Biotrue OneDay for Presbyopia are multifocal
contact lenses produced by Bausch and Lomb.
Presbyopia is a common vision defect that occurs as a natural consequence of the
aging process, and often begins to affect people around the age of 40. The onset
of presbyopia is defined by a deteriorating ability to focus on nearby objects.
Three optical zones
Biotrue ONE day
for Presbyopia contact lenses provide an effective solution for vision
correction at all distances. Their special, three-zone design uses the natural
properties of the eye when focusing on distant, near, and middle-distance
objects. The individual optical zones are situated in concentric circles, with
the innermost circle providing a clear view of nearby objects, and the outermost
ring providing a view of distant objects.
High water content and
comfortable fit
To create Biotrue OneDay for
Presbyopia contact lenses, Bausch & Lomb uses HyperGel material (Nesofilcon
A) that combines the features of classic hydrogel and silicone hydrogel to
achieve a high water content and a high oxygen permeability. HyperGel technology incorporates the
active ingredients in the upper layer of the lens material, creating a lipid
layer that prevents dehydration. BioTrue ONEday have a water content of 78%,
which is among the highest on the market.
Protection against UV
radiation
Biotrue OneDay for Presbyopia
contact lenses are equipped with a UV filter that absorbs some of the sun's harmful UVA and UVB
rays. However, it should be noted that contact lenses with UV filters should not
be considered as a full replacement for sunglasses because they do not cover the
entire surface of the eye. It is always best to combine contact lenses with
UV-blocking sunglasses.
