At King Cross opticians, we stock a complete
range of Lenses.
When we reach middle age we all start to suffer from presbyopia.
This very often means that it becomes necessary to have two pairs
of spectacles, one for distance vision and the other for close work.
Due to life styles, work and hobbies it is not always convenient
to keep changing spectacles.
Bifocals combine both distance and reading prescriptions into one
lens. They have a dividing line to make the transition from distance
At King Cross Opticians, We only use the latest design Varifocals.
Varifocals, or progressive lenses as they are sometimes referred
to, are similar in concept to bifocals.
They combine both
distance and reading prescriptions into one lens. Unlike bifocals
they do not have a dividing line as the prescription is blended.
This blending not only enhances the focusing range of your prescription
but, without a dividing line, improves the appearance of the spectacles.
The advancement in materials and lens design has meant that we
can now produce lenses that are up to 45% thinner than standard
The benefits being that not only are the lenses lighter and therefore
more comfortable to wear the appearance is improved, especially
if combined with an anti reflection coating.
These lenses are sensitive to ultra violet light and turn to a
darker shade when subjected to UV light.
Generally available in either Grey or Brown they provide a comfortable
tint for every day wear and can also be used for sunglasses in all
but very bright conditions.
