Brightness glitch

Hello! Fellow friends!
I've got a problem with my Minecraft. Whenever it is day time for me the sky keeps flashing dark then light
Example: http://gyazo.com/25b76393f47263f10112b3de757ec12f
It really annoys my eyes and I hope some of you know how to fix it.

 

That might just be your computer/laptop

 

Did you try closing minecraft and re-opening it?

Did you also ask if anyone online else is having this problem? As it could be the server.

 

I've had this problem for ages. And I have it on other servers. I asked my friend and apparently the issue is OptiFine with 1.8. But I still don't know how to fix it

 

Get rid of your OptiFine is the easiest solution I see.

 

It has happend to me too.

 

Try to "Direct Connect" instead of joining the server.
