Age related Macula Degeneration
Also known as Macula Degeneration
The macula is the part of the retina which is used for fine visual tasks. In macula degeneration, this area is damaged by the buildup of deposits and sometimes leakage from blood vessels.
Amblyopia or lazy eye is the most common cause of poor sight in children. This occurs when the part of the brain the deals with the vision in that eye fails to develop normally, particularly in the first eight years of life. This decreased development is generally caused by the reduced quality of vision in the affected eye.
Astigmatism is an eye condition resulting from an irregular curvature of the eye.
The eye is often more curved in one plane than the other, like a rugby ball compared with a soccer ball. Light is focused differently, giving not one, but two image points on the retina (the back area of the eye that processes visual images).
A cataract is a cloudiness of the lens in the eye, which lies behind the iris and the pupil. The lens works much like a camera lens, focusing light onto the retina at the back of the eye. The lens also adjusts the eye’s focus, letting us see things clearly both up close and far away.
Colour Vision Defects
In the eye are many small light sensing cells called photoreceptors. There are 3 different types of photoreceptors involved in sensing colour, each one reacts more strongly to one wavelength of light than other wavelengths.
However, as you know, there are more than three different colours around, so how does that work?
Flashes and Floaters
Inside the eye is a clear gel overlying the nerve layer, the retina, which assists in maintaining normal vision and eye health. Over time parts of the gel become more liquid and can have small opacities, these can create the appearance of floaters in vision. In most cases these are not a cause for concern and are a normal ageing change.
Here are a few tips on how to properly care for your glasses to ensure you continue to get clear, comfortable vision through them.
Always remove and put on your glasses with both hands to reduce stress on the frame.
Glaucoma is a slow progressive disease of the optic nerve. The optic nerve is important as it carries all the information about what you see to your brain. Glaucoma is often called the “sneak thief of sight” as you do not notice symptoms until the condition is very advanced.
Hyperopia, also known as long-sightedness. Generally, a hyperopic, or long sighted eye is smaller than normal. Because it is smaller than normal when the eye is fully relaxed light from objects you are looking at is not focused on the retina, but is focused behind the retina, giving blurred vision.
Myopia is a condition where a distant object is focused in front of the retina resulting in blurred distance vision. Myopic eyes tend to see better up close than in the distance.
Presbyopia is when the eye begins to loose the ability to change focus from distance to near. It is not an eye disease, but a normal age related process.
A pterygium is a raised growth that forms on the front surface of the eye. A very early pterygium is an area of redness and thickening of the conjunctiva, the thin clear layer of skin over the front of the white part of the eye.
Strabismus or is also known as a squint. This is when the two eyes do not point in the same direction when looking at objects. It can be caused by large hyperopic prescriptions, or by the eye muscles not coordinating well together.
A subconjunctival haemorrhage is caused by a bleed of a small blood vessel on the white of the eye. The blood accumulates between the tissues on the white of the eye causing the eye to look very red.
