* Monovision--spectacle dependence is reduced overall by targeting distance vision in one eye (usually the dominant eye) and near or intermediate vision
in the other eye.
Implantation of diffractive multifocal IOLs (MIOLs) provides excellent distance and near vision in patients who undergo refractive lens exchange and cataract surgery [2-11], but the main drawbacks are visual symptoms such as halos and glare [3,4,7] and with bifocal MIOLs, poor intermediate vision
Good distance and near vision are well demonstrated in multifocal IOLs but intermediate vision
is often variable, particularly in dim light.
However, the intermediate vision
, which is important for most people in daily activities, for example, computer use, shopping, and cooking, was rarely reported .
The company is highlighting that the new active linear progressive corridor offers a smooth transition from distance vision before accelerating into intermediate vision
Although this design is ideal for pilots, plumbers, and electricians it could also be used for computer use, art, board games where intermediate vision
is required at eye level and the distance prescription can be supplied in the top segment.
Mr Jensen praised the success of a recent series of workshops organised by Rodenstock to give independents the skills to help increase their sales of near and intermediate vision
But it's the quality of the near and intermediate vision
that is so impressive.
A MAJOR national campaign to help independent opticians increase their sales of near and intermediate vision
spectacles has had a dramatic impact, according to Rodenstock UK.
