Customers overwhelmingly appreciate the Square Glasses from Zenni, highlighting their stylish design, lightweight feel, and comfort. Many users report excellent visual acuity and value for money, expressing satisfaction with the fast delivery and ease of the ordering process. However, some reviews indicate issues with fit, specifically around the nose and temple length, which could cause the glasses to slip. Despite these minor concerns, the positive sentiment around the glasses' quality and aesthetic far outweighs the negatives.
