Common Eye Symptoms You Shouldn’t Ignore
Your eyes are sensitive and complex organs that often provide early clues about changes in your general health. While many mild irritations resolve on their own, certain symptoms may indicate a more serious condition that needs professional attention. Recognising these signs early can help protect your vision and prevent complications.
1. Sudden Vision Loss or Blurring
A sudden drop in vision, even if temporary, should always be treated as an emergency. Possible causes include retinal detachment, vascular blockage, or other acute conditions that need immediate evaluation.
2. Flashes of Light or a Sudden Increase in Floaters
Seeing new flashes or a sudden shower of floaters (small dark spots or shapes) can signal changes in the retina or vitreous gel inside the eye. These symptoms should be checked promptly to rule out retinal tears or detachment.
3. Eye Pain or Severe Redness
Persistent pain, redness, or light sensitivity can be associated with conditions such as uveitis, acute glaucoma, or corneal infection. Professional examination is important to determine the cause and prevent lasting effects.
4. Gradual Loss of Peripheral Vision
If you notice narrowing of your visual field or bump into objects at the sides, it may suggest glaucoma, which can progress silently over time. Regular comprehensive eye examinations help detect this condition early.
5. Double Vision or Distorted Vision
Seeing double or noticing distortion in straight lines may relate to eye-muscle imbalance, neurological causes, or macular disease. These symptoms should be evaluated by an eye-care professional.
6. Persistent Watery or Gritty Eyes
Ongoing tearing, burning, or grittiness may indicate dry-eye disease or a problem with tear drainage. Appropriate treatment can usually improve comfort and vision quality.
When to Seek Advice
If you experience any of these symptoms, or any sudden or unexplained change in your vision, it is advisable to seek professional evaluation. Early attention can help maintain healthy eyes and clear vision.

Dry Eye
Dry Eye Syndrome is one of the most common reasons people visit eye care professionals. While it may sound minor, persistent dryness can significantly affect comfort, vision, and overall quality of life.
What is Dry Eye Syndrome?
Dry eye occurs when your eyes don’t produce enough tears, or when the quality of your tears is poor. Tears are essential for lubricating the surface of the eye, protecting against infection, and ensuring clear vision.
Common Causes
Several factors can contribute to dry eye, including:
Ageing – Tear production naturally decreases with age.
Screen time – Extended computer or phone use can reduce blinking, leading to dryness.
Medications – Certain antihistamines, antidepressants, and blood pressure tablets may worsen symptoms.
Medical conditions – Autoimmune conditions such as rheumatoid arthritis or thyroid disease.
Environmental factors – Dry air, wind, and air conditioning can all increase evaporation of tears.
Symptoms to Look Out For
People with dry eye may notice:
A gritty or sandy feeling in the eyes
Burning, stinging, or itching
Redness
Blurred vision that improves with blinking
Sensitivity to light
Diagnosis and Treatment
An ophthalmologist can diagnose dry eye through a comprehensive eye examination. Depending on the cause, treatment may include:
Artificial tears or lubricating eye drops
Prescription medication to improve tear quality or reduce inflammation
Punctal plugs to slow tear drainage
Adjustments to medications contributing to dryness
Lifestyle changes such as taking breaks from screens, using a humidifier, or wearing wraparound sunglasses outdoors
Why It Matters
Dry eye is more than just a nuisance — if left untreated, it can cause damage to the surface of the eye and increase the risk of infection. Early diagnosis and appropriate management can greatly improve comfort and protect vision.

Glaucoma and vision loss
Glaucoma is often called the “silent thief of sight” because it can cause irreversible vision loss before any symptoms appear. This condition gradually damages the optic nerve, which connects the eye to the brain, leading to peripheral vision loss that often goes unnoticed until it becomes severe.
The most common type, open-angle glaucoma, progresses slowly and painlessly. There are no early warning signs, as the brain compensates for blind spots until significant damage occurs. By the time a person notices changes in vision, the disease is often in an advanced stage, with permanent vision loss.
The best way to prevent blindness from glaucoma is through regular eye exams, especially for those over 40 or with risk factors like family history, high eye pressure, or diabetes. Early detection and treatment with eye drops, laser therapy, or surgery can slow or stop the progression, preserving sight.
Since glaucoma damage cannot be reversed, proactive screening is essential. Get your eyes checked regularly to protect your vision.

Cataracts 101: When to consider surgery and what to expect
Cataracts are one of the most common causes of vision impairment, especially in older adults. Fortunately, cataract surgery is a safe and effective treatment that can restore clear vision. But how do you know when it’s time to consider surgery? This guide explains what cataracts are, their symptoms, and when surgical intervention is necessary.
What Are Cataracts?
A cataract is the clouding of the eye’s natural lens, which leads to blurry or hazy vision. This occurs when proteins in the lens break down and clump together, preventing light from passing through properly. Over time, cataracts can worsen, affecting daily activities such as reading, driving, and recognizing faces.
Common Symptoms of Cataracts
• Blurry, cloudy, or dim vision
• Increased sensitivity to light and glare, especially at night
• Colors appearing faded or yellowed
• Difficulty reading or seeing fine details
• Frequent changes in glasses or contact lens prescriptions
• Double vision in one eye
Cataracts develop gradually, and early symptoms may not be noticeable. However, as they progress, they can significantly impact vision and quality of life.
Causes and Risk Factors
Cataracts are most commonly associated with aging, but several other factors can contribute to their development:
• Age, particularly those over 60
• Prolonged exposure to ultraviolet (UV) light
• Smoking and excessive alcohol consumption
• Diabetes and other systemic health conditions
• Long-term use of corticosteroids
• Previous eye injuries or surgeries
• Family history of cataracts
When to Consider Cataract Surgery
Not all cataracts require immediate surgery. However, an ophthalmologist may recommend surgery if:
• Vision impairment significantly affects daily activities such as reading, working, or driving
• Prescription glasses or contact lenses no longer improve vision
• Glare and light sensitivity make it difficult to drive at night
• There is an increased risk of falls or accidents due to poor vision
If cataracts are interfering with daily life, scheduling a consultation with an ophthalmologist can help determine the best course of action.
What to Expect from Cataract Surgery
Cataract surgery is a minimally invasive outpatient procedure in which the clouded lens is replaced with an artificial intraocular lens (IOL).
The Procedure
• Pre-Surgery Preparation: The eye is numbed with local anesthesia, and the pupil is dilated.
• Lens Removal: A small incision is made in the cornea, and ultrasound technology is used to break up and remove the cataract.
• Artificial Lens Implantation: A clear intraocular lens is inserted to replace the natural lens.
• Quick Recovery: The procedure takes about 10 to 20 minutes, and patients typically go home the same day.
Recovery Timeline (for majority of patients)
• First 24 hours – Some mild discomfort and blurry vision, which is normal.
• First few days – Vision starts improving, but patients should avoid rubbing the eye.
• One to two weeks – Most healing occurs, though strenuous activities should be avoided.
• Four to six weeks – Full recovery is typically achieved, and vision stabilizes.
Life After Cataract Surgery
Most patients experience significantly improved vision within a few days. Some individuals may no longer need glasses for distance vision, while others might still require reading glasses depending on the type of lens implant used.
Cataracts do not return after surgery. However, some patients may develop a condition known as posterior capsule opacification, sometimes called a “secondary cataract.” This can be easily treated with a simple laser procedure known as YAG laser capsulotomy, which restores clear vision within minutes.
Conclusion
Cataracts are a natural part of aging, but they do not have to impact quality of life. If symptoms are interfering with daily activities, cataract surgery is a safe and effective solution that can restore clear vision. Early diagnosis and treatment can prevent complications and improve long-term visual outcomes.
For those experiencing vision changes or cataract symptoms, scheduling an eye exam with an ophthalmologist is the best step toward maintaining eye health and clarity.
