How do the eyes work?
The eye is one of the most sensitive and sophisticated organs in the human body. All the different parts of your eyes work together to help you see. First, light passes through the cornea (the clear front layer of the eye). The cornea is shaped like a dome and bends light to help the eye focus.
Some of this light enters the eye through an opening called the pupil (the black dot in the middle of the eye). The amount of light that enters the eye is controlled by the iris (the colored part of the eye).
With age, the cornea has a tendency of becoming clouded and blurs the vision, a condition commonly known as cataract. If you’re above 50 and experience blurring of vision, get it evaluated by an eye specialist. Find a physician online or connect with a specialist at My live doctors. Online health services like My live doctors don’t only help you connect to a physician online quicker but it’s cheaper too.
Next, light passes through the lens (a clear inner part of the eye). When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals which travel from the retina through the optic nerve to the brain. Then the brain turns the signals into the images you see!
What causes weak eyesight?
Different eye diseases or conditions can lead to poor vision. Some common eye problems are:
- Glaucoma. This condition occurs when there is an increase in internal pressure in the eye because of problems with the flow or drainage of fluid within the eye or when there isn’t enough blood flow to the optic nerve. The optic nerve is responsible for vision, so when it is damaged, it results in poor vision.
- Macular degeneration. The macula is the area on the retina responsible for sharp central vision. Macular degeneration affects the retina, (the light sensitive part of the eye responsible for focusing images) as well as the macula. It may cause a ‘blind spot’ or blurry vision.
- Cataract. Cataract is the clouding of part or whole lens inside the eye which interferes with light reaching the retina at the back of the eye resulting in blurry vision. Aging is the most common cause of cataract formation.

Other conditions include:
- Diabetic retinopathy. This condition is a complication of long-standing diabetes. In diabetes, tiny blood vessels that supply the retina are affected causing gradual changes in vision and damage to the retina.
- Retinitis pigmentosa. This condition affects night vision. Night blindness is often the first symptoms and begins in childhood or early adolescence.
- Amblyopia. The visual system fails to develop normally during childhood in amblyopia.
- Retinopathy of prematurity. This condition occurs in newborns if they are exposed to high levels of oxygen in incubators during the neonatal period.
- Retinal detachment. When the retina separates from the underlying area it can cause total vision loss.
- Brain injury. Head injuries, brain damage and stroke can lead to poor and deteriorating eyesight.
All brain or head injuries should be examined in a clinical setting. If you are unable to reach a medical facility immediately you can talk to a physician online at My live doctors and receive guidance on immediate care until you are able to get to a hospital.
If you or a loved one falls in to one or more of the above categories, see your doctor. Or at least talk to one about the symptoms you may be experiencing. Besides blurring of vision, many people complain of headaches and dizziness too. Kids might complain of not being able to see the board clearly at school. Get expert medical advice from home. Find a physician online and get answers. An informed patient is able to make better decisions.
How to improve your eyesight?
Here are a couple of way you can improve and protect your eyesight naturally!
- Depending on the activity, wearing protective eyewear can help prevent injury, damage, and irritation to eyes from impacts, debris, and chemicals. For instance, safety glasses, visors, goggles and helmets should be worn when required.
- Excessive UV exposure from sunlight may increase your chances of getting cataract and eye cancer. Wear sunglasses for protection when you go out and avoid looking at the sun directly.
- Remember to take regular screen breaks while working on the computer or using a cell phone.
- If you’re diabetic, controlling your blood sugar levels are crucial to preventing diabetes related vision complications.
- Studies show that in people aged 65 and above, people with poor eyesight also have a chronic condition like diabetes, hypertension, heart disease, high blood cholesterol, arthritis, asthma and depression. Find a physician online who can help you monitor your chronic health condition remotely. Schedule regular follow-ups online and keep your health on track.
- ‘Feed your eyes’ by taking eye-healthy vitamins like A, E and C. Good sources of these vitamins include carrots, broccoli, spinach, sweet potato, almonds and peanut butter.
