What is Presbyopia?
Presbyopia is the gradual loss of vision when focusing on near objects. Blurry vision is more occasional at the start of presbyopia, fluctuating, depending on tiredness, light conditions, the tasks being carried out at close distance, etc. You might notice that you can't focus well on near objects, but when you move away (for example when looking at an electronic device) focus improves. It is more difficult to focus at night, when you are tired or in low light conditions. Other symptoms include tired eyes, itching and headaches.
As presbyopia increases, the ability to focus decreases, because the blurry vision is constant, which can also affect medium distances.
Vision with Presbyopia
Presbyopia is caused by hardening of the eye’s lens, which happens due to ageing. The lens is slightly flexible, and changes shape with the help of the circular muscle that surrounds it to focus on images. In other words, when looking at something far away, the muscle relaxes, and it contracts when looking at something near.
How many people are affected by presbyopia?
80% of the population in Europe has presbyopia. Presbyopia progresses with age. It usually starts around 40-45 years, and tends to stabilise around 60-65 years.
