Eyes
Astigmatism
This condition usually refers to the shape of the very front surface of the eye (the cornea) where images are not focused correctly because of the different curvature of the corneas in different meridians. The analogy often used to describe astigmatism is “soccer balls are round/spherical” whereas “a rugby ball is like astigmatism” with different curvatures in the different meridians. Symptoms here can be tiredness, headaches as well as blurriness when looking at distance and/or near.
Eyes
Sight is one of our most treasured senses. Some say about 80% of our perceptions are visual. So looking after your eyes is vital and regular eye examinations play an important role in ensuring you are seeing as well as you should be and any underlying problems are detected early.
The eye is a wonderful but highly complex organ and unfortunately sometimes things can go wrong. A comprehensive eye test at Vision X has an emphasis on checking eye health and looking for early signs of glaucoma, cataracts, macular degeneration and other eye diseases; as well as problems associated with some systemic issues e.g. diabetes.
Hyperopia
Hyperopia is when images are focused behind the retina and if possible, the eye compensates for this by “focusing”. This extra muscular effort often gives eyestrain symptoms of tiredness and headaches and even blurriness if the eye cannot focus well enough.
Myopia
Myopia typically gives the symptom of distance vision blur and is caused by images being focused in the eye in front of the retina (the light sensitive back of the eye). It is thought to be related to genetics, eye growth and in more recent times the environmental factor of doing lots of near vision tasks.
Presbyopia
Presbyopia refers to the condition where the eye loses its ability to focus on close objects. It relates to the lens inside the eyes losing its flexibility and ability to focus. It is not the muscles losing their ability and consequently eye exercises cannot resolve this issue. It happens to virtually everybody and is not related to doing too many near vision tasks. Typically in a person who has previously had good eye sight, reading glasses may be required. The condition usually manifests itself in the 40’s.
