Why can't I see clearly with my new near glasses on the computer?

Many presbyopes notice that the range of clear vision decreases more and more each time, having increased the degrees, they replace the lenses. So, with the new glasses, they may see clearly at very close distances, e.g. their cell phone, but at the same time they lose intermediate distances, e.g. the computer.

Cause: the above condition is normal, and occurs when presbyopia increases (usually after 1.75 diopters). So the presbyope needs more enhanced points to see near e.g. on mobile, but at the same time more relaxed to see at medium distances, e.g. on his computer.

Solution: so instead of using two near glasses - one for the very near, and one for the PC - and alternating them every time, the solution comes with the advanced medium-near eye lenses. In these lenses, the intensity of the degrees increases towards the lower parts of the lens, from where we look at very close objects, and progressively relaxes upwards, from where we look at medium objects within one meter.

Cost of medium close lenses ≈150-180€

*In the aesthetic part, in terms of appearance, the progressive gradation of grades is not visible, and is not perceived by a third party.
