Common Eye Conditions and Problems

eye strain

When looking after your eye health, knowledge is power. It’s important to be aware of the most common eye diseases so that you can detect symptoms early and prevent harm. So, let’s break down the eight most common eye conditions.


This condition is most commonly found in the elderly, although it can develop at any age. Damage to the optic nerve is caused by an accumulation of fluid in the eye, which can eventually lead to impaired vision and even blindness. Glaucoma doesn’t usually cause any symptoms, and is often diagnosed during eye tests. So make sure you’re getting your eyes tested as often as recommended


This condition can affect babies and young children, but it’s more commonly found in adults and the elderly. The condition occurs when small, misty patches develop on the lens of the eye, causing blurry or frosted vision. It often occurs in both eyes and doesn’t tend to be painful, but can lead to a complete loss of vision over time. If you have symptoms, get checked out by your optician straight away.

3.Age-related macular degeneration

Macular degeneration has two types: ‘dry’ and ‘wet’. It’s a condition caused by damage to the retina and is most commonly found in older people, especially those who smoke. If left untreated, it can cause a loss of vision. Symptoms that warrant a visit to the optician include: blurred vision, sensitivity to bright lights, and difficulty distinguishing between colours.

4.Dry-eye syndrome

This condition is, just like the name says, characterised by having dry or irritated eyes. It occurs when the eye doesn’t produce enough tears, a problem associated with old age, wearing contact lenses, and vitamin A deficiency. Symptoms include: itchy eyes, burning sensation in eyes, blurred vision. Your optician will be able to help you with treatment.

5.Ocular Hypertension

This condition is caused by trauma to the eye and excessive production of aqueous humour. It occurs when extra pressure builds up within the eye. It doesn’t cause any obvious symptoms, thus its usually noticed by eye specialists during routine examinations. If left untreated, it can damage the optic nerve and cause complete loss of vision.


This condition occurs when the blood vessels in the eye become damaged. Retinopathy is associated with diabetes and high blood pressure, and is one of the main causes of blindness. Early detection is key to resolving the disease. The methods of treating retinopathy differ – retinopathy varies slightly to form specific types amongst patients. The most common form of treatment is laser eye therapy.

7.Lazy Eyes

Also known as Amblyopia, this occurs when an eye does not develop to the normal level. Generally, vision is weaker in the specific eye with the condition, and sometimes moves in a ‘lazy’ manner. It can occur in people of all ages, even toddlers, and usually affects only one eye. A Lazy Eye can be corrected with lenses or glasses if detected at an early stage.

8.Allergic Conjunctivitis

This is a problem that arises in eyes that suffer from allergies to things in the surrounding environment. This can range from mould, pollen, or other airborne contaminants. Common symptoms include puffy eyelids, especially right after sleeping, a burning sensation in your eye, and red eyes. It can be treated with eye drops and by staying away from what triggers the allergy.
