Biotrue ONEday for Presbyopia
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.
