What is Myopia?
Myopia is also known as nearsightedness. Myopia is defined as a refractive disorder of the eye. It has become more common in recent years. The exact cause of myopia is not yet known but studies suggest that eye fatigue due to excessive computer usage, genetic predisposition, other prolonged near vision tasks or spending longs hours in front of the television are leading causes of myopia.
What usually causes myopia?
Myopia generally occurs if the eyeball is excessively long which makes it relative to the concentrating power of the lens and the cornea of the eyes. This makes the light rays focus at a point in the front portion of the retina, rather than on the surface. Myopia usually begins during childhood. If one or both your parents have myopia, you are at a higher risk of developing myopia. It also progresses and worsens with age if proper care isn’t taken.
Treatment for myopia:
Myopia or nearsightedness can be treated by wearing contact lenses or glasses. Though this doesn’t cure myopia completely, but it prevents the power from increasing. If your degree of myopia is high, it is advisable to opt for a refractive surgery. This surgery usually eliminates the need for contacts or glasses. Excimer laser s the most common laser used for correcting vision. Contact lenses and glasses need not be worn every time of the day. It can only be worn when you want clear distance vision, like while watching a movie, looking at a chalkboard or while driving.

Do you wake up to see red shot eyes every morning? Along with this, if you are experiencing trouble, you might want to know if it is necessary to visit an ophthalmologist. Known as blurred vision and bloodshot eyes, these are two of the most common symptoms of many health conditions. From eye infection to eye injury, allergies, or any other physical condition can be the root cause behind them.
Read on further to understand how to proceed in such case:
What is redness of eyes?
The redness of eyes refers to a condition where the blood vessels, which are there right at the surface of the eyes, expand excessively and becomes congested with blood, turning the white areas of the eyes look reddish. It can be a physical condition or the presence of some irritants or infection causing the outer membrane of the eyeball to swell. Usually painless, in the majority of the cases it doesn't require medical attention.
What is blurry vision?
The term blurry vision usually refers to the loss of clarity in one’s eyesight. When someone's vision gets blurry, he or she fails to see the objects clearly, as they appear hazy and out of focus. One can have a dim or clouded vision in either any one of his eyes or in both of them. When left untreated for long, blurry vision can affect part or whole of vision.
What are the causes?
There are a number of factors that can cause redness of eyes that include allergies, inflammation affecting the eyelids, use of certain eye drops, foreign objects getting in the eye, decreased tear production or dry eyes, various corneal condition, any kind of injury to the eyes, conjunctivitis, inflammation of the eye’s middle layer, any condition damaging the optic nerve and others.
Just like the bloodshot eyes, there can be various reasons behind blurred vision as well. Some of the most common causes are cataracts, injury or trauma to the eyes, optic neuritis, corneal scarring, corneal abrasions, retinopathy, migraine headaches, significantly fluctuating blood sugar levels and more.
What are the complications of eye redness?
Most causes of eye redness will not result in serious complications. If you have an infection that causes vision changes, this may affect your ability to perform basic tasks such as cooking or driving. Vision impairments in these areas can result in accidental injury. Infections that are not treated may also result in permanent damage to the eye. For example:
If eye redness does not resolve in two days, you should call your doctor.
What is the treatment?
While it might be just the rough handling of eyes that cause these symptoms, they may also be due to a condition that needs medical attention. When the blurred vision and the redness of the eyes are indeed due to some underlying medical condition, such as a migraine, or stroke, or blood sugar, etc., first treating those conditions is important.
Apart from the medical treatment, incorporating few practices such as avoiding rubbing the eyes, ensure the environment is allergen-free, or rinsing the eyes with cool water can help in preventing the condition from deteriorating further.
Remember, while some of the health conditions causing bloodshot eyes and blurry vision can be benign, others can be severe and may need immediate medical attention. Therefore, whenever experiencing any of these two conditions, don’t hesitate in consulting with an ophthalmologist right away. In case you have a concern or query you can always consult an expert & get answers to your questions!
When was the last time you visited an ophthalmologist? Chances are that unless you faced a problem in your eyes recently, it must have been months or even years. Most people only visit an eye specialist’s clinic when they experience some eye problem. This is not a good practice since the best way to avoid severe eye complications is to detect them in their early stages. Since some eye conditions are asymptomatic in their early stages, these conditions cannot be detected without a comprehensive eye exam. Either you must be aware of warning signs or visit an ophthalmologist once a year to avoid eye problems getting severe.
Warning signs that need immediate attention
Prevention is always better than cure and eyes are one part of your body that you most likely ignore unless the problems start looming large. When the warning signs are felt, it is better to seek medical attention to rule out any sort of complication.
The most common vision problems are shortsightedness and farsightedness. Shortsightedness is when a person sees close objects clearly while distant objects appear blurry. It is more common than farsightedness and affects about 70% of the Asian population.
When there is a refractive issue, the prescription usually has a plus/minus with it and also a number. A ‘minus’ symbol is used to represent shortsightedness; the greater the number of the glasses, the higher the shortsightedness. High myopia is a more severe form of shortsightedness where the power is -6.0 or higher.
As mentioned, the person will be able to see nearby objects but will have difficulty seeing far off objects.
How it happens?
Vision can be explained by a physical process where light passes through a lens and falls on the retina in the posterior portion of the eye where it forms an image. This is then sent to the brain where it is read and interpreted as a particular object. When the lens becomes elongated, the image that is formed is distorted in that it is formed in front of the retina and not on the retina. Though it gradually settles down with adulthood, in most cases, it progresses and requires corrective lenses. The corrective lenses ensure the image falls on the retina and visual perception is improved.
Eye Strain is an umbrella term that denotes a number of symptoms that relate to the extended use of eyes as well as discomfort that may come from excessive smartphone and computer use. This condition may or may not lead to significant eye damage and is usually characterised by blurry vision, headaches and a feeling of dryness in the eye as you blink less which creates less tears. This may happen due to the extended use of the eye when you are following objects on a screen or staring at a screen for too long. So, is eye strain the cause of your headaches?

Causes: Eye Strain or Asthenopia is caused by concentrating on visually intense tasks like reading from texts that have a fine print, the use of computers and other screens for prolonged periods, and trying to focus on objects in the dark. This can lead to distress of the muscles in this area which can also cause eye strain leading to a variety of symptoms including double imagery and even headaches and mild migraine like conditions.
Eye Muscle Imbalance: When there is eye strain which leads to headaches, it can also give rise to eye muscle imbalance which makes it difficult to concentrate with both eyes at the same time. In such cases, one may need bifocal glasses so as to fix the issue and prevent such debilitating headaches to remain on a persistent basis.
Diagnosis: Digital eye fatigue and ocular eye strain leading to headaches can be diagnosed by a doctor with the help of regular eye examinations. In any case, one should have the eyes checked at least once a year. This is especially important if your job involves sitting in front of the computer screen for prolonged hours.
Symptoms: There are a variety of symptoms of these headaches that are caused by eye strain. Apart from blurry vision which does not allow the patient to see properly and clearly without glasses, it can also cause headaches with symptoms like nausea and sensitivity to light. Retinal or eye migraines do not necessarily have to come with headaches, but the pressure can be painful enough.
Treatment: To begin with, the best form of treatment for headaches born from eye strain includes prevention which can be done by getting plenty of rest and sleep even as we limit the hours spent in front of the screen. One can also lower the resolution of the screen and make it more ambient. Also, the screen should be placed at a considerable distance from the eyes. The doctor can also prescribe glasses and eye drops for better eye lubrication. If you wish to discuss about any specific problem, you can consult an Ophthalmologist.
Myopia is a common refractive error of the eye that makes it difficult to focus on far away objects. People who are nearsighted will see objects close to them clearly, while those further away appear blurry. Myopia is natural. An overall longer shape of the eye usually causes myopia, so it is a naturally occurring visual problem that cannot be prevented. Nearsightedness tends to run in families, but you don't need to have a myopic parent to develop it. Myopia begins at an early age and worsens in the teenage years, but generally stabilizes in adulthood.
Here are the most common signs and symptoms of myopia:
Causes of Myopia
Nearsightedness happens when your eye is longer than normal, or, less often, when your cornea is too curved. It’s a problem in the focusing mechanism of the eyes. However, the exact cause of myopia is not known. Research about myopia supports two key risk factors:
Treatment Options for Myopia (Nearsightedness)
When treating myopia, the goal is to help your eyes focus on far away objects. The most common way to achieve this is through
Adults who have developed cataracts may also have their myopia corrected with an intraocular lens (IOL) that replaces the human lens during cataract surgery. The most appropriate treatment depends on your eyes and your lifestyle. Nearsightedness can also be corrected as part of the cataract surgery procedure.
