RIVBOS Kids Sunglasses Polarized Rubber UV Protection RBK004-2
Product description
What it is
RIVBOS RBK004-2 are kids’ sunglasses designed to offer UV protection with a soft silicone frame and a durable, unbreakable build. They come with a unique strap to keep the glasses securely in place, aimed at children aged 3–10 and suitable for both boys and girls.
Who it’s for
If you’re looking for affordable, practical sun protection for active children who might scoot, jump and run around, these sunglasses present a straightforward option. The strap reduces the risk of loss or misplacement, which is handy for toddlers and adventurous older kids alike.

Build and comfort
The frame is described as soft silicone, intended to be comfortable against growing faces and more resistant to accidental drops than a rigid plastic alone. The unbreakable claim aligns with families prioritising durability in everyday use, from school run to outdoor play.
Eye protection and lenses


On the lens side, the glasses are positioned to filter UVA, UVB and UV400, plus provide protection from harmful blue light. The inclusion of polarized lenses is pitched to reduce glare and help restore true colours, which can support outdoor activities like biking, playground visits and family trips.

Strap and fit
A standout feature is the built-in strap, designed to secure the frames to the wearer’s head. This can be a relief for younger children or those who are quick to remove sunglasses, helping to reduce loss and the need for frequent replacements.
What to consider before buying
- The description highlights durability and a soft frame, but it’s worth checking fit for a child’s specific face shape and the strap length, as comfort comes first in daily wear.
- Polarised lenses offer benefits in glare reduction, yet for very young children or specific activities, consider whether you also want clear visibility in low light conditions.
- Availability of multiple colours/styles can influence choice, if you prioritise style, you’ll want to see the exact designs in the store.

Practical use and everyday scenarios
In the park, during family walks or on the school run, the strap helps keep the shades on when a child sits in a pushchair, runs around or climbs. If a child is particularly active, the soft frame may minimise pressure points while the UV protection helps support long periods outdoors.


Pros and cons at a glance
- Pros: soft silicone frame, unbreakable style, UV400 protection, polarized lenses, built-in strap for security, age-appropriate sizing.
- Cons: exact fit and comfort can vary by face shape, polarised lenses may affect visibility differently in certain lighting or screens, colour/design availability not detailed.

What it’s not ideal for
If you need a pair for very small toddlers below age 3, or for precision fashion matching above practical protection, this model’s suitability may be less clear without trying the fit.
Before you buy
Check the size guidance for age 3–10 and confirm strap adjustability if you expect a snug, secure fit. Consider whether you want polarisation as a primary feature or mainly UV protection with general glare reduction.

Compare and contrast


Compared with basic UV-shaded sunglasses, this model adds a strap and a more durable frame, which can be worth choosing if you value security and daily wear reliability over ultra-lightweight design. For cheaper, non-polarised options, these provide a more complete protection package at a step up in robustness and convenience.
Is it worth it?
Final verdict

If you prioritise a practical, durable option with secure fit for active kids, the RIVBOS RBK004-2 stands out as a sensible choice. It may not be the best fit if you require ultra-light fashion or non-polarised lenses for very particular activities, but for everyday protection and peace of mind, it offers clear value for money.
FAQ
- Do these sunglasses fit a 5-year-old? Yes, they’re designed for ages 3–10, but fit can vary by head size.

Final quick take
A practical pick for families seeking durable, UV-protective sunglasses with a secure strap for children who are active outdoors. It’s worth considering if you want something that stays on more reliably and offers real eye protection alongside glare reduction.
