MYOPIA, HYPERMETROPIA, ASTIGMATISM
These are refractive defects of the sight which appear in the developing years of the individual. They can be corrected with glasses, contact lenses or laser treatment depending on the age of the individual.(+information)

PRESBYOPIA
Commonly known as eyestrain, this is the inability to focus on nearby objects and affects the individual due to the failure of the accommodation function of the crystalline lens. It appears from the age of 40 onwards and can be corrected with glasses or by laser.(+information)

CATARACTS
This is the stage following presbyopia in the progressive degeneration of the crystalline lens and refers to the loss of transparency or alteration in light conduction. It can be corrected by replacing the crystalline lens through surgery.(+information)

GLAUCOMA
This is the atrophy or death of the cells of the optic nerve and retina as a result of an increase in intraocular pressure. It can only be prevented by means of early diagnosis with regular ophthalmological check-ups. Once diagnosed, it can be treated effectively with drops, by laser or with surgery depending on the severity of the case. (+information)

MACULAR DISEASE OF THE RETINA
These are the group of diseases that affect the macula. The macula is the area of the retina charged with focussing the retinal image and containing the majority of the chromatic photoreceptors of the retina. It is where the human eye achieves maximum image resolution.
It consists of a degenerative disease which affects the central area of the retina: the macula, responsible for central vision. There are two types of AMD: Wet and Dry. The majority of people present the “dry” form of macular degeneration. This is caused by age and the thinning of the macular tissues. Sight loss is generally gradual.
AMD does not cause any type of pain, and may therefore go unnoticed in its initial phases. On occasion, when just one eye is affected, the symptoms may not be noticed until the second eye becomes affected. The symptoms can vary depending on the person affected, but generally there is a distortion of straight lines, which appear to become curved or twisted.
The central part of the vision may also appear blurry, with a dark shadow in the centre.
Wet AMD appears when there is a proliferation of anomalous blood vessels in the macula, damaging it and causing severe and irreversible loss of central vision. (+information)
