Structure, Function, and disease of the eye

The source that view outside world requires considerate care

Hey is it not true that if sometimes your vision gets blurred then you opt for spectacles but you don’t consider it as a major problem. An accurate eye vision of a person is as important as mapping out a strategic future plan for a strong future by him/her especially in today's times where uncertainties prevail unknowingly at every step in life. The preciousness of eyes is immeasurable because through them humans can view the glinting images of objects and see the world. Tainted surroundings with arising pollution levels might have distorted the vision of millions of people but the importance of eyes is better known to a blind man.

Years after years, deterioration of the environment seems to uphill and so the eyes have also felt its long-lasting effects. But continuous ignorance by the government and constant negligence displayed from the side of people alter the fact that a perfect vision comes from considerate caring which has gone missing. It isn't a mind-boggling fact to witness that a large section of these people could be cured but remain unaware and in most cases find eye-treatments to be more costly.

Haven't you been tired of hearing the line "Prevention is better than cure" and ever wondered if so then why these many people didn't get rid of eye-cataract before? Its answers lie in lack of awareness among them and slightly indicate the immediate need for up-gradation of rural hospitals and sudden need to equip them with regular-eye examiners.

Remember the last time when you fixed your eye-glances to gather information about eye-structure, probably when you were in school and needed to go through the examination.

Structure of Eye

Cornea

The cornea is the outer front window of the eye that transmits and focuses light in our eye. Patients suffering from eye-problems are advised for corrective laser surgery that reshapes the cornea by changing its focus.

Iris

Iris is that organ of the eye which fixes the amount of light residing in the eye. At times of sudden emergence of bright light, Iris closes the pupil for letting it in low light. In contrast to low-light, it allows the pupil to pop-up to allow more light to come in.

Lens

Lens help light-rays to fall on the retina as they are transparent. With their transparency comes an option of replacement that generally happens when people age. Besides aging, a cluster of cataract clouds the lenses and replaced by Intraocular lenses.

Optic Nerve

The transportation of visual messages from the retina to the brain is possible through the optic nerve. Comprising of more than a million nerve fibers, it controls visualization of the brain because it amalgamates images. Since upside-down images are seen controlled through retina whereas the brains visualize images right-side up.

Diseases of the eye

It is an actual fact that blurry vision permeates darkness which further affects the cornea, pupil, iris, and retina and weakens the eye-sight. It further gives propagation of eye-diseases like Age-Related Macular Degeneration, Glaucoma, Keratoconus, Eye-flashes, and many more whose effects are life-long and require immediate treatment to counter their effect.

Could have anybody believed that even babies do become prey to the eye- cataract disease? No signs of early symptoms allow parents to think about it as a common problem but with the passage of time, these diseases become quite advanced.

It is observed that the medical-treatments in India have become more feasible and stirred a wave of awareness among people to seek a medical-practitioner even while they suffer a minute pain in any area of the body. Following it lies a record that talks about the rising number of people turning to professional-eye-examiners to keep a thorough check on their eye-sight.

Age-Related Macular Degeneration

With the onset of aging comes many dilemmas that obstruct the way of living for many of us. It is generally conceived that a person owing a strong vision in his adult-phase couldn't require spectacles to view in his retiring years. Unfortunately, this myth has also fragmented because of the changing climatic conditions that have begun stressing the eyelids of people. Like its name, this eye-disease occurs during late-years of a person's life as he/she has already consumed nourishment that spring of life offered to them in their early days.

Loss of central vision, visual hallucinations or complete blindness.

Affecting Factors of AMD

Excessive smoking damages retina that worsens contrast sensitivity and propagates distorted vision.

Hypertension also adds to AMD and it is evident from the study of ALIENOR 2013, it is found that high blood pressure mounts a higher risk of late AMD.

Glaucoma

This occurs at any age, this disease germinates through abnormally high pressure in the eyes. Stressing of eyes while viewing smart-gadgets propagate eye-redness among kids as their age is naïve and pain at this stage affects temporarily. Later it advances and lets pain turn more sharp at the optic nerve. This is the reason why several doctors suggest people spend some time off from technologically enabled devices and deviate themselves from a monotonous work cycle by preferring yoga-related practices.

Aqueous humor often responsible for producing elevated eye-pressure also flows across all the parts leading to the deteriorated vision among people. This internal fluid passes through trabecular meshwork that is formed at the angle where the conjunction of Iris and cornea happens. Eye-pressure increases when it is over-produced or it can't pass at a normal rate.

Factors Affecting Glaucoma

If a person surpasses the age-limit of 60 then Glaucoma tends to create its home at his/her eyes.

Family History

However, assumptions formed on scientific grounds suggest that genetic factors contribute to determining the heritance of traits. This synchronizes with the fact that people having a family history of suffering from Primary Open Angle Glaucoma is more prone to this disease.

It is a gospel truth that emergencies never wait for a certain time to arrive when they arrive either they devastate the health of a person or kill his will-power to outperform certain things. This is a reason why affirmation or even inconsequential consequences necessitate sudden anticipation to rescue oneself from the clutches of the deadly disease.
