Unless you’ve been directly affected by vision problems, or know someone that has, it can be difficult to understand the devastating effects visual impairment can have. And with a staggering 285 million people across the globe are blind or visually impaired – it’s a key issue in public health that we need to speak about more often.

That’s why we’re keen to support World Sight Day on October 12th, a time where people across the globe can focus on blindness and visual impairment. At Dominic Tunnell Opticians, we think the first step to eye health is through having an eye examination.

What can an eye examination tell you?

By looking closely at your eyes, an optician can tell you more about your health than you might think.


We can tell if you are suffering from glaucoma, which can be easily treated with eye drops, laser eye surgery or surgery. This is one of the eye conditions that can cause significant visual impairment, but can be treated relatively simply.

Macular degeneration

One of the most common causes of visual impairment is macular degeneration. There are two types of age-related macular degeneration (ARMD) – dry AMD and wet AMD. Although there are no cures for them, symptoms of dry AMD can be alleviated through diet, and wet AMD can be treated with laser eye surgery or anti-VEGF medication.

Brain tumours

Although it’s rare for an optician to find something as serious as a brain tumour, it does occasionally happen. Tumours can cause swelling in the optic nerve and pressure behind the eyes, which will impact your vision. If your optician finds anything of concern, you will be referred to have it checked out further.

High blood pressure

By looking at the back of your eyes, your optician can see lots of blood vessels that can be key in detecting whether you have high blood pressure. If there are irregular-looking blood vessels in the retina with kinks or bends in, it may be that they have become distorted by high blood pressure.

High cholesterol

It is well known that having high cholesterol can lead to health problems like heart disease and stroke, but it doesn’t always have symptoms. However, an optician is sometimes able to spot little lumps of cholesterol running through blood vessels in the eye, which can result in patchy vision.

If you’re keen to take care of your sight and to keep your eyes as healthy as possible, why not book in with our specialists for a quick check up? While an eye test might not be something you prioritise, it’s clear to see how it could save your vision and even your life. You can reach our Worcester-based practice on: 01905 613020.
