I friggin love that first day wearing new glasses and feeling like I've never seen clearly before. #nearsighted #astigmatism #glasses

How good is my camera lens?

This is a series of images of an artificial star as seen by a camera lens and digital camera. They range from one side of best focus, through focus, and onto the other side of focus.

I see two errors:

1. Collimation/alignment

2. Astigmatism (probably pinched optics...bad optomechanical support)

I will disassemble this lens to investigate further.

heads up for fellow astigmatic ppl whose eyes might struggle with dark mode-only websites, the Dark Reader browser plugin allows you to force websites into light mode too. you just need to go into the "more" tab and then check "static" in the "theme generating mode" section, otherwise you'll just be getting different types of dark mode instead.

it's not ideal since the plugin was made for people with the opposite of our problem, but it's still the best solution I could find. certainly better than nothing

My eyesight test did not go as well as expected. The astigmatism in one eye has become much worse.

I need to go back in a year rather than two, and I also have a few other issues that may be 'normal/stable' and due to improved detection, but will need monitoring.

New lenses are going to be expensive.

What is Astigmatism?🔥🔥#astigmatism

Let’s talk about dark mode and accessibility! There’s a myth that dark mode is good for accessibility, because it improves text readability. It's not always true.

@MiaWinter I guess it's safe to say it is normal here in the #Philippines since the early-90s. ^_^

Both with and without lenses.

I used to wear one in the early-90s, during my elementary years. I had to hide it from the family because they don't like the idea; and back then, it was believed it will damage your eyes. (Unless the lens is plastic.)

My fancy glasses was the Einstein model. Haha.

I now wear prescription glasses because #astigmatism. It was 2011 or 2012 when I switched to “real ones”. Many of my co-workers around that time also wore fashion eyeglasses. ^_~

Also, there are more reasons to wear zero-grade eyeglasses today, two such are computers and blue light. Some of the people I know wearing glasses are only wearing it for extra protection.

This is me 🤓

Has anyone got, seen, or can make up mock-ups of how points of light (or... very bright text on a dark background) can look to someone who suffers halos with astigmatism?

If yes to any of the above, may I use them in a talk?

Thank yooouuuu in advance!

Ugh. #Astigmatism corrections are THE WORST. Mine seem to float all over the place from day to day.

It took FOUR tries to get my latest pair right, and even then some days they’re *still* blurry.

Astigmatism. Sucks.

I was going to post this last night but forgot to. Turns out I have #astigmatism, which means either my lenses or something else with my eyes is egg-shaped and not focusing the light properly so for me far things appear blurry.

New glasses have arrived! I can see clearly again.

This is what $1400 buys you.

Do you prefer 1 or 2?

I’ll do that again.

Do you prefer 1 or 2?

I was in grad school taking an optics class before I learned that people are NOT supposed to see like this at night. #Astigmatism

Simply out of curiosity:

Which of the following applies to you:

#Glasses
#Astigmatism

For anyone else into self-measurement of #eyesight, here's a tool I just made to help you figure out what the axes of your #astigmatism are (if present): https://jeremy.org/misc/astigmatism.html
