- What is short-sightedness (myopia)?
Short-sightedness (myopia) is when you have trouble seeing in the distance. Your vision is clear when you look at things up close, but further away objects become out of focus or fuzzy. How short-sighted you are and how far away things start to get blurred is measured when you have an eye test. The test results will determine your prescription.
- What is long-sightedness (hyperopia)?
Long-sightedness (hyperopia) is when you can see objects clearly at a distance, but find it hard to focus on something that is close to you. In more severe cases, it can be difficult to focus on objects at any distance.
- What is astigmatism?
Astigmatism is a very common eye condition that can affect people of any age. It is due to the eye not being completely round, often shaped more like a rugby ball. Your vision will be blurred at any distance if you have astigmatism. The degree of distortion will vary, depending on the level of astigmatism.
- What is presbyopia?
Presbyopia is an age-related condition that affects almost everyone. As you get older and into middle-age, you may find it harder to focus on nearby objects like book or magazine print, especially in low light. Without vision correction, presbyopia can lead to headaches and eye fatigue.
- What are cataracts?
Cataracts are when the lens inside your eye becomes cloudy. This can make your vision hazy and can increase glare. Cataracts usually develop with age but can also be caused by a genetic predisposition. They are the most common cause of blindness. However, cataracts can almost always be successfully treated with surgery.
- What is glaucoma?
Glaucoma is a condition of increased pressure within the eyeball, which causes gradual loss of sight that can lead to blindness. It is important to have regular eye tests, especially as you get older, because glaucoma can be difficult to detect. You may be more at risk if there is a family history of glaucoma.
Glaucoma can be easily treated with eye drops if it is detected in good time. In more severe cases, treatment can involve laser vision correction or surgery.
- What is macular degeneration?
Age-related macular degeneration (AMD) is an eye condition that typically develops in people over 65. However, some people experience its onset in their 40s and 50s. It affects your central field of vision, making it distorted and blurry. AMD does not necessarily lead to total loss of sight, because quite often your peripheral (side) vision remains intact.
