Presbyopia (vision after 40)
At about the age of 40-45 the lens in the eye looses its flexibility, and accommodation is gradually lost. This is a normal change that everyone will experience.
Early signs of presbyopia can include headaches, tired or sore eyes when reading, the need to have better lighting for close work and difficulty seeing fine print or small objects.
Presbyopia is corrected with spectacles, which may make your long distance vision blurry. You may like to have a small pair of spectacles, which you can look over the top of to see in the distance or a pair of progressives which are designed to give you clear vision at all distances.
