I feel embarrassed when people comment on my screen settings. I know this is ridiculous, please help me get over it.

You have a disability and the company should be making adjustments to help you so I would get back on to them about it.
I don't think you should be embarrassed about telling people that you have difficulties with your eyesight. You don't have to go into all the details about it, just say that you have an eye condition which means you need to have larger text on the screen to be able to read clearly.

How can they see your screen- just walking past or something? Have you tried a privacy screen like this: https://www.ebay.co.uk/itm/166023622485?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=LzGmWwRQc6&sssrc=4429486&ssuid=XhozZabkQo6&var=&widgett_ver=artemis&media=COPY

Could get this plus a screen behind you or move desks so they can't walk past the back of your chair

I understand that the software is really old, etc. But I don't understand why you are working with a normal computer screen. Thinking laterally.... can't you have a 42" TV screen type thing and use that as your monitor? Work should pay for it - this is a reasonable and not very expensive adaptation!

Op, maybe look into a screen magnifier. You can get them for phone, not sure about desktops.that might be a reasonable adjustment they could make.

It's hard OP when you get a diagnosis of anything. You want to hide away and pretend to be "normal". Your colleges don't need your medical history, but a little bit of context will stop the comments (unless your colleagues are all arses).

I've had crap eye sight my entire life. I have font on my screens big and ask others to make theirs big if I can't read it.

Usually I just make a passing comment about crap vision, followed up with I refuse to squint at screens, hence I've got no wrinkles!

After that if things are small I jokingly ask if they're trying to give me wrinkles.

I'd probably tell your coworkers I can look at a blur or I can read the screen and be helpful.

Oh that makes sense. That's the point at which you say, "apologies I can't read the text any smaller, do you want to wait or shall I email it over?".

That's not good enough. They should be making reasonable adjustments so that you can do your job. Or at least give you an office/office space where you're not overlooked.

I'm the same!! People make comme ts about me. I just give a jokey reply so.ething like ' call me Mr Magoo'
Actually ill have to update them cultural reference, the staff are getting g younger and will have no idea what I'm talking about!!

Your employer has a duty of care toward you to put in reasonable adjustments to help you see your work better - even if they say there isn't anything that would help. They are unlikely to bother doing the research to find out whether there is something that could or not. Your sight impairment will be covered under the equality act. They should also fund the cost of reasonable adjustments however it's worth checking on here too.

do you have a union?

I'm no expert but if you need screen adjustments to see becaues of a medical condition, I think your employers are legally obliged to make those reasonable adjustments.

I'd take some legal advice because forget about the comments, it's just not fair that you are having to do all this scrolling

Don’t be embarrassed, you have a health condition. Just tell them ‘I have an eye condition, I need my screen like this’

They are not making reasonable accommodation for your disability. Time to speak to your union and HR.

If anyone asks, say I am visually impaired and these setting work for me.

Could you try saying "I can make the text smaller but it will also make my output slower - which would you prefer?"

Get a LARGE text sign for your desk that says NOT All Disabilities are Visible.

If they are making you repeatedly feel like your medical condition annoys them that's a THEM issue not a you issue at all and their behaviour is discrimination in the workplace. You are making adjustments to help you work with outdated systems, you are not a hindrance to them.

Why do they sound annoyed? It's your screen.

If you are in UK
What does access for work?

I have a huge laptop because of my poor eyesight. It's so big it shouldn't really qualify as a laptop. People comment but I just say I have poor eyesight and need a big screen.

Have you tried a screen magnifier by the way? Also, maybe speak to the RNIB, they are incredibly helpful and supportive,they may have some suggestions to help.

I am sorry you are going through this. Two practical suggestions for you. Many years ago a colleague in a similar position had a large magnifying glass set up in front of his monitor. Would something like that work for you? Alternatively do you have a meeting room with a projector in your office? We use one for training so many people can look at the screen at once. My colleague with eyesight issues sat right at the front.

Embarrassed about what? Just saY “I can’t see the small text, I have to use reasonable adjustments.”

Honestly I'd just tell them. You don't have to into the ins and outs of it. Dh is pretty deaf, even with his hearing aids in he still struggles. He just says something like sorry mate, I'm deaf as a post, you'll have to speak up or sorry if I'm shouting, I'm deaf etc. Everyone understands and it's no big deal.

Having a disability is nothing to be ashamed of or embarrassed about. Most people at some point have something up with them whether it's dodgy eyes, a dodgy hip, bad back etc

You have a right to reasonable adjustments in the workplace. Ask HR about this if your line manager is being useless.

Regarding the comments, I would just make it known in a polite manner that you have issues with your eyes and don't need the help thanks. Just rinse and repeat. I know it's a pain but say it again and again until it sticks or just smile and ignore.
