Clear Cases That Stay Clear, Privacy That Actually Blocks

A clear case only works if it stays clear, and a privacy case only works if the numbers are real. Both come down to material and measurement rather than marketing.

Why clear cases yellow, and what actually helps

Yellowing is a chemistry problem, not a quality-control failure. UV exposure oxidises the polymer and the material ambers. Two materials behave very differently:

MaterialTypical yellowingNotes
Untreated clear TPU3–6 monthsCheap, flexible, and the reason most clear cases get thrown away
Treated PC back12–18 monthsRigid, anti-yellowing treatment resists UV oxidation
TPU edges under heavy sunSooner than the backEdges are thin and take the most UV exposure

Practical guidance: do not spec an all-TPU clear case and promise customers it stays clear. Use treated PC for the transparent panel, or accept that the bumper will amber and design around it.

Prints on clear

White or metallic print reads well on a transparent back and keeps the phone colour visible. A printed ring can also hide the magnet ring on clear magnetic cases, if a visible circle is a problem for the buyer.

What a real privacy layer measures

SpecValueWhat it means in use
Privacy cutoff≈28° off-axisReadable head-on, fades to black at the sides
Head-on transmission≈68%Slightly dimmer than bare glass; barely visible indoors
LayerTempered glass, 0.33 mmResists scratches, no edge bubbling like a film
TouchDigitizer reads normallyNo sensitivity loss on the cover display

A privacy film and a privacy tempered layer are different products. Film is cheap, scratches, and lifts at the edges within months. Ask which one you are being quoted.

Frequently asked

How long before a clear case turns yellow?

Treated PC backs typically show no visible yellowing within 12–18 months of normal use. Untreated clear TPU can amber in 3–6 months.

Does the privacy layer dim the screen?

Head-on transmission is about 68%, so it looks slightly dimmer than bare glass. Outdoors you may raise brightness one step.

Is the privacy layer glass or film?

Real tempered glass, 0.33 mm. It resists scratches and does not bubble at the edges the way film does.

Can you print on a clear back?

Yes — white, silver or full-colour UV print, or laser etching for a frosted mark.
