Cataracts are caused by an accumulation of damaged proteins in the eye, namely the cornea, which eventually sight because they are opaque and do not allow light to pass easily. It is an accumulation that occurs in most cases over the years and eventually leave us a view of poor quality, because we can barely distinguish objects clearly.
Over the years, our body undergoes many changes and many eventually worsen our health. An example are the falls that many people suffer when they reach adulthood. It is a problem that worsens our quality of life, but it can be prevented.
Despite this we know that cataracts can be prevented by tracking healthy habits. But first we have to know the reasons that make our body to develop the disease or disorder remains our vision. In most cases cataracts occur with the passage of time and accumulation of these proteins, but other reasons.

Falls are displayed in the newborn soon after birth. They are not linked to age, and its source type:
Genetic: are linked to autosomal dominant genes. This means that it is only necessary for a parent to transmit the gene for this to manifest, which increases the probability of occurrence of the disease in the neonate from a family where one parent has the gene to 50%.
Infectious: certain infections suffered by the mother during pregnancy can cause the appearance of visual disorders in the fetus, including congenital cataracts you. One such disease is larubéola.
Metabolic: galactosemia, diabetes, etc.
In pediatric patients the diagnosis and early treatment, because cataracts delay the correct development of vision and can lead to amblyopia (lazy eye) is especially important.
- Immature Cataracts are cataracts that come with age, characterized in that the lens still retains its transparency in certain areas.
- Mature Falls: as immature cataracts occur with age and are characterized by the lens has completely lost its transparency.
- Hypermature Cataracts are the maximum state of chronicity of the falls appeared with age. Lens, besides having completely lost its transparency, has a liquid surface, which is filtered through the capsule of the eye, and may cause inflammation of other structures of the eye.
Causes of Cataracts
The causative factors of cataracts in adults are varied and different for each person:
- Environmental factors: smoking, excessive exposure to ultraviolet light or other aggressive radiation and ocular trauma (blows to the eyes) are factors closely linked to cataracts.
- Metabolic factors: are mainly the presence of diabetes in the subject and low levels of serum calcium. They are also associated with other metabolic and inflammatory disorders.
- medicated factors: it has found a direct relationship with the use of certain drugs, highlighting markedly corticosteroids (cortisone and its derivatives).
