How to correct hyperopia, myopia and presbyopia? Find out everything you need to know about multifocal contact lenses here!
At a certain age (on average 43 years), there is a good chance that, in addition to a correction to see from a distance, you also need another correction to read. This is due to the fact that from this age, the crystallins present in our eyes do not curl enough to clearly distinguish the images closely. This pathology has a name: presbyopia.
Progressive lenses are then a suitable solution, because they combine the two corrections (to see far and near). They correct both myopia, hyperopia and presbyopia.
Not to be confused with bifocal lenses
Do not confuse multifocal lenses with monovision or bifocal lenses: monovision aims to correct one eye to see from afar and the other eye to see up close. Our brain then automatically uses the eye perceiving the sharpest image.
Bifocal lenses are always rigid and do not have a gradual transition between the correction zone to see from a distance and that to see up close, but have a real correction zone for reading, like bifocals.
See well, at any distance
Do multifocal contact lenses also really offer more visual freedom?
Well, they have many undeniable advantages. You can see better from near, but also from a distance as well as at an intermediate distance. This is due to the fact that the reading area is in the center of the lens and a transition is slow from the center to the area to see well from afar. This transition is very gradual, which allows you to continue to see clearly at all distances.
No more deformations
Do you usually wear progressive glasses? You will quickly notice that with the multifocal lenses, the deformations caused by the glasses are only a bad memory.
Lenses are also more convenient, whether for sports, reading, driving or watching TV.
Multifocal lenses, a question of habit
We sometimes hear people wearing multifocal lenses recently say that this is a matter of habit: it may indeed take a little while before our brain makes the right choice between the sharpness of the images.
Having to get used to several simultaneous images, so to speak, can cause you some vertigo, but this phenomenon disappears quickly.
That is why it is very important to always mention the problems encountered and regularly have your eyes and lenses checked to make any small adjustments to improve your comfort.
