Eyesight is a wondrous thing. Involving complicated underlying functionality and scientific techniques, we often take for granted just how sophisticated vision is. Colors, precision, image sharpness, the focus are just some things that the anatomy of the eye caters too.
Then there is the brain that forms the actual image. From combining the images received from both eyes to properly inverting them, our brain also plays a crucial role in our ability to see.
The mesmerizing harmony between the brain and eyes is what constitutes vision. Understanding what precisely vision helps in not just understanding but also appreciating the human body.
The major roles in the eyes are played by; cornea, which helps in focusing light, iris, and pupil that control the light entering the eyes, a lens that focuses the light onto the retina which in turn sends signals to the brain via the optic nerve. The image is then formed as the brain combines the vision from both eyes, superimposes, and inverts it. Tear ducts eye the eyes moist and free of the debris.
Any problem with these important components of the eyes then has the person running to the Best Eye specialist in Islamabad.
What are conditions that affect vision?
Our vision is influenced by a wide range of factors. These include:
Beyond our control and unavoidable are the age-related problems. These occur due to the age-induced degeneration in the eyes and also because of the diseases that become more common in old age.
Examples include farsightedness, age-related macular degeneration, cataracts, etc.
Diet and vision have an interesting relationship. Whereas a good diet helps in preserving vision, a bad diet harms it, leading to problems like macular degeneration.
Eating well also helps in delaying the progression of certain eye diseases like cataracts.
While some eye diseases are due to our lifestyle choices, many however are due to genetics and similar incorrigible factors. Similarly, eyes are also susceptible to infections that can affect vision as well.
Many injuries to the eye can also lead to vision problems. One such case is the detachment of the retina, thereby causing vision loss.
When the light is not focused properly on the retina, vision gets compromised. Nearsightedness results in the inability to see far off objects, whereas farsightedness is the converse of the condition. The lack of focus results from the changes to the lens in the eyes.
How to keep your vision healthy?
While some of the conditions affecting the eye are beyond our control, we can still take steps to retain our good visions. Healthy practices to be incorporated include:
Natural foods are good for the physical health generally, and vision in particular. There are certain nutrients that are more helpful towards the vision. Vitamin C is great for preventing cataracts and also helps in decreasing the progression of diseases like AMD. It is found in abundance in oranges, lemons, and berries.
Lutein and Zeaxanthin are antioxidants found in green leafy vegetables. They help in averting the risk of chronic eye diseases. Moreover, omega-3 and 6 fatty acids are also useful for preserving vision. Another useful nutrient is Zinc, which helps in the utilization of vitamin A by the eye.
Similarly, vitamin E is vital for the eyes as it is an important antioxidant that protects the eyes against free radicals. Good sources of vitamin E include almonds, peanuts, mango, avocado. When taken in conjunction with the other aforementioned nutrients, it helps slow the progression of AMD.
Stay out of the sun:
Sunlight is full of ultraviolet radiation that is dangerous to the eyes and the skin. Therefore, it is best to avoid exposure to sunlight and wearing sunglasses where possible.
Take up exercise:
Exercise is great for improving circulation around the body. As the eyes get a better blood supply, they are better able to unload the toxins and also get nutrients more often that vitalizes the cells.
Smoking is never a good idea. It affects all the organs, and the eyes are no exception. It contains dangerous chemicals that lead to chronic diseases like age-related macular degeneration and cataracts, the former being a permanent loss in central vision.
Therefore, quit your habit of smoking immediately.
It is best to stay informed of your eye health. Many conditions like AMD do not present with symptoms in the initial phases of the disease and become apparent only when the vision loss becomes more profound.
Regular checkups also allow for early diagnosis of the disease and thus aid in a better prognosis. So, do make a habit of frequenting your Eye specialist in Lahore.
