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

Many presbyopes notice that their clear vision decreases more and more each time they replace their lenses, having increased their prescription. 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.
Reason : the above condition is normal, and appears when presbyopia increases (usually after 1.75 diopters). Therefore, the presbyopic person needs more enhanced powers to see up close, e.g. on a mobile phone, but at the same time more relaxed powers to see at medium distances, e.g. on his computer.Solution : Instead of using two near-sighted glasses - one for very close-up, and one for the computer - and alternating them each time, the solution comes with advanced intermediate-near-sighted 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 towards the top, from where we look at medium-distance objects within one meter.
Cost of medium-near lenses ≈290€
*In terms of aesthetics, in terms of appearance, the progressive gradation of the grades is not visible, and is not perceived by a third party.
