Your eyes are the delicate windows to your soul; they are amazing gifts that are made up of many divisions that all play a part in focusing and inevitably enabling us to see. Can you imagine not having proper eyesight? All the pleasures that we take for granted will be affected such as admiring the scenery, driving, writing, reading, work or play.
Eyes are made up of the following parts:
- Cornea is the window of your eyes where light passes through.
- Sclera is the non-transparent white tissue, which surrounds the cornea.
- Iris is the colour part of the eye.
- Pupil is the black centre of the iris, which allows light into the eye.
- Lens is the internal focusing element, which is curved on both sides.
- Retina is a layer that is found at the back of the eye, which allows the image to be transmitted and interpreted.
- Aqueous humour is the clear liquid found between the cornea and lens.
- Vitreous humour is the clear liquid between the lens and retina.
Causes of eye problems include, but are not limited to:
