VAM spreads like a digital plague through living tissue and combat hardware alike. One moment, a Survivor tank is firing at a Series 9 behemoth. The next, its pilot screams as the cockpit weeps black vines of biomechanical fury. The tank pivots, now fused flesh and steel, turning its cannon on former allies.
In the new war, the old enemies face a grim choice: unite against VAM, or be erased from history—your last scream repurposed as its battle cry.
