"Once a Day! Eye-Improving Spot the Difference" Ken Wakasugi Vision Improvement While Having Fun Also Relieves Eye Strain For those suffering from: Nearsightedness, Presbyopia, Smartphone-induced Presbyopia, Blurred Vision, and Narrowing Field of Vision Due to Aging Price: ¥1300 + tax Purchased 1-2 years ago, I've roughly completed it once. There are no creases, and it's in quite good condition, so I'd love for someone to use it. I think the fact that you can start from any page makes it easy to enjoy, and there's a time limit, so you move your eyes a lot, which I believe is definitely good exercise for the eye muscles. There are various pictures, and I took some photos of the autumn-themed ones (photos 3 and 4) for your reference. #KenWakasugi #Ken_Wakasugi #Book #Nature/Medical_Science/Health"
