    I will put a pair of eyeglasses that are customized to my vision inside a rubber eyecup.
    And I'm going to use gaffer tape or something to secure it.

    Re: Nightvision goggles for developing film?

    I went to the optician today. The optician told me that he can make my nearsighted lenses in about 20 minutes and the cost is about 30,000 South Korean won(about $22).
    I will go again in a few days.

    Anyway, I recently purchased an additional 2509N reel.
    And now I'm going to trim the nodges on this reel.
    I'm okay with small marks, but I don't want big, dark marks like this.
