Polycarbonate
is up to 10 times stronger than plastic
lenses, has UV protection built into the
material, and is nearly half as thin as
regular plastic. It’s the material
which has long been recommended for
children’s eyewear, as well as for
sports eyewear and industrial eye
protection.
Plastic lenses
are lighter, thinner, and retain a similar
optical quality to glass. It is the
cheapest lens material, however it is not
always recommended for use in higher
prescriptions as they can be very thick
compared to other lens materials.
Trivex
is a relative newcomer in lens materials.
It is the lightest of all lens materials,
has built-in UV protection, is resistant to
stress cracking and has excellent optics.
It is a recommended material for
children’s eyewear, as well as
rimless drilled frames and sportswear.
Trivex is a mid index product and can be
surfaced to a 1mm center thickness. This
material outperforms poly in ballistic
testing, so it is a very safe choice for
children.
