Here are a series of videos we hope may help you…
Macular degeneration (MD) covers a number of conditions which affect the macula. The conditions affect your ability to do certain tasks such as reading and watching television, but do not affect your ability to walk around as your side vision is not affected.
This video shows how age-related macular degeneration might affect vision. Macular degeneration is the leading cause of sight loss in the UK, with 1 in 10 people over the age of 65 showing some signs of this condition.
Cataracts are formed when the clear lens inside your eye becomes cloudy or misty. This is a gradual process that usually happens as we get older. It does not hurt. The early stages of a cataract do not necessarily affect your sight.
Cataracts are formed when the clear lens inside your eye becomes cloudy or misty. Cataracts may mean that you have to change your prescription for your glasses, and you may notice that your vision is less clear and distinct. Car headlights and street lights may become dazzling, and you may experience difficulty moving from shade to sunlit areas.
Floaters are more common than flashes, and look like small, dark spots or strands that float in front of your eyes. Floaters are very common and normally harmless. They are more common if you are short-sighted or as you get older. Some people notice they see flashes of light. These can be due to the movement of the gel inside the eye. Very occasionally, flashes or an increase in floaters can be a sign of retinal detachment, which needs treating as soon as possible. This is more common as you get older, or in people who are short-sighted or have had eye surgery.
Floaters are small spots or strands which cast a shadow on your retina. These can be semi-transparent or dark, and appear to float in front of your vision. If you move your eye to look directly at the floater, it will move in the same direction.
Glaucoma is a group of eye diseases where the optic nerve – which connects your eye to your brain – becomes damaged. It usually occurs when the pressure inside the eye increases.
Glaucoma is a group of eye diseases in which the optic nerve, which connects your eye to your brain, is damaged by the pressure of the fluid inside your eye.
About 2%-3% of all children have a lazy eye, clinically known as amblyopia. This may be because they have one eye that is much more short- or long-sighted than the other, or they may have a squint (where the eyes are not looking in the same direction).
If your eye is shaped more like a rugby ball than a football, light rays are focused on more than one place in the eye, so you don’t have one clear image. This may make it hard to tell ‘N’ from ‘H’, for instance.
Dry eye is a chronic (long-term) condition. This means that once you have had it, it can come back even after it has cleared up. It often affects both eyes, but one eye may be worse that the other.
Some people have eyes that are too short, which means the light focuses behind the retina at the back of the eye (they are long-sighted). This means that they have to focus more than they would if they have perfect sight, particularly on things that are close up.
When you are looking at something that is far away, your eye – if you are perfect sighted – is shaped so that the object is clearly focused on your retina. This means that the image is clear.
Some people have eyes that are too long, so the light focuses in front of the retina (they are short-sighted). This means that they cannot see things clearly if they are far away from them (such as the TV or board at school).
An eye examination is carried out by an optometrist and usually takes about 20-30 minutes. Sometimes it can take longer if you need extra tests, but this is to make sure you can see as well as possible.
