Why eye health is important

Eye health is essential to enjoying a good quality of life. Here, we explain what factors you need to bear in mind to enjoy good visual health.

To ensure good visual health, it is important to acquire healthy habits, including moderate exercise, a diet rich in antioxidants and Omega 3 and regular eye tests, the frequency of which depends on age, general health, personal or family history of eye diseases and personal circumstances and visual needs.

A good ophthalmic and optometric examination will enable early diagnosis of eye diseases that can progress without symptoms and the discovery of the onset of or increase in refractive errors or other visual problems. This is particularly important in certain population groups who should have their vision checked regularly.

Eye tests by age group

  • After birth to rule out congenital abnormalities such as glaucoma or congenital cataracts, malformations, tumours, congenital strabismus, congenital ptosis.
  • At 3-4 years, a complete eye examination should be performed: visual acuity (lazy eye), ocular motility (strabismus), optical power with drops, fundus.
  • Between 4 and 10 years: annual eye examination to monitor the development of the visual system.
  • Between 10 and 16 years: eye examination every two years.
  • From 50 years: ophthalmic tests every two years including: visual acuity, far and near vision, intraocular pressure, assessment of the anterior pole, fundus and optic nerve. These tests can help detect incipient glaucoma and AMD, provide patients with advice on the management of cataracts and improve quality of life in relation to presbyopia.
  • At any age: it is advisable for patients to have annual eye tests if they have refractive errors (especially high myopia), diabetes, hypercholesterolemia, vascular problems or a history of eye disease.
