Multifocals are designed to address presbyopia, a condition that typically occurs as people age and their eyes lose the ability to focus on close objects. ALWAYS remember, multifocals are made for people with two eyes who have reasonably good vision in both eyes. The two eyes need to be working together as a team so as to point accurately at the same object in free space. If there is any underlying binocular vision problems, it will affect the patient’s ability to work comfortably with their multifocals. If you only have one eye, always remember that you need to be very aware of the distortion that the multifocal creates as you become older. ( Watch my video on the Minkwich law) Also bear in mind that if you only have one dominant or good eye, you will always hold a book or mobile phone in that hand that corresponds to that dominant eye. Basically, if your right eye is your only eye that you’re seeing with, if , you then hold object an your left hand, your nose would partially be blocking your view. ( or , the minimum, be obstructing/ interfering with your vision ) If your right eye is doing all the work, then you would most probably always hold the object that you’re looking at in your right hand as well. Most often we would also find patients that are myopic - especially if they have some astigmatism, and has been wearing glasses from a reasonably young age - We find that they adapt easily to their new multifocals. What type of patients do we find struggle the most with their multifocals ? If you have had normal to good vision your whole life, or if you have been slightly farsighted or longsighted , then you might be one of those patients who find it difficult to adapt to their multifocals - Especially as you get older. Why is this ? Well, simply put you have had exceptionally good vision without distortion your whole life. Your brain has basically learned that there is no visual distortion in your world. Unfortunately, all multifocal lenses have some distortion in them, and this distortion in your multifocal lenses just becomes progressively worse as you get older. In general people that are the short sighted, or , myopic have learnt to interpret and become used to a slightly fuzzy world. Unfortunately, the opposite occurs when you are longsighted or have had really good vision when you were younger. Your vision changes when you become older and firstly you have to get used to possibly some reading glasses and then eventually you might have to get used to some bifocals or multifocals. All these lenses , especially multifocals, introduces distortion into your visual world and, often, this is the first time that you brain is faced with a visual environment or visual images that has distortion in them. For many people that is long sighted or had exceptionally good vision when they were young- This visual distortion when they get old , they just find this really difficult to accept and adapt to. One of the things I often mention to my patients is, if they previously tried multifocals and did not get used to them, that we seldom have a better alternative.. it’s rather a question of the lesser of the evils… And finding a golden midway between comfort, practicality and distortion acceptance…. Most often when I explain the problem to my patient, we find a working solution that they are happy to try out and most often, our solution works extremely well. If the right type of multifocal is given to the right patient and everything is done right, including, the prescription ,the measurements, the lens design and the frame selection, then multifocals works extremely well for 99.9% of patients. #jjvanzyloptometrists #adaptability #eye #jjvanzyl #shortsighted #optometrist #myopia #somersetwest #eyeball #Multfocal #spectacles #ProgressiveLenses #PAL #Distortion #LensDistortion #MultifocalLensDistortion #MultifocalProblems #ProblemsWithMultifocal #MultifocalMakeMeDizzy #Multifocals #VisionCare #Optometry #Presbyopia #EyeHealth #BifocalsVsMultifocals #GlassesForAgingEyes #BinocularVision #Astigmatism #Myopia #Farsightedness #VisualDistortion #OpticalLenses #EyeConditions #VisionCorrection #EyeglassPrescription #EyewearForAllAges #MultifocalAdaptation #HealthyEyes #ComfortableVision #LifelongVision #ProfessionalOptometry #OpticalAdvice #MultifocalSuccess
