From Ghostless Everyday Wear to Ski-Slope Glare: Our 2 Photochromic Lenses Explained

The short answer: Cat 0-3 (67 Shades of Grey) is the lens for everyday life, indoor pickleball to outdoor errands to evening rides, staying nearly clear indoors and only darkening to a moderate tint outdoors, with a "ghostless" build designed to cut halos and double images around lights. Cat 2-4 (Blinded by My Own Greatness) is for when light gets genuinely extreme: snow, high altitude, blazing open water. If you're one of the many Singaporean families using these June school holidays for a ski trip to Queenstown or Wanaka, that is the category built for that glare, not the everyday one. Both are currently available to pre-order, shipping by the second week of August.

Why talk about photochromic categories right now?

Singapore's Term 2 school holidays run from 30 May to 28 June 2026, right now, and ski season across Australia and New Zealand runs from early June through late September, with winter school holidays there falling in late June and into July. A lot of families travel for exactly that overlap. That is the real-world version of extreme brightness, snow, altitude, hours outdoors, and it is a far more useful way to think about Cat 2-4 than built for mountaineers.

What do Cat 0-3 and Cat 2-4 actually mean?

The numbers refer to VLT, Visible Light Transmission, how much light actually reaches your eyes. Lenses are categorised from Category 0, around 80 to 100% VLT with no or very light tint, down to Category 4, under 8% VLT and extremely dark. 67 Shades of Grey moves across the lighter half of that scale, roughly 80% down to 12% VLT, Category 0 to Category 3. Blinded by My Own Greatness starts where that one ends, roughly 18% down to 3% VLT, Category 2 to Category 4, and never gets close to clear.

Category	VLT range	Feels like
0	80 to 100%	Almost clear, like no tint at all
1 to 2	18 to 80%	Light to standard everyday sunglasses
3	8 to 18%	Dark, strong sun protection
4	Under 8%	Extremely dark, snow or high-altitude only

Ghostless, explained

Ghostless is specific to 67 Shades of Grey. Because that lens spends time in the near-clear, low-VLT-difference zone, indoors, evenings, dusk, it is built to cut down the halos and double reflections around lights that cheaper photochromic lenses are prone to. Blinded by My Own Greatness does not need that feature since it is rarely in that low-light zone, it is built for sustained brightness instead, paired with polarization to cut reflected glare off water, snow, wet roads, sand and windscreens.

Which one matches your week?

If your week looks like...	Reach for
Indoor sport, daily commute, evening rides	Cat 0-3, 67 Shades of Grey
A ski trip, glacier trek, full day on open water	Cat 2-4, Blinded by My Own Greatness
Driving	Neither at full Cat 4 darkness, Category 4 lenses are too dark and not legal for road use in most places

Frequently asked questions

What does VLT mean?

Visible Light Transmission, the percentage of light that actually reaches your eyes through the lens. A higher number means a lighter, more see-through lens.

Why is only Cat 0-3 called ghostless?

It spends more time in the near-clear, low-light zone, indoors and evenings, where halos and double images around lights are more noticeable. Cat 2-4 rarely sits in that zone, so the feature is not relevant to it.

Can I drive in Cat 2-4 sunglasses?

Not when the lens is at its darkest. Category 4 lenses are too dark and are not legal for road use in most places.

When do these ship?

Both are pre-order right now, expected to ship by the second week of August.

Is Cat 2-4 overkill if I am not going skiing?

Not necessarily. It also suits full-day beach trips, open water and high-altitude hiking, anywhere light stays intense for hours.

Can Cat 0-3 handle full midday sun?

Yes, up to Category 3, which covers most ordinary days. It is snow and high altitude where Cat 2-4 pulls ahead.
