Collection: Ralph Sunglasses Under £100

If you want a genuine designer name without a three-figure price tag, our edit of Ralph sunglasses under 100 is the place to start. Every frame here is authentic Ralph by Ralph Lauren, sold as an authorised stockist, and priced between roughly £60 and £80 — so the whole collection sits comfortably beneath the £100 mark. With around 143 styles to explore, it is one of the broadest affordable designer sunglasses ranges we carry, spanning cat-eye, square, round, rectangle and butterfly shapes for a huge variety of faces and tastes.

What you get in the Ralph sunglasses under 100 collection

Ralph is Ralph Lauren's more relaxed, fashion-forward line, and it is deliberately built to be accessible. That does not mean it skimps: you still get quality acetate and metal frames, UV-protective lenses, and the understated Ralph detailing that makes these sunglasses feel considered rather than throwaway. Popular models in this price band include the RA5305U, RA5150, RA5293, RA5160 and RA5319U, which cover everything from bold oversized fashion frames to slimmer, everyday shapes.

Because the collection is so large, it is a great entry point if you are buying designer eyewear for the first time, replacing a lost pair, or simply want a second colourway for a change of look. And since these frames are affordable, many shoppers pick up two or three styles to rotate through the season. If you like the idea of an affordable designer buy but want to compare across labels, our wider designer sunglasses UK hub and the main sunglasses collection show what else sits in a similar range.

Choosing Ralph sunglasses under 100 by face shape

With so much choice, face shape is the quickest way to narrow things down. The simple rule is to contrast your frame with your face:

• Round face: add angles with a square or rectangle frame for definition.
• Square face: soften strong lines with round or oval shapes, or a cat-eye.
• Heart face: balance a wider brow with cat-eye or gently rounded styles.
• Oval face: lucky you — almost every shape works, so choose on style alone.

To shop by silhouette, we have dedicated shape pages including cat-eye sunglasses, round sunglasses and square sunglasses, all of which include Ralph styles alongside other designers.

Men's, women's and unisex options

This affordable Ralph collection is largely women's-led, with plenty of cat-eye and butterfly frames, but there are unisex pilots and squarer shapes too. If you are shopping specifically for her, our women's sunglasses page filters the range further. Ralph's sizing tends to run true, so if you know your measurements you can buy with confidence.

Understanding sizing and fit

Every pair lists three numbers inside the temple arm — lens width, bridge width and temple length (for example 54-18-140). The middle number matters most for comfort: a wider bridge suits a broader nose, a narrower one suits a slimmer face. Lens widths around 51–53mm read as neat and classic, while 56mm and above give a bolder, more oversized fashion look that is very much on trend. If you are unsure, compare against a pair you already own and like.

Lens tints and what they do

Under-£100 does not mean under-protected. Ralph lenses offer full UV protection, and across this collection you will find:

• Solid smoke or brown tints for classic, all-purpose sun cover.
• Gradient lenses that fade from darker at the top to lighter at the bottom — flattering and great for driving.
• Mirrored and coloured tints for a sportier, more fashion-led statement.

If glare on the road or water is your main concern, consider a polarised upgrade — see our polarised sunglasses range for options.

Prescription options at Ardor

Being budget-friendly does not rule out prescription wear. Most Ralph frames in this collection can be glazed with your prescription — single vision, varifocal, bifocal, blue-light, tinted or photochromic. It is a smart way to get designer prescription sunglasses without spending a fortune on the frame itself. Prescription orders are glazed to order and usually take around 7–10 working days. Browse our prescription sunglasses section to get started, and for everyday clear lenses see our glasses collection.

Why buy from Ardor

Affordable designer eyewear only makes sense if it is the real thing. As an authorised UK stockist, we guarantee every pair is genuine Ralph, supplied with the branded case and cloth. You also get free UK shipping and a straightforward 14-day returns policy (you cover return postage), so buying a sub-£100 pair online is low-risk. It is the reassurance of a designer purchase at a price that leaves room in the budget for a second style.

Building a small sunglasses wardrobe on a budget

Because Ralph sunglasses under 100 are so affordable, this collection is ideal for building a versatile little wardrobe of frames rather than relying on a single pair. A classic tortoiseshell square covers work and travel; a bold black butterfly or cat-eye handles holidays and glamorous occasions; and a colourful acetate keeps weekends fun. Rotating between two or three styles also spreads the wear, so each pair lasts longer and stays looking newer. It is a genuinely practical way to enjoy designer eyewear without a designer-sized outlay, and it means you always have the right frame to match your outfit, the occasion and the light conditions of the day.

Frequently asked questions

Are Ralph sunglasses under 100 real designer frames?

Why are these Ralph sunglasses cheaper than other designer brands?

Can I get prescription lenses fitted under £100 total?
