Prescription Sunglasses Wholesale: Options for Optical Retailers
Prescription sunglasses are one of the most under-served products in eyewear retail. Customers who wear glasses often want one pair that corrects their vision and protects their eyes from the sun, and many walk out with two pairs instead — one prescription frame and one cheap pair of over-glasses. Here is how prescription sunglasses work at wholesale, and how an optical retailer can offer them without tying up cash in stock that only fits one customer.

Three Routes to Prescription Sunglasses
There is no single way to offer prescription sunglasses, and the right route depends on whether you have a lab, how specialised your customers are, and how much you want to invest.
Rx-able plano frames. You stock sunglasses frames that are designed to take a prescription lens, and a lab glazes them to the customer's Rx. This is the standard optical model: it gives the customer a genuine fashion frame with their prescription in it, and it works for any independent optician who already has a lab relationship. Your stock is the frames, not the prescriptions.
Custom prescription orders. The customer's prescription is sent to the factory or lab and the pair is made to order. This suits a strong or unusual prescription, or a customer who wants a specific frame and lens combination. It is slower than glazing a stocked frame but gives the widest range of options.
Clip-on and fit-over designs. The sunglass layer clips onto or fits over the customer's existing prescription glasses. No lab, no Rx fulfilment, and no unique-to-one-customer stock — it is a simple accessory that solves the problem for the enormous number of people who already wear prescription glasses and do not want a second pair. For a retailer entering the category, this is the lowest-risk first step.
Choosing Rx-Able Frames
The single most common mistake in prescription sunglasses is choosing the frame for its looks and discovering later that it will not take an Rx well. A prescription lens is thicker and heavier than a plano lens, and the frame has to carry that without distortion or failure.
The frames that handle a prescription best share three traits: a full rim that holds the lens securely all the way around, a reasonably rigid front that does not flex under the extra lens weight, and a shape and size close to the customer's face, so a strong prescription does not sit at an odd angle. Very thin acetate fronts, oversized fashion shapes and rimless designs can all struggle — they may distort the vision or fail to hold the lens properly.
This is why "Rx-able" is a genuine specification. A frame either takes a prescription well or it does not, and the difference is not visible in a product photo. When sourcing, ask the supplier to confirm Rx-ability per model, and test with a strong prescription before committing to a large order of a new shape.
Lens Materials & Coatings That Matter
Once the frame is confirmed, the lens is where the product is defined — and where the customer's satisfaction is won or lost.
CR-39 resin is the optical standard: excellent clarity and scratch resistance, ideal for everyday Rx sunglasses at a moderate prescription. Polycarbonate is the impact-resistant default for sport, active wear and children — thinner and lighter for a given power. High-index materials keep strong prescriptions thin and light, essential when standard CR-39 would look thick and heavy in the frame.
Then the coatings, in order of priority: UV400 first (a safety requirement, not an upgrade), then anti-reflective (AR), which matters more on Rx lenses than on plano because the thicker lens reflects more light back at the eye, then scratch-resistant for durability, and hydrophobic/oleophobic for water and oil repellence. A basic Rx lens and a fully coated one are a different product to the customer — and the coated one is what justifies a premium price.
What to Stock (and What Not To)
The economics of prescription sunglasses come down to one rule: never hold stock that fits only one customer.
A finished Rx pair is unique to a single person's prescription, so any finished Rx sunglasses on your shelf are dead weight the moment that customer leaves. The efficient model is to stock a curated set of Rx-able frames — colours and shapes that suit your clientele — plus a lab partnership, and make each prescription pair to order. You carry the frames, not the prescriptions.
The exception is clip-on and fit-over designs, which are not prescription-specific. They can be stocked like any accessory, in a few sizes and styles, and sold to any customer who wears glasses. That is precisely why they are the easiest, lowest-risk way to enter the category, and why many optical retailers start there before adding Rx-able frames.
Working With a Wholesale Supplier
When you source Rx-able sunglasses wholesalely, you are buying capability as much as product, so vet the supplier on four points.
Rx-ability per model. Can they confirm, model by model, which frames take a prescription well — and up to what lens power? A supplier that cannot answer this is not set up for the optical market.
Lens specification clarity. Can they supply the lens materials and coatings you need (CR-39, polycarbonate, high-index, AR, UV400) and provide the test reports to prove them? Coatings and materials are where a cheap supply becomes an expensive problem.
Low MOQ on frames. Since you are stocking frames rather than finished prescriptions, you want to test several shapes at low minimums before committing. Modern low-MOQ OEM makes 100–300 units per frame realistic.
Consistency and reorders. Can they reorder a single frame reliably, and keep the same lens options available? Reorder capability is what lets you grow a proven shape instead of constantly gambling on new ones.
Get those four right and prescription sunglasses stop being a liability and start being one of your most defensible categories — because the customer who trusts you with their prescription is the customer who keeps coming back.
Frequently Asked Questions
What are the ways to make prescription sunglasses?
Three routes. First, Rx-able plano frames: you stock the sunglasses frame, and a lab glazes it to the customer's prescription — best for optical retailers with a lab relationship. Second, custom prescription orders: the customer's Rx is sent and the pair is made to order, usually for a single strong prescription or a specific frame. Third, clip-on or fit-over designs: a sunglass layer that clips onto or fits over existing prescription glasses, requiring no Rx fulfilment at all and the cheapest way to offer the benefit. Each suits a different business; many retailers start with clip-ons and add Rx-able frames once demand is proven.
Can any sunglasses frame take a prescription lens?
Not safely, no. A prescription lens is thicker and heavier than a plano lens, and that weight and thickness interact with the frame. Thin acetate fronts, very large fashion shapes and rimless designs can distort a strong prescription or fail to hold the lens securely. The frames that work best have a full rim, a reasonably rigid front and a shape close to the customer's face. This is why “Rx-able” is a real specification, not a marketing label — a frame either takes an Rx well or it does not, and a supplier should confirm it for each model.
Which lens materials should I offer for prescription sunglasses?
Three cover most needs. CR-39 resin is the optical standard: excellent clarity and scratch resistance, ideal for everyday Rx sunglasses at a moderate prescription. Polycarbonate is the impact-resistant default for active use, sports and children — thinner and lighter for a given power, though with slightly lower optical clarity. High-index materials let strong prescriptions stay thin and light, which matters for a high-minus prescription where standard CR-39 would look thick and heavy. Match the material to the customer's prescription and use, not to a single default.
What coatings are essential on prescription sunglass lenses?
UV400 first — non-negotiable, it is a safety spec, and a dark tint without it is worse than no sunglasses. Then anti-reflective (AR), which matters more on Rx lenses than on plano because the lens is thicker and reflects more; AR reduces glare from the lens surface itself. Scratch-resistant coating protects the investment and is standard on quality lenses. A hydrophobic or oleophobic layer repels water and oil, useful for sport and daily wear. These coatings are where the perceived quality and the margin live — a basic Rx lens and a fully coated one are a different product to the customer.
Should an optical retailer hold finished prescription sunglasses in stock?
Generally no. Every prescription is unique to a customer, so finished Rx sunglasses are dead stock the moment that customer walks away. The efficient model is to stock a curated set of Rx-able frames plus a lab partnership, and make each Rx pair to order. You carry the frames, not the prescriptions. The exception is clip-on and fit-over designs, which are not prescription-specific and can be stocked as a normal accessory — which is exactly why they are the easiest, lowest-risk way to enter the category.
