Looking for affordable prescription eyeglasses online? Carfia’s Premium Prescription Eyeglasses collection offers 20% off eligible items when the qualifying purchase reaches US$49. The discount applies automatically at checkout. Compare the six frames below by shape, material, and measurements, then confirm lens arrangements before ordering.
How to get 20% off prescription eyeglasses
Start with the prescription eyeglasses collection and choose your preferred frames. The automatic OCT20 promotion gives 20% off eligible collection items with a US$49 minimum purchase. You do not need to enter OCT20 as a coupon code.
The minimum matters: each of the six individual frames featured here is currently priced below US$49, so one of these frames alone does not reach the promotion’s threshold. Review your qualifying subtotal and the discount shown at checkout before completing payment. Do not assume the offer combines with other promotions.
Five things to know: the offer is automatic; the minimum purchase is US$49; the discount applies to eligible collection items; frame measurements vary by model; and prescription-ready does not mean prescription lenses are included. Prices and promotion availability can change.
Six prescription-ready frames to compare
These are the first six products in the collection’s default order when this guide was prepared, not a sales ranking. Whether you are searching for lightweight oval prescription glasses frames, large square acetate eyeglasses, or round tortoiseshell prescription glasses frames, this selection gives you distinct starting points.
1. Aeoria-FC03: large square acetate eyeglasses
Aeoria-FC03 pairs a deep brown upper rim with a translucent lower frame and gold-tone corner accents. Its softly rounded square silhouette gives the design structure without sharp corners. The listed frame width is 147 mm, with 53 mm lenses, a 19 mm bridge, and 148 mm temples. Current listed price: US$33.00 before any qualifying discount.
If your search is for large square eyeglasses frames, compare these measurements with a pair you already wear comfortably rather than choosing by appearance alone.
2. Bonterey-FC03: rimless oval metal eyeglasses
Bonterey-FC03 offers a visually minimal alternative to full-rim acetate. Its oval lens outline is paired with a gold-tone metal bridge and tortoiseshell temples. Listed at 18 g, it measures 136 mm across the frame, with 53 mm lenses, a 20 mm bridge, and 140 mm temples. Current listed price: US$32.00.
For shoppers comparing rimless oval prescription frames, this model is worth reviewing for its understated design. The listing describes single-vision, bifocal, and progressive compatibility; confirm suitability for your individual prescription with your lens provider.
3. Ovalen-FC2: oval acetate prescription frames for women
Ovalen-FC2 combines a slim oval shape with a full-rim acetate construction. The tortoiseshell finish brings warm, dark tones to a compact-looking silhouette. Listed specifications include an 18 g weight, 139 mm frame width, 52 mm lens width, 18 mm bridge, and 142 mm temples. Current listed price: US$34.00.
Explore the oval acetate prescription frames if you prefer a defined rim rather than a rimless design. The product listing describes compatibility with single-vision, bifocal, and progressive lenses; final lens suitability should be confirmed separately.
4. AvonPaK-FC17: round frames with colorful patterned acetate
AvonPaK-FC17 adds a colorful option to this selection. The displayed product image shows blue and amber accents across the patterned round front, paired with a gold-tone double bridge. The listing gives a 139 mm frame width, 47 mm lens width, 24 mm bridge, 146 mm temples, and 28 g weight. Current listed price: US$33.50. This is a frame-only product; prescription lenses are not included.
5. AvonPaK-FC03: round tortoiseshell prescription glasses frames
Prefer a traditional tortoiseshell palette? AvonPaK-FC03 combines warm amber and brown patterning with round full-rim lenses and a gold-tone double bridge. It shares the listed 139 mm frame width, 47 mm lenses, 24 mm bridge, 146 mm temples, and 28 g weight of the other featured AvonPaK models. Current listed price: US$33.50. Prescription lenses are not included.
6. AvonPaK-FC28: transparent brown round eyeglasses
AvonPaK-FC28 keeps the round double-bridge shape in a transparent brown finish. Choose it for a more uniform color treatment than the patterned FC17 or FC03. Listed measurements are 139 mm frame width, 47 mm lens width, 24 mm bridge, and 146 mm temples, with a 28 g weight. Current listed price: US$33.50. The listing specifies frame only, with lenses not included.

How do you choose prescription eyeglasses online?
Start with fit, then compare shape and color. Check the frame width, bridge width, lens width, and temple length against your existing glasses. A 147 mm square frame and a 136 mm rimless oval frame can look very different on the same wearer, even when their lens widths match.
For shoppers seeking lightweight prescription glasses frames for everyday wear, Bonterey-FC03 and Ovalen-FC2 both list an 18 g weight. Those who prefer a round acetate frame with a metal double bridge can compare the three AvonPaK finishes. Weight and measurements are useful comparison points, not a guarantee of personal comfort.
Before purchase, confirm whether you are buying a frame only, how prescription lenses will be supplied, and whether the selected frame suits your prescription. Do not assume clear product-photo lenses include your prescription or a particular coating. For complementary items, browse the glasses accessories collection separately; do not assume accessories qualify for this collection-specific offer.
Frequently asked questions
Do I need a coupon code for the 20% offer?
No. OCT20 is an automatic promotion for eligible items in Carfia’s Premium Prescription Eyeglasses collection, with a US$49 minimum purchase. You do not need to type OCT20 into a discount-code field. Check that the qualifying subtotal is reached and the discount appears at checkout before you pay.
Can I buy just one featured frame and get 20% off?
One of these six frames alone does not meet the US$49 minimum at the prices listed in this guide. They currently range from US$32.00 to US$34.00 each. Your purchase must satisfy the offer’s minimum requirement, and the reduction applies to eligible collection items. Verify the final calculation at checkout.
Are prescription lenses included with these eyeglasses?
Do not assume so. The featured AvonPaK listings explicitly describe frame-only products with prescription lenses not included. Prescription-ready means a frame is intended to accommodate prescription lenses, not that customized lenses come with the displayed price. Review the individual listing and confirm lens arrangements and compatibility before you order.
Which frame should I choose for an understated look?
Bonterey-FC03 is the most visually minimal option in this selection, with a rimless oval design and gold-tone bridge. Ovalen-FC2 offers an oval alternative with a defined acetate rim. Compare their measurements, not just their silhouettes: Bonterey lists a 136 mm frame width, while Ovalen lists 139 mm. Personal fit remains the deciding factor.
Choose the frame shape and measurements that suit your needs, build a qualifying purchase of US$49 or more, and confirm your automatic 20% saving before completing checkout.
