Understanding your prescription

We provide advice specific to your needs

We take great care to make sure all our customers are happy with their prescriptions. This includes helping you to understand what type of prescription you have and what the more technical terms actually mean.

Clinical terminology


Myopia, or short-sightedness, happens when light is focused in front of the retina rather than directly on the retina as it should be. This causes the things you see in the distance to be blurred.

Glasses may be needed all the time, or just for specific tasks such as driving or watching television. Short-sightedness often develops when you are young.


Hypermetropia, or long-sightedness, happens when light is focused behind the retina rather than on the retina as it should be. To compensate for this, your eyes have to make a big effort to refocus which can cause headaches, sore eyes and blurry vision. Glasses may be needed all the time, or just for near vision tasks such as reading and using your smartphone or computer.



Astigmatism is the name for when the curvature of the cornea or the lens inside the eye is not perfectly round. It can sometimes cause blurred vision or headaches. With this condition, glasses may be needed all the time, or just for specific tasks.


Presbyopia happens when the lens becomes less flexible and can’t focus on objects close by. This occurs naturally with age and gradually makes things like reading more difficult. For example, as you hit your 40s you may notice that you need to hold a book further away to focus or that you need more light for small print. There are a few different ways to correct the vision of someone with presbyopia including varifocals, reading glasses and even contact lenses.
