Specific Eye disorders

HYPERMETROPIA (Long Sight or Far Sight)

Long sighted is where the point of focus for an image is projected beyond the retina of the eye, causing a blurred image. This could be caused by the eyeball being too small or the lens not having enough focusing power.

It can be simply corrected with lenses that cause the image to focus on the retina.

MYOPIA(Short Sight or Near Sight)

Short sighted is where the point of focus for an image is projected in front of the retina of the eye, causing a blurred image. This could be caused by the eyeball being too long or the lens having too much focusing power.
It can be simply corrected with lenses that cause the image to focus on the retina.

ASTIGMATISM

This is a condition where light rays from objects are not transmitted to a single sharp focus within the eye. This is often caused by an eye that is being of an irregular shape.

CATARACT

The clear lens of the eye, which is needed to focus light and giving sharp images, becomes cloudy and hardens causing a loss of sight. Cataracts are painless and gradually develop over a long period of time. Over 50% of people aged over 65 have some form of cataract development and most cases can be treated successfully with surgery. It can be caused by age, trauma, diabetes, long term steroid therapy, excessive exposure to UV light or most likely hereditary.

GLAUCOMA

The eye needs pressure to help keep its shape. When glaucoma occurs, there is too much pressure in the eye causing damage to the optic nerve. Glaucoma unfortunately affects 2% of the UK population over the age of 40 and there are many different kinds of glaucoma.

STRABISMUS (Crossed Eyes or Wall Eyes)

This is a rare visual defect where the eyes are misaligned and point in different directions.
There are two different forms of strabismus being referred to:-

  • Cross eyes (esotropia) - Where the eye points inwards.
  • Wall eyes (exotropia) - Where the eye points outwards.
