Eyeglasses Size and Ordering Guide
Choosing prescription eyeglasses online starts with a frame that fits and the lens options that match your prescription. This guide explains the measurements and the choices you will see on MigliorEyewear product pages.
Understand frame measurements
Frame sizes are usually shown as three numbers in millimeters, such as 52β17β145:
- Eye size (52 mm): the width of one lens.
- Bridge (17 mm): the distance between the lenses across the nose.
- Temple length (145 mm): the length of each arm.
Compare these numbers with a pair you already wear comfortably. A few millimeters can change how a frame feels, and the frame's shape and design also affect fit. Each product description lists that frame's measurements, color, material and shape.
How to order
- Choose a frame. Browse the eyeglasses collection, open a product, and check its measurements and details.
- Choose frame and single-vision usage. Product pages offer a βNoneβ choice and single-vision prescription lens choices for distance, computer or reading use. Select the choice that matches your order. If you want the frame without prescription lenses, review the βNoneβ choice and the order summary before checkout.
- Choose lens options. The product form may ask about anti-glare coating, Transitions, polarized lenses and lens material or thickness. Read each available choice and check the updated price before adding the frame to your cart.
- Enter your prescription details when ordering RX lenses. Use the fields for your right eye, left eye and pupillary distance (PD). Copy the values exactly from your current prescription and your PD measurement. If a value is missing or you are unsure which lens option to choose, contact us before placing the order rather than guessing.
- Review your cart. Confirm the frame, lens choices, prescription details and total before checkout.
