What are the most important signs to look out for in terms of eye damage or dental problems? Is there anything I can do to keep my eyes and teeth as healthy as possible?
Between myopia or short sightedness and hypermetropia or farsightedness, the latter is less common. However, this does not make it any less important. Farsightedness or long sightedness refers to a refractive error in the eye lens that creates problems focusing on objects nearby. This is because the light entering the eye does not converge on the retina but does so behind the retina.
Long sightedness can be caused by a number of factors. Some of these are:
Structural problems with the eye: Some people are born with structural problems. This is one of the leading causes of long sightedness. These structural conditions include:
- A cornea that is not steep enough
- A short eyeball
- A flattened lense
- A thicker than normal lense
Age: Long sightedness rarely affects children. This is a condition that becomes noticeable after the age of 40 in most cases. With age the lenses in the eyes become stiffer and do not curve normally. This is known as presbyopia.
Genetics: As with myopia, hypermetropia is also triggered by genetic faults. If someone in your family suffers from this then chances are that you will too. However, the specific genes that transfer this condition from one generation to the next have not been discovered as yet.
Underlying conditions: Long sightedness is also triggered by underlying conditions such as diabetes, under development of a baby's eye during pregnancy (read more about diabetes and pregnancy), orbital tumours and problems with the blood vessels in the retina.
Not being able to read a book clearly is one of the most common symptoms of long sightedness. Some of its other symptoms are:
- Needing to squint to focus on objects
- Pain or burning in the eyes
- Fatigue caused by reading, writing or working on a computer
- Red and watery eyes
Long sightedness can be correctly diagnosed only with a thorough eye examination. Hence it is essential to schedule one regularly. This becomes more important as a person gets older. If left untreated, it can lead to double vision which in turn can trigger two possible eye problems.
Strabismus: This is a condition where the eyes get misaligned and hence do not work in tandem. People suffering from this condition find their eyes focusing on two independent objects instead of seeing the same thing.
Amblyopia: Double vision can make one eye more dominant than the other. This makes the muscles of one eye degenerate at higher rate than the other making it lazy. This is known as amblyopia.
If you wish to discuss about any specific problem, you can consult the doctor and ask a free question.

Causes and Symptoms of Hypermetropia You Need to Know About
Hypermetropia, commonly known as long-sightedness, is a common vision condition in which distant objects appear clear, but nearby objects seem blurry or foggy. A person's ability to focus is greatly dependent on the degree of farsightedness. This condition of the eye is usually observed at birth and is also hereditary to some extent. Although, contact lenses and eye glasses are common methods of treatment, surgeries are also an option.
Before getting to understand the causes one should be aware of the structure of the eye.
The eye has two parts that focus on images
- The clear surface at the front of the eye known as the cornea
- The second part is the lens, which is a clear structure
In a normal eye, these clear surfaces have a smooth curvature. The cornea and the lens bend or refract the incoming light to direct a sharply focused image on the retina, situated at the back of your eye.
Hypermetropia is caused when
- The cornea or lens in the eye is not even or smoothly curved. In such cases, light rays are focussed behind retina which gives a blurry vision.
- The condition can also occur when the cornea of the eye is not curved enough. A shorter than the normal eye can also lead to such a condition. Convergent squint with eyes turning in is common in hypermetropes.
Due to these factors, the image is not precisely focused on the retina, causing blurry vision for nearby objects.
Some of the symptoms of farsightedness include:
- Objects that are close may appear blurry or cloudy
- Squinting the eyes might be necessary for viewing clearly
- A person may experience strain in the eye, aching and even inflammation in and around the eye
- Prolonged periods of close task like reading, writing or drawing may cause discomfort in the eye or minor headaches
Chronic eye strain and cross eyes are some of the commonly observed complications.
