Great product but tough to change lenses - Walkers All-Sport Glasses w 4 Interchangeable Lenses

These are great shooting glasses, with great options. Lenses are clear with n distortion. I love the extras of getting multiple lenses and a carrying case. Glasses are easy to adjust to my head. The only difficult thing is changing lenses. The sides pop out daily easy, but the center won’t come lose easily. I’m afraid I’m going to break them each time I change lenses.
