Sight is a supreme necessity.A rooted concept, but it's a well habit to be repeated.
The thing we often ignore, is that there are many phases in our eyes' life that request all our attention just because we usually give them an inadequate importance.
In the age from three to twenty years it is always suitable to recommend repeated visual check -ups because we are in a period in which eyes compromising is high and the most common visual defects can increase . As, for example, short-sightening.
Short-sightening, as the most common visual defects , as astigmatism and farsightedness, oblige to wear glasses or contact lenses.
Furthermore,the third decade of life ( sometimes also before) is characterized by starting of keratoconus. Kerathoconus is a pathology that affects every year 50 people on 100.000 and it is a desease linked to a structural weakness of cornea that progressivley tends to tire out slowly, assuming the shape of a cone.
In this case therapy foresees the use of special glasses, named aberrometric, and particular kind of contact lenses.
Until some time ago, the alternative in some difficult cases was cornea transplant , today we have the possibility of supplying a laser therapy, called cross linking that allows to reinforce the cornea structure.
So, it is fundamental to make eye visit if vision becomes out of focus , if we have difficulties in seeing far or near and if symptoms like burning sensation , or of foreign body , or excessive tearing appear. Check-ups will become yearly if in presence of clear visual athologies or defects , every two/ three years in absence of symptoms.

They warned that this has the potential to fog the line between actuality and fantasy, peradventure damaging relationships and encouraging harmful behaviour.
But what does the evidence absolutely reveal hither how porn may or may not be affecting people? Can research stipulate any answers?

The nature of porn dictates that researchers must either rely on people self-reporting their porn habits, or show it to them in laboratory settings that are unnatural. (And no uncertainty, slight oafish, too.)
That said, there is a growing masses of literature that can lend hints. BBC Later reviewed what researchers have concluded so far.
