Presbyopia (age-related farsightedness)

Presbyopia, the age-related farsightedness, is the eyes condition when the vision for near objects is deteriorating causing difficulties when reading small prints, especially at poor light and doing any job near-hand.

The causes of presbyopia:

A human being thanks to the crystalline lens ability to change the focal distance (accommodation) can see objects at different distances – both far and near. With age the crystalline lens tends to become more resistent and loses elasticity, therefore the ability to increase flexion to see the objects close to eyes is deteriorating and the eyes accommodation capacity is impaired. Moreover the muscles holding the crystalline lens become weaker with age as well. Therefore when the end-lobes responsible for vision send signals to the eye muscles, the latter are not capable any more to change the crystalline lens shape to focus images of the near objects on the retina. As a result, the person sees blurred and unclear objects.

Presbyopia symptoms:

  • Blurred vision;
  • Difficulties in seeing objects near-by;
  • Difficulties in reading and writing: small prints are soft and fading;
  • When working with small objects the items have to be moved far from eyes;
  • Frequent headaches;
  • Eye fatigue;

IMPORTANT INFORMATION!

  • Too often when first sign of visual problems show up people consider them as minor thing connected with age or fatigue and then they run hazards of eye health. After 50 the body is getting “worn” and prone to various deceases. Vision deterioration may symptom not only presbyopia (age-related hyperopia) but also cataract or retinal disorders, or such endocrine decease as diabetes mellitus. Therefore it is very important to see an ophthalmologist and a physician regularly, and have necessary checks and test.
  • Spectacles should be prescribed after accurate and precise diagnostics and consultations with an ophthalmologist. And it is so important as well to buy spectacles only at specialized opticians shops, rather from general stores or somewhere else. Spectacles are sophisticated gadgets and besides power other important parameters seriously affecting vision quality should be followed precisely during production.
