Open 30 presbyo - trial lens
Multifocal monthly disposable lens with natural hyaluron and TSP® ( tamarind seed polysaccaride ).
The two natural tear substitutes are continuously delivered to the eyes throughout the day, moisturizing and protecting them.
Afocal design. There is no need to consider pulley size and anterior chamber depth and the associated calculation of distance and near zones. The brain does not have to get used to the optics. The specification of an addition is omitted. The lens power is calculated from the best spherical lens for distance and an age-dependent correction value based on half the required addition.
Recommended calculation for trial lens:
power = distance value of contact lens + 50% of addition
Example for distance value -4.50 and addition requirement of +2.00:
power = -4.50 + (+2.00:2 ) = -3.50
