Tomato Glasses vs Miraflex vs Erin’s World: Which Is Right?

Quick answer: We stock all three, and the honest answer to “which is best” is that it depends on the child’s face, not the brand’s marketing. Tomato, Miraflex and Erin’s World solve overlapping but not identical problems, and we’ve fitted enough of each to have a genuine view rather than a favourite.

One practical note before the detail: all three ranges are held at Peter Ivins Eye Care in Bearsden, and we are not aware of anywhere else in Scotland where a parent can compare them on their own child’s face in a single appointment. That is a checkable claim rather than a boast — ask.

Tomato Glasses

Adjustable bridge and temple length, built into a single frame rather than offered as a choice between fixed shapes. Where a child’s face is likely to change quickly — which is most children, most of the time — that adjustability is the whole argument. We hold the full range, over 120 frames, every model and size, which is more a statement about how much we rely on it than anything else.

Miraflex

Miraflex’s case is flexibility of a different kind — a one-piece, largely screw-free construction that bends rather than breaks under everyday abuse. Good for younger, more active children where durability under rough handling matters more than fine bridge adjustment.

Erin’s World

Built specifically around a lower, flatter bridge profile and shortened temples from the outset, rather than achieving that fit through adjustment. Developed by Maria Dellapina for her own daughter Erin, and it shows — the design decisions read as solved-for-a-real-face rather than designed-then-adapted. Where a child’s bridge is significantly and consistently flat, this is often our first reach rather than an adjustable frame.

One detail that is easy to miss: Tomato Glasses UK publishes frame weights for every model in the range. Miraflex and Erin’s World do not appear to publish gram weights publicly. That matters more than it sounds. A parent choosing a frame for a child with a high prescription — where the lens will be the heaviest component and every gram counts — cannot compare frame weight across brands without this figure. We weigh frames at the practice for exactly this reason.

How we actually decide

Not from a chart, and not before the child is in the room. We measure, we try, we watch how the frame sits and how the child reacts, and we adjust from there. If you’ve been told elsewhere that one range fits every child, that’s a sales pitch rather than a clinical opinion — no single frame does.

Questions we are asked about this

Are Tomato Glasses worth it?

For a child whose face is still changing, or one a standard frame does not suit, the adjustability is worth paying for — it is the reason we made them our first-choice range in 2013. For a child who fits a conventional frame comfortably and looks after it, a good conventional frame is a perfectly reasonable answer.

Are Tomato Glasses flexible?

Yes — the material bends and returns to shape rather than snapping, which is what makes them survive being sat on. They are not unbreakable, and no frame is. The more useful property is that the parts are replaceable, so the frame is repaired rather than replaced when something does give way.

What material are Tomato Glasses made from?

A non-toxic, FDA-approved polymer, manufactured under ISO 9001 and ISO 13485 — the latter being the international standard for medical devices, which is an unusual standard for a spectacle frame. It matters more than it sounds for a frame that will spend part of its life in a toddler’s mouth.

Which of the three is best for a very active child?

Often Miraflex, because the one-piece, largely screw-free construction takes rough handling well. But an active child with a low nasal bridge is still better served by an adjustable or purpose-built low-bridge frame, because a frame that will not stay on is not durable in any sense that helps. Activity is one factor, not the deciding one.
