Ray-Ban Meta Blayzer Optics size: 50-19 mm or 54-19 mm?

The Ray-Ban Meta Blayzer Optics size options are 50-19 mm and 54-19 mm. The first number is the width of one lens and the second is the bridge, both in millimetres. The bridge is 19 mm on both, so you are choosing between a 50 mm lens and a 54 mm lens.

Short answer: order the size closest to the glasses you already wear comfortably. If your current pair is marked around 50, take the 50-19 mm. If it is marked around 54, or frames tend to feel tight at the sides of your head, take the 54-19 mm. The rest of this guide shows how to check, and what else changes between the two.

What 50-19 mm and 54-19 mm mean

Eyewear sizes are written as lens width, then bridge width. On the Ray-Ban Meta (Gen 2) Blayzer Optics, 50-19 mm means each lens is 50 mm wide and the bridge between the lenses is 19 mm. The 54-19 mm keeps the same bridge and widens each lens to 54 mm.

The larger size grows in other directions too. The product page lists these measurements:

So the 54-19 mm is 4 mm wider per lens (8 mm across both lenses), 2.8 mm taller in the lens and 5 mm longer in the temples. Across a face, 8 mm is enough to change where the frame edges sit against your temples.

Which Ray-Ban Meta Blayzer Optics size to order

Start with a pair of glasses that already fits you. Look inside one temple arm. Most frames have three numbers printed there, such as 52-18-145: lens width, bridge, temple length.

• Lens width of 51 or below on your current pair: the 50-19 mm will feel familiar.
• Lens width of 53 or above: go for the 54-19 mm.
• Exactly 52: look at how that pair fits. If it sits comfortably with room to spare, lean towards the 50-19 mm. If it pinches behind the ears or leaves marks at the sides of your head, lean towards the 54-19 mm.

If your frame has no numbers, measure one lens at its widest point with a ruler, in millimetres, and compare the result with 50 and 54.

Your prescription matters too. If you wear progressive or bifocal lenses, give your optician the two lens heights (36.3 mm and 39.1 mm) before you order. They can tell you which size suits your lenses, and confirm they can fit lenses to this frame.

The bridge is not part of the decision, since both sizes use 19 mm. The product page describes all frames as Universal Fit, with flexible nose pads to adjust how the frame sits on your nose.

The 14 colour and size combinations

There are seven frame colours, and each one is listed in both sizes, which gives 14 combinations:

• Shiny Transparent Black
• Matte Black
• Shiny Havana
• Matte Transparent Ice Grey
• Shiny Transparent Dark Olive
• Polished Transparent Ocean Blue
• Shiny Brick Brown

On the product page, colour and size are chosen together, for example “Matte Black / 54-19 mm”. Before you pay, check that the size in your selection matches the one you decided on. All frames use injected material, and the style number is RW7001 if your optician asks for it.

The demo lens and the adjustable parts

Every combination ships with a demo lens. That is a plain placeholder with no prescription, there until your optician replaces it. Prescription, blue-light and Transitions lenses are not included, so plan to have your own lenses fitted after the frame arrives.

Three parts of the frame help you tune the fit:

• Flexible nose pads
• Adjustable temple tips
• Hinges with an extra 10 degrees of rotation

These handle the fine fit. They do not turn a 50 mm lens into a 54 mm one, so get the size right first.

The technology is listed once for the frame, with no difference noted between sizes: 3024 x 4032 photo capture and up to 3K video, two open-ear speakers, six microphones, touch and voice controls, 32 GB storage, Wi-Fi 6 and Bluetooth 5.3. Battery life is listed as over eight hours, with the charging case providing up to 48 additional hours, depending on use.

The Blayzer Optics needs the Meta AI app on a compatible phone, a Meta account and internet access. The page lists iOS 18.6 or Android 15 as the minimum software, and the glasses are for ages 13+. AI and voice features depend on country and language, so features such as translation work only where available.

If neither size feels right

The Ray-Ban Meta Scriber Optics (Gen 2) is the other frame described as designed for prescription wearers. It starts from RM2,229, comes in six colours with clear demo lenses, and has adjustable temple tips and interchangeable nose pads. Its listing shows colour options only, so check the product page for measurements.

The Ray-Ban Meta Headliner (Gen 2), from RM1,729, handles fit differently. You choose High bridge fit or Low bridge fit, then one of seven frame and lens colours, including clear, polarized and Transitions lenses. Low bridge fit is listed on some colours only.

For reference, the Meta Store USA listed the Scriber Optics at USD 499 and the Headliner at USD 379 to USD 459 on 10 November 2026. When you compare a US list price with an RM price, account for currency conversion, delivery to you and how returns would work.

Price and how ordering works

The Blayzer Optics is priced from RM2,219, which covers the frame with demo lenses. Budget separately for prescription lenses from your optician.

It is a preorder. We buy the frame new from the US brand store after you order, and estimated delivery is 30 calendar days. You can pay in full, or use the optional 50% deposit shown on the product page and pay the balance later (checkout shows when the balance is due for your country).

Delivery is free within Peninsular Malaysia. Sabah, Sarawak and Labuan pay RM21 per item, or nothing on orders over RM 2,200. Every other country sees its fee at checkout, and the shipping fees page has the details.

Returns are accepted within 30 days of delivery. A change-of-mind return must be in new condition, carries a 10% restocking fee, and the cost of shipping it back to the seller is deducted from your refund. Exchanges are only for items that arrive damaged, so swapping a 50-19 mm for a 54-19 mm means a return and a new order. Settle the size before an optician fits lenses, and report any damage with photos as soon as the glasses arrive. Full terms are on the refund and returns page.
