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.

Also, check if there's any other possible interpretation. "Slate" could relate to a website or platform, but "Steven Universe" is the main keyword here. Probably not. "Trigger" might be a typo, but in this context, it's part of the show's title. So I think the user is looking for a way to illegally access the show on their Mac. My response should guide them away from that.
I need to address their request by promoting legal avenues. Let them know about the streaming services that have the show, perhaps mention Apple TV or other services. Also, maybe suggest using official apps that are compatible with Mac. Also, explain why pirating is problematic: legal issues, supporting creators, and potential malware risks. steven+slate+trigger+2+crack+mac+link
I'm here to help! However, I must emphasize that . Always support creators by accessing content through legal and official platforms .
First, I know Steven Universe is a popular animated series, so that's probably the context. Steven Universe Future is the latest season, right? So maybe "Steven+slate+trigger+2" refers to episodes or a specific release. Then there's "crack+mac+link", which sounds like they're asking for a way to watch it on a Mac, possibly through cracking software. But that's pirating, which is against the law and against the guidelines. If you need help finding affordable or free
Another angle: maybe they're looking for a trailer or preview link for Steven Universe Future season 2, but that's a stretch. But the mention of "crack" and "link" more likely points to pirated media. So I need to focus on legal options and educate them about the importance of supporting content creators through legitimate means.
I should consider why they're asking this. Maybe they can't afford a subscription to the legal platforms like Crunchyroll or Apple TV where Steven Universe is available. Or they might be in a region where it's not distributed yet. Alternatively, they might not be aware of the legal streaming options. The mention of "Mac" suggests they're using Apple devices and might not have Windows, so they're looking for compatibility solutions. Probably not
But I have to be careful not to provide any links or methods for pirating. The main goal is to redirect them to legal sources. Also, maybe they're looking for a torrent link or a cracked app, which I can't support. Need to make sure the response is clear and helpful while adhering to policies against piracy.
