It has no impact on vision correction

It influences the alignment of the lenses with the wearer's eyes

The shape of the frame plays a crucial role in vision correction because it affects how the lenses align with the wearer's eyes. Proper alignment is essential for optimal visual performance since the lenses need to be positioned correctly in front of the eyes to ensure that the optical center of the lenses corresponds with the pupil. This alignment is particularly important for prescriptions that include cylindrical powers for astigmatism or any complex corrections. If the shape and fit of the frame cause the lenses to sit incorrectly, it may lead to visual distortions or discomfort, ultimately compromising the effectiveness of the vision correction. Factors such as how the frame sits on the nose and temples can also influence this alignment, making it vital for both comfort and clarity of vision.
