What Is Long Sight (Hyperopia)?

0 Comments

Hyperopia is an eye condition that is often better known as long sightedness.

If you have difficulty focusing on things that are close by, but find it easy to see things that are far away, there’s a chance you could be long sighted.

Long sightedness is caused when the eyeball is too short or when the lens is not round enough. This makes it difficult for the eye to focus on near objects.

What is better than 20/20?

0 Comments

We’ve been inundated with people asking us –  “What does 20/20 vision actually mean?”

So we put the question to Optical Express’ Clinical Services Director Stephen Hannan, who explains:

“By conducting research, optometrists have basically been able to gauge the standard of vision that a person should be able to see when standing 20 feet away from an eye chart. If you have 20/20 vision, it means that when you stand 20 feet away from the chart you can see exactly the same as someone with standard vision can see.”

What Is Astigmatism?

0 Comments

Astigmatism is an eye condition that can affect the clarity of your vision and make it more difficult for you to focus on objects. Astigmatism is most common in eyes where the cornea is oval like a rugby ball instead of spherical like a football.

Most astigmatic corneas have two curves; a steeper curve and a flatter curve. This causes light to focus at more than one point in the eye, resulting in blurred vision. Astigmatism can be a mild or fairly serious eye condition, with symptoms ranging from very mild blurred vision to severe blurriness resulting in squinting, fatigue and headaches.

What is Presbyopia?

0 Comments

Presbyopia is an eye condition that is characterised by an inability to focus on objects that are nearby. It is a condition that is caused by the ageing process and is common in people reaching middle age.

When reaching their 40′s and 50′s, many people find they have difficulty in focusing and suffer from presbyopia to some degree – even if they have never had any trouble with their sight in the past. This is because, as the natural lens ages, it finds it more difficult to alter its focus from distance to near.
