lenses. The wait is over! The latest generation of plastic changeable
lenses just released in 2002 is finally a great product. Virtually
all the past negatives have been addressed in this fourth generation
design. These lenses are now clear indoors (no residual tint) and
turn to dark sunglasses with direct exposure to sunlight in less
than a minute.
Since it requires direct sunlight to change, its only remaining
downside is its inability to change much inside a car. These lenses
are scratch resistant and are available in a full range of materials
and lens choices.
