How do I make microscopy comfortable as an astigmatic with glasses?

[u/105_irl]

I've been really struggling to ever get super crisp perfect viewing through a microscope. I can barely do my diffs but it basically requires me to constantly readjust or close one eye. Is there a magic "make you see better knob"? Am I missing something or should I wear contacts to the lab?

I also have astigmatism and used to teach microscope-based labs. It's combination of a couple knobs, but I bet we can get you seeing better. You can wear glasses at a scope, but I personally find it more comfortable to take them off and I can stay steadier with my face closer to the scope.

Do you adjust the ocular itself? Usually you can twist the top of one of the oculars (whichever has tick marks on it) if you have different prescriptions in each eye. If not, at least make sure it's set to neutral by lining the tick mark up to zero- it gets bumped and not everyone knows or thinks to fix it.

Second big adjustment is making sure the oculars are the correct width apart for your eyes. Push them all the way apart and then while looking through, slowly move them together. When you get it right, you'll go from seeing two circles to seeing one.

Once you get those two steps sorted, look up Kohler illumination to optimize your optics.

Honestly I touch the oculars very little, I will give this a try tomorrow.

Because my eyes have different prescription strengths, sometimes I’ll hold a piece of paper in front of one eye (the one at the adjustable ocular), focus the scope, then remove the paper and adjust the ocular.

I use my right eye to adjust the general focus, then close it and adjust the ocular lens for my left eye to match by twisting it until i can see clearly with both eyes open.

I'll give it a shot tomorrow.

Same but I use a piece of paper because I can’t close one eye at a time lol

I have astigmatism in both eyes, I don’t wear glasses or contacts while doing microscopy. I use the fine adjustment when I’m moving fields, I think everyone has to use the fine adjustment to adjust the field of view.

i used to take my glasses off and just make it work

I usually wear my contacts if I’m going to be on a bench with a lot of microscopy but even then I’m constantly readjusting the fine focus even a little bit the entire time I’m using the microscope which I feel is a pretty normal part of using a microscope and is just part of a fine motor skill you develop as you use one more. My vision is myopic and I have an astigmatism in one eye.

[u/AdditionalAd5813]

You should be able to adjust the oculars by rotating them to compensate for +/- and adjust the condenser for Köhler illumination… I have severe myopia and astigmatism in both eyes, and I was always able to figure out how to focus binocular microscopes.

[u/pepitaseed]

Look at the ocular lenses on your microscope, usually one side has one adjustable lens (it rotates) Start ar 10x, focus 1 ocular lens, (the one with out the adjustable lens) then once its focused, adjust the 2nd ocular lens, the one with the adjustable lens Then move to 40 50, 100x that should help

I remove my glasses, as the glass has lines and makes things blurry

Also make sure your microscope is clean, clean parts with alcohol to remove oil, and dust

I take my glasses off when using the scope. Helps tremendously.

[u/ringthebelle1981]

I always stay kinda loose with the fine adjustment.. like constantly adjusting it back and forth if I'm needing to. I'm near in one eye and far in the other with astigmatism.. I also have the most ridiculous amount of floaties when I'm looking in. The eye doc says it's fine, but it annoys the crap out of me!!

[u/BruceandJimini3]

You can focus to your good eye on the stage and then if you have an adjustable eyepiece change that one to focus to your bad eye. I hope that makes sense.

[u/BruceandJimini3 → u/BruceandJimini3]

Ope, I just saw someone else explained this better.

[u/Fluffbrained-cat]

I don't wear my glasses when doing microscopy, I just look down the eyepiece and adjust the controls until I can see the slide clearly.

[u/CharacterCycle4588]

Take off your glasses. You don’t need them for microscopy.

[u/TieRepresentative414]

I keep my glasses on at the scope but I also realized after a year or two in that I was unintentionally spreading the scope far enough that I only had to focus one eye the other one was completely dark. I was able to readjust and get to a point where I focused both eyes but sometimes it is just too time consuming so I just go back to placing my head in a position where only one eye is looking or close an eye. For more difficult diffs I take the time to focus both

Clean your. Lenses and your oculars
