An eyes desease that compromises progressively and slowly the sight. Very often, glaucoma does not cause symptoms and you notice of being affected only when it's too late. Fortunately, a premature diagnosis and the right therapies, can stop the evolution of this desease and reduce the damages at their minimum.

In Italy, about two millions of people are affected by glaucoma, a pathology distinguished by the increase of intra-ocular pressure 

Within the eyeball del bulbo oculare, it flows a liquid, so called  umor aqueo : its function is to "nourish" eye structure. it circulates continuosly within the eyeball pouring out through dedicated ways ; when these flowing ways obstruct, the link between umor aqueo produced and the one leimaed, it grows , and, as a consequence, the pressure qithin eyeball increases.

If this increase is high, or for too long, it can damage the optic nerve.

This leads to a progressive reduction of visual field, that, at the beginning, it affects only side vision, and, if it's not soon treated, can compromise once for all the sight.

Glaucoma affects above all people over 40s and its incidence, grows with growing of age . Further risking factors are represented by some deseases as ocular hypertension, short-sightedness, diabetis, and, last but not least, cases of familiarity pathology.

All glaucoma cases,  except the inborn species, are preventibles. For thsi reason, the premature prevention is fundamental . Though a simple eye exam, infact, it is possible to intervene in time to stop or to delimit the desease progression, before that permanent damages occurr.

For thsi reason, over forties, it is suggested to undergo to eye exam at least once every 2 years.

How many times we have experienced of being dazzled by a bundle of light ,above all whan we are driving? To reduce this fastidious dazzling it's possible, thanks to particular kind of lenses  that, besides protecting against Uv rays,reduce in a significant way the dazzling bother.

But, what is striclty, the dazzling? It represents the difficuly of seeing in conditions of strong lighting , as for expample direct sunlight, above all when we drive. In effect, the high intensity of light bundles can be very fastidious because the pupil reacts to it, and, particularly, to the kind of light that hits direclty the eye.

Basically, the dazzling can be dangerous because it reduces the visibility of objects and sensibility of contrast. For people who wish a relaxed vision to enjoy at its best the sun, and, at the same time, eliminate small botherings induced by dazzling, it is necessary to use a polarized lens.

Hereinafter, six motivations that summarize the advantages of using a pair of sunglasses with polarized lenes:

1) relaxed vision, with less eye fatiguing

2) a better definition of images due to a greater contrast and correct perception of colors

3) 100% UV protection

4) avoidance of fastidious bright waves 

5) reduction of dashboard reflex when driving

6) growth of contrast and visual comfort in general

Our body is a machine and it functions through energy that goes around our body by means of electric and magnetic waves: such energy is used for the functioning of our sensorial organs, above all eyes . Since early morning, when we wake up ,we use our eyes as a primarly sensorial organ . During sleep time also, they are in constant moving , infact, at the end of the day we feel tired and fatigued .Our eyes consume a great portion of our total energy and, in case of stress increases we tend to consume a portion greater than the necessity.

Over the half of energic nourishing is given by tears, so, it is good to always maintain a high level of lubrication to sustain  the daily nourishing and avoid dryness that brings to eyes fatigue.

The problem of eyes dryness is important and it cannot be underevaluated, if you are interested, discover how to reduce and prevent this problem.

First of all, try to discover the causes of nourishing deficit of the eye. As we already repeated  previously the main source of nurturing is given by tears. They tend to be originated in the upper part of cornea and eye conjunctiva. The so-called lacrimal glands have unqiue characterics : they are wrapped with a layer of surface fat that impedes evaporation of the wide water part , and with a proteic layer of slime, that is an adhesive substance that allows to maintain opticaml adherence of eye surface , besides allocating water molecules through cellular membrane. So, the cause of ocular dryness is found in lacrimal film.

How can we find a solution?

Through little expedients that can literally make the difference, but it is also useful to premise that ocular dryness cannot be cured in compelte way. Anyway, try to:

- Not expose eyes directly to air jet, as phon or car heating 

- Protect your eyes from solar rays exposure using correct filters anti-UV

- Nictate more frequently , this will contribute to tears production 

- Do not rub your eyes so much .

Starting from the assumption that an efficient treatment for ocular dryness  requests eye doctor intervention to make an attentive test and determine the provoking cause of the preposed symptoms, it is a good habit to maintain the eye fresh and wet. To this purpose the range of products   Opto X (http://www.optox.it/), from OPTOyal A to OPTOsol, each one of them is  suitable to saisfy the different typologies of needs, from fatigue to the more marked dryness, from redness to blepharitis.

In each case, it is sggested to maintain an hydration level that is generally elevated. So ,starting from basis, try to drink more wated and to reduce the use of salt in your daily diet.
