Dry Eye or Red Eye Assessments

Dry eye, red eye or generally irritable feeling eyes are a very common complaint. Symptoms include gritty or sandy feeling, hot burning feeling or tired heavy lids. Sometime there is discharge on the lashes. The reasons for dry or red eye can be numerous and we can easily investigate any signs or symptoms using our high magnification setting on an instrument called a slit-lamp biomicroscope.

Often the cause of dry eye is environmental, resulting from air-conditioning or central heating. Reduced blink rates or incomplete blinking are well documented in screen users and this can destabilise the tear film, causing dry eye symptoms.

Other reasons for dry eye include poor meibomian gland function. These glands produce the oily part of our tears and if not functioning well can lead to evaporative dry eye.

Reduced tear volume can be due to issues with the lacrimal gland, and sometimes there can be problems with the mucin layer of the tears.

Red eyes often occur from irritation, infection, inflammation or haemorrhages and using the slit-lamp, the cause of the irritation can be determined

Other common issues are allergies, which can cause papillae (small bumps) on the backs of the eyelids and these often create a gritty sensation and are often itchy.

Appropriate advice and eye drops, gels, ointments, washes and masks are available to purchase in practice on the recommendation from the optometrist. These products can also be purchased on our Online Shop.

Glaucoma Screening

Glaucoma is common eye disease that can lead to blindness if undetected. There are several different forms of the disease but the most common form of this disease is symptom-less. It is routinely checked for in patients over the age of 35 and in patients who have family members with the disease. A screening facility is also available where the eye pressures, optic nerve heads, and visual fields are checked for signs of the disease.

Dyslexia-Migraine-Epilepsy-Light Sensitivity-Visual Stress
(Meares-Irlen Scotopic Sensitivity Syndrome)

Visual stress, which affects 5% of the population, is a condition that often leads to reading difficulties. Visual stress can arise from light sensitivity disorders such as migraine and epilepsy, but is also a problem for people with dyslexia. Scientific research shows that visual stress from reading can be reduced by using special coloured filters that are specific to each individual. Coloured overlays are often used in the initial stages of assessment, and if found to be helpful then precision tints are prescribed for spectacles or contact lenses using our specialised instrument called the Intuitive Colorimeter. These tints can permit a more fluent, efficient and comfortable reading and are commonly prescribed to help those with dyslexia

Colour Vision Assessment

Colour vision is assessed using a variety of colour vision testing equipment. The Ishihara plates, the City University test, and the Farnsworth-Munsell 100 Hue test are the main tests used. For children we use the HRR plates or the CVTME, which use easily recognised symbols and pictures which can be named by the child.

Driving Licence Eyesight Report Form for Group 2 Drivers
(truck, bus etc)

Vision standards for Group 2 require a full binocular visual field assessment and using our Henson 8000 visual field analyser we can carry out this important aspect of the assessment. Our optometrists can complete the RSA NDLS Driving Licence Eyesight Report Form.
