Consider The Distance Between The Customer’s Pupil And The Eyeglasses Frame Size
As long as the design of the discount prescription glasses frame is reasonable, it feels comfortable and stable when trying on, and the nose support fits well, then of course it can be a little lighter.
There is a prism effect in the peripheral area of the lens, which is more pronounced in large frames than in small frames. Especially for people with high myopia and astigmatism, it is more likely to cause peripheral visual distortion and discomfort after fitting glasses.
The significant difference in pupillary distance and frame size results in the inability to meet the optical area during lens processing, causing the center of the lens to not align with the visual center and affecting visual quality.
The discount prescription glasses fitting needs to consider the relationship between the distance between the customer's pupils and the size of the frame. Even for customers who are suitable for large-frame glasses, it is recommended to have a high pupil to avoid a low optical center. Those who wear glasses with large frames say that looking up makes things clearer, but this is actually because the optical center of the lens is too low.
Myopia lenses are concave lenses (thin in the middle and thick on both sides). The larger the frame, the thicker the edges and the overall weight of the glasses increases, which can easily compress the nose bridge and cause the glasses to fall. It is generally not recommended to choose a large frame when myopia exceeds 600 degrees.
Nowadays, everyone pursues fashion. Whether in daily life or in movies and TV shows, large-frame glasses can be seen everywhere. Many people believe that large frames can accentuate a smaller face, which is exactly where the trend of retro fashion lies.
