Eye health is often overlooked until problems arise. Conditions like cataracts, glaucoma, and macular degeneration can impair vision and quality of life. Early diagnosis and treatment can prevent or manage damage.
This blog explores common eye issues, their symptoms, and the importance of protecting your vision for lifelong eye health.
Blurry Vision (Refractive Errors)
Refractive errors are the most common cause of blurry vision and occur when the shape of the eye prevents light from focusing correctly on the retina. This can lead to distorted or unclear vision at various distances. These errors affect how clearly we see objects and often result in eye strain, headaches, and difficulty focusing.
Myopia (Nearsightedness)
People with myopia can see close objects clearly but struggle to see things farther away. It’s often noticed in childhood and can worsen with age.
Hyperopia (Farsightedness)
Hyperopia causes difficulty focusing on nearby objects, while distant objects remain clearer. This can lead to tired eyes and trouble reading or doing close-up work.
Astigmatism
Astigmatism results from an irregularly shaped cornea or lens, causing light to focus unevenly. This leads to overall blurry or distorted vision at all distances.
Presbyopia
Presbyopia is an age-related condition that makes it harder to see things up close. It typically begins around age 40 and progresses over time.
Dry Eye Syndrome
Dry eye syndrome occurs when the eyes don’t produce enough tears or when the tears evaporate too quickly, leading to discomfort and vision problems. This condition can make it difficult to perform daily tasks, such as reading or using a computer, and may cause eyes to feel irritated or fatigued.
Common causes of dry eye include ageing, extended screen use, certain medications, hormonal changes, and environmental factors like wind or dry air. Symptoms often include itchiness, redness, a burning sensation, sensitivity to light, and even excessive tearing as the eyes try to compensate for dryness.
Treatment options range from over the counter or prescription eye drops to help maintain moisture, to lifestyle changes such as reducing screen time, taking regular breaks, using a humidifier, and wearing protective eyewear outdoors. In more severe cases, procedures to block tear drainage may be recommended to retain moisture in the eyes.
Cataracts
Cataracts occur when the normally clear lens of the eye becomes cloudy, leading to blurry, dull, or hazy vision. This clouding blocks or scatters light entering the eye, making it harder to see clearly, especially in low-light conditions.
Ageing is the most common cause of cataracts, but other risk factors include prolonged exposure to ultraviolet (UV) light, smoking, diabetes, and certain medications. Symptoms often develop gradually and may include difficulty seeing at night, sensitivity to bright lights or glare, and faded or yellowed colours.
While early cataracts may be managed with stronger glasses or better lighting, the most effective and permanent treatment is cataract surgery. This procedure involves removing the clouded lens and replacing it with a clear artificial one, restoring vision and significantly improving quality of life.
Glaucoma
Glaucoma is a group of eye conditions that damage the optic nerve, often due to increased pressure within the eye. This damage can lead to gradual and irreversible vision loss, making glaucoma a leading cause of blindness worldwide.
Often called the “silent thief of sight,” glaucoma typically develops without noticeable symptoms in its early stages. By the time vision changes are detected, significant and permanent damage may have already occurred.
The most common type is open-angle glaucoma, which progresses slowly and painlessly. In contrast, closed angle glaucoma develops suddenly and is a medical emergency, with symptoms like severe eye pain, nausea, and sudden vision loss.
Early diagnosis through regular eye exams is crucial. Glaucoma treatment options include medicated eye drops to lower eye pressure, laser procedures to improve fluid drainage, and surgical interventions in more advanced cases. While glaucoma cannot be cured, timely treatment can help preserve vision and prevent further damage.
Age Related Macular Degeneration (AMD)
Age-related macular degeneration (AMD) is a common eye condition that affects the macula, the central part of the retina responsible for sharp, straight-ahead vision. As the macula deteriorates, AMD leads to a gradual loss of central vision, making it difficult to read, drive, or recognise faces.
There are two main types of AMD. Dry AMD is the more common form and results from the gradual thinning of the macula over time. Wet AMD is less common but more severe, caused by abnormal blood vessels growing under the retina that can leak fluid or blood, leading to rapid vision loss.
Symptoms of AMD include blurry or distorted central vision, trouble recognising faces, and the appearance of dark or empty spots in the centre of vision. While there is no cure, management strategies include healthy lifestyle changes (like quitting smoking and eating a diet rich in leafy greens), taking specific dietary supplements, and undergoing treatments such as laser therapy for wet AMD. Early detection is key to slowing progression and preserving remaining vision.
Diabetic Retinopathy
Diabetic retinopathy is an eye condition caused by diabetes that damages the blood vessels in the retina, leading to vision problems. Uncontrolled blood sugar levels and long-term diabetes are major risk factors, as they can weaken and distort blood vessels in the retina over time.
Common symptoms include floaters, blurred vision, dark spots, and, in more advanced stages, vision loss. The condition often develops gradually without noticeable symptoms in the early stages, making regular eye exams crucial for early detection.
Treatment options focus on managing blood sugar levels to slow progression, along with laser treatments to reduce swelling and prevent further blood vessel damage. Injectable medications may also be used to control inflammation and help preserve vision. Early intervention can significantly reduce the risk of severe vision loss.
Conjunctivitis
Conjunctivitis, commonly known as pink eye, is an inflammation of the conjunctiva, the thin tissue that lines the eyelid and covers the white part of the eye. It leads to redness, swelling, and discomfort, often accompanied by itching or a gritty feeling in the eye.
There are three main types of conjunctivitis, each with different causes:
- Viral conjunctivitis is usually caused by the same viruses responsible for the common cold and is highly contagious. It often causes watery discharge and may resolve on its own within a week or two.
- Bacterial conjunctivitis produces a thicker, yellow or green discharge and requires antibiotic treatment to prevent complications.
- Allergic conjunctivitis is triggered by allergens like pollen or pet dander and is not contagious. It often causes itching, redness, and watery eyes.
Treatment depends on the cause: viral conjunctivitis typically requires supportive care, allergic conjunctivitis can be managed with antihistamines, and bacterial conjunctivitis often needs antibiotic eye drops. Home remedies, such as warm or cold compresses, can help alleviate symptoms.
