I can't close one eye at a time...

Updated on May 7, 2012

Closing One Eye at a Time - Not everyone can.

If you can't close one eye at a time, you're not alone. Neither can I.

I've always had trouble closing one eye at a time, and also with winking with one eye.

Some optometrists say that it's a genetic ability that you can't learn. Other people advise practicing.

There are many reasons to want to be able to close one eye at a time, for example, looking through a microscope, adjusting the focus on binoculars, using a scope on a rifle, etc. Sometimes this skill is necessary for work.

If you need to close one eye at a time, but can't, try an eye patch! - It might look funny, but it solves the problem.

This eye patch has a soft, foam seal for comfort and also to keep all light out. It is adjustable to fit all sizes.


Here's a helpful tip:

Try keeping both eyes open, and teach your mind to ignore the image from one eye.

This is what I'm working on. I've heard that it takes practice but that you can do it.

Can you close one eye at a time? - The ability to control one eye at a time varies from person to person

Winking is closing one eye at a time quickly. It is often done to convey a signal or message, like a joke or a sign of affection. Winking is one of the reasons a person might want to only close one eye at a time.

The ability to wink is often learned by kids, but some adults can't wink even after much practicing.

Can you wink?

Having trouble using a microscope? - Try a Binocular Microscope or an LCD Microscope

I had trouble in school because I had to always use my hand to cover one eye to look through the microscope in biology class.

One solution is to use a different kind of microscope, like a binocular microscope, LCD microscope, or a USB microscope that hooks up to the computer.


Make Using Binoculars Easier - I use my binoculars on a tripod. It makes adjusting the focus A LOT easier!

I always had trouble focusing binoculars because you have to close one eye at a time to get the focus right. I bought a tripod adapter like this one so that I could use my binoculars on my tripod so that they would keep steady. To my surprise, having my binoculars on the tripod freed up my hands, and now I use one hand to cover each eye as I adjust the focus!

I watch American Bald Eagles with my binoculars, and being able to have them properly focused has made a world of difference! Of course using an eye patch would have also worked. However, my binoculars are too shaky without the tripod. I've read that using a tripod is recommended for binoculars over 10x and I'd have to agree!


Can you close one eye at a time? - Have you ever had this problem, or something similar? Do you remember learning to wink? I'd love to hear about it!

      I can close my right but when I try to close my left I can't keep it closed and it triggers twitching that involves all the muscles surrounding both eyes and it ends up looking like I'm having a seizure. I've always had this problem. When shooting I use my right hand but left eye.
