Have you ever wondered how we are able to see in the dark or how we see such a variety of colours throughout our everyday lives? These activities are possible due to receptor cells in the retina called rods and cones which each have a specialized function. The rods are involved mainly in low-light and […]

The Eye Series: Retina
Today we are learning about the retina. The retina is a 10 layered structure located at the back of the eye. Its main function is to receive incoming light rays and convert them into electrical signals that are sent to the brain. Specialized cells in the retina called ganglion cells have tails (axons) which come […]
SMOKING AND YOUR EYES
Smoking can cause serious damage to the organs in our body including our eyes. Smoking can cause long term damaging effects to the health of our eyes and increase the likelihood of vision loss.

The Eye Series: The Ciliary Body
The ciliary body is a part of the eye and is involved in many functions of the eye. Small projections from the ciliary body, called ciliary processes, produce aqueous humor, which is a clear fluid that fills up the space between the cornea and the lens. From the ciliary body, cable-like structures called zonule fibres […]
The Eye Series: Lens
Today we will be learning about the lens in the eye. The lens is another clear structure of the eye located just behind the iris and pupil. It’s shape resembles an olive, with sides that bulge outward. The lens is a really important feature of the eye because it helps us see. It’s function is […]
The Iris and the Pupil
The iris is the coloured circle that surrounds the pupil in the center of the eye. It is mostly made up of fibres of collagen protein and muscles. Collagen fibres are arranged in a specific fashion which is different between individuals, making each person’s iris as unique as a fingerprint! Humans can have a wide […]
Cornea Anatomy and Associated Diseases
Vision is the most important sense when it comes to living everyday life. We use our sense of sight for so many important tasks such as driving, working, and playing. The eye is a visual organ with various components that all work together to provide us with sight. The cornea is a clear, dome shaped […]
The Aging Eye….and Cataracts!
What is a Cataract? Our eyes have a natural lens behind the iris (coloured part of the eye) and the pupil that helps focus light/images on the retina. Over time the lens clouds over and can slowly blur up the vision. What causes a Cataract? Cataract is a natural part of aging but cataracts can […]
