The Causes Of Poor Eyesight Essay Topics

Watching TV can reveal many eyesight problems - here are a few that could affect you while you are sitting in front of your favourite program.

How do refractive errors cause blurred vision?

If you find it hard to focus on the TV, it could be the result of a refractive error preventing you from seeing clearly. If you are having trouble with your close up vision you may have long-sightedness. This will make it harder to focus when looking at a computer. Objects may become blurry and hard to see. As people get older they often develop an age-related form of this known as presbyopia.

On the other hand, if you are struggling to see items in the distance, you may suffer from short-sightedness. This will be obvious if you are trying to watch TV from a distance. Short-sightedness, or myopia, usually reveals itself in childhood or adolescence. Blurry vision could also be the result of astigmatism, which can cause trouble at any distance as it means objects cannot be focussed properly on your retina - the light sensitive layer at the back of the eye. All of these issues can be corrected using glasses, contact lenses or by surgery. However, you will need to have an eye test at the optometrist to determine whether this is the cause of your blurry vision.

Why do I have double vision when looking at the computer?

Double vision, or diplopia, can be caused by a variety of issues. However, if it only affects you when you are watching TV or watching your favourite shows on a computer, it may be the result of eye strain. This is when your eyes work really hard on one task. It simply means that your eyes have become tired. While no damage will result, it is important to take regular breaks and make sure you are blinking often. Eye strain can also cause sore eyes and headaches. If regular breaks do not relieve your symptoms, you should make an appointment with your optometrist for a check up to ensure there is nothing else going on. Some people find that eye strain is worse at night time. This could be because you are more tired, or it could be a combination of eye fatigue and a refractive error. Corrective lenses should help to relieve this problem.

Why do the colours on TV look different between eyes with macular degeneration?

Macular degeneration often leads to colour vision changes and this is normal with the progression of the disease. Macular degeneration occurs when the macula, or part of the retina responsible for sharp, central vision, begins to decline. This is essential for tasks such as reading and writing. As a result of the disease, central vision loss may occur. It can be diagnosed as a dry or wet degeneration. Wet means there is growth of new blood vessels in an area where they are not meant to be. There is no cure for dry macular degeneration but it can change to become wet in time. There are some forms of treatment available for wet degeneration. Consult your optometrist to find out what could be suitable for you. You may want to visit your optometrist if you are concerned about your retinas and he or she can refer you to an eye specialist if required.

Why does my child tilt his or her head when watching TV?

If you have a young child, they may tilt their head to correct a vertical imbalance between their two eyes to avoid double vision. However, if there is no muscle imbalance and the head tilting only occurs in front of the TV, it could just be an odd habit. Make an appointment with your optometrist if you are unsure about this.  

It is estimated that up to 60% of the UK’s population require glasses or contact lenses, including 2 million teenagers.

The high number of people with bad eyesight can be attributed to a number of factors, including an ever-ageing population; getting older is a primary cause of poor vision.

While many people suffer the daily routine (and inconvenience) of washing contact lenses and breaking or losing spectacles, how many of us actually know what causes bad eyesight?

If you’re in the dark about the causes of poor eyesight, Freedom Vision is here to shed some light on the matter. Read on to discover a few of the major causes of bad eyesight in the UK…

Eye Strain

Perhaps the most common cause of bad eyesight is general eye strain. In a world where are constantly reading -be it books, our smartphones or computer screens- our eyes become easily tired by intense and prolonged concentration.

Focusing on a computer screen for too long can also cause eye strain, making it harder for eyes to focus on objects that are further away. While it’s not true that your eyes will “go square” (as so many of us were told as children), it is true that staring at television and computer screens is not good for the eyes.

The stereotypical, heavy-rimmed spectacle look of scholars and scientists can also be directly attributed to the nature of their work, with many hours spent reading, writing and concentrating.

So, in a world where it’s almost impossible to avoid reading, how can we dodge the dreaded eye strain?  If you work in a job which requires you to use the computer all day, try to give your eyes a regular break from the screen. Try and look at an object 20 feet away, for 20 seconds, every 20 minutes. ree casino play is truly entertaining. To come out logically from this issue, you must be aware of about a few games that are well-liked in casino. You can select from a number of totally free book of ra online ohne anmeldung , a few of which require strategy while some are just based on luck. There are several different varieties of internet casino games to select from, every one of them with their own characteristics and exciting elements of luck and at times skill and strategy. You can also adjust your screen settings to minimize brightness and glare. When circumstances allow -during studying, for example- it’s a great idea to go for a walk once in a while, changing your surrounding and allowing your eyes to focus on something different.


Glaucoma is a serious medial condition caused by increased pressure within the eye itself. This pressure eventually leads to vision becoming impaired.

There are two types of Glaucoma; Open-Angle and Closed-Angle. Open-Angle Glaucoma is a more prolonged but painless condition, while Closed-Angle Glaucoma can be more sudden in onset and causes acute pain in the eye.

Glaucoma can be very difficult to treat and in some cases has led to blindness, but only 3% of people over the age of 50 will ever contract the condition.


As previously mentioned, natural ageing is the primary cause of deteriorating eyesight in the UK.

Although any part of the eye and vision can deteriorate over time, the most common cause of vision loss later in life is the lens of the eyeball becoming thicker and more rigid. Laser eye surgery and refractive lens exchange can correct visual problems in younger and middle-aged people respectively, but few of us will reach old age and still retain 20/20 vision, with or without surgery.


Cataracts is perhaps the most noticeable of all major eye issues. The condition causes a cloud or opaqueness to cover the eye, causing loss of vision as well as a glare intolerance.

The most common causes of cataracts is the normal ageing process, although a sudden trauma and certain diseases cant trigger the clouding process.

Luckily, cataracts can be treated in a couple of ways. You can find out more about cataracts and its treatment here.


Diabetes is another major cause of visual problems in the UK. Patients with diabetes often suffer from sight issues, as diabetes causes damage to the retina in the back of the eye.

Fortunately, most diabetics will never suffer from Diabetic Eye Disease (also known as DED), and it is usually only people who manage their condition poorly who are at risk of developing the condition.

For those that do develop DED, the loss of vision can be sudden, after a period of gradual decline. The best defence for diabetics against visual problems is to manage their condition properly, with the help of health care providers, and have their eyesight checked on a regular basis.

There are many more reasons your eyesight may be getting worse…

There are a plethora of other reasons why your eyesight may be in decline, such as the growth of scar tissue called Pterygium or Age-related Macular Degeneration, a condition in which the cells of the macular in the eye degenerate due to abnormal blood vessels growing in the retina. AMD is usually caused by the natural ageing process, and is the leading cause of blindness in Australia. While AMD is untreatable, most eye conditions can be solved with surgery or another form of treatment.
