RIVBOS Kids Sunglasses RBK004-2: Polarised UV protection with a secure strap
Product description
The essentials
If you’re buying sunglasses for younger kids, the usual worries quickly pile up: will they break, will they stay on, and—more importantly—are they really doing something for their eyes? RIVBOS Kids Sunglasses (RBK004-2) are designed around those practical problems. On paper, the combination of a soft silicone-style frame and polarised lenses aims to make everyday wear more comfortable while keeping glare under control.
They’re positioned for children aged 3–10, and the included glasses strap is a big part of the pitch. That detail matters for day-to-day use: when kids are moving, bending, or just forgetting they’re wearing sunglasses, a secure strap can stop them becoming a “where’s it gone?” mission.
Key points

What stands out is the focus on both comfort and protection. The frame is made from a soft silicone/unbreakable-style material that’s described as durable and less likely to break, which is a sensible approach for kids’ accessories that take a fair bit of rough treatment.
On the lens side, the brand claims the sunglasses can filter UVA, UVB, UV400 and harmful blue light. Polarised lenses are also included to reduce glare and help restore true colours—useful if your child will spend time outdoors around reflective surfaces like pavements, water, or bright open spaces.
One practical touch here is the strap: it’s described as uniquely designed to firmly fix the glasses on the child, so slipping is less likely. It’s also framed as usable even for very young wearers (within the stated age range), though the fit experience can still vary from child to child.
What you’ll notice day to day



This kind of kids sunglasses is all about the small wins. A softer, flexible-looking frame tends to feel more comfortable than rigid plastics, especially if your child is wearing them for longer spells at the beach or on a family day out.
Polarised lenses can make a visible difference when glare is strong. So if your kid keeps squinting in bright sun, these are aimed at making the world a bit easier to look at.
The strap should also reduce the hassle factor. Imagine a typical UK summer afternoon: a short walk to the park, a quick play session, then back in the car. Without a strap, sunglasses often end up dangling, lost, or pushed up. With one, you’re more likely to keep them where they belong.

Note: The product name mentions UV protection and polarisation, but the provided details don’t include lens size, frame dimensions, or weight—so if you need exact measurements for a precise fit, you may want to double-check the listing details.
Where it shines (and where it might not)
Where it shines is when you want a straightforward kids’ setup: soft, durable frame materials combined with polarised lenses and a strap that’s meant to keep the glasses on.



It might not be the best choice if your child is particularly hard on accessories but still prefers very lightweight, minimal-feel frames. The strap is helpful, but it also means the glasses are always associated with a fixing method, and some kids simply dislike anything that feels “attached”. Also, while UV filtering and UV400 are claimed, the information provided doesn’t list certification or testing specifics, so you’re trusting the stated protection details rather than anything you can verify from this description alone.
How to choose wisely before you buy
Before committing, check whether your child’s face size sits comfortably within the 3–10 range, because kids’ sunglasses can vary a lot in coverage and how they sit at the nose and cheeks. Next, look at how you’ll actually use them: a strap is most useful if your child is outdoors and moving around a lot.
It’s also worth thinking about your expectations for polarised lenses. They’re good for glare reduction and colour appearance, but they won’t replace proper supervision or safe sun habits.

Finally, if you’re buying for a holiday or frequent outings, durability is usually the deciding factor—this model is clearly built with that mindset.
Mini FAQ

What UV protection do they claim?

Final verdict
RIVBOS Kids Sunglasses RBK004-2 make a lot of sense if your priority is hassle-free outdoor wear: comfortable-to-wear soft frame materials, polarised lenses for glare, and a strap designed to help keep the glasses in place. It’s a practical pick for most active kids in the stated age range.
You may want to skip them if your child dislikes strapped accessories, or if you specifically need verified certification details and measurements beyond what’s included here. In short: for everyday family sunshine and park/play sessions, they tick several boxes—just be realistic about the strap being part of the experience.
