Cataract can be defined as the clouding of the natural lenses in the eyes. This is caused by the clumping of protein in the eye lens. Cataract is a common eye disorder and the leading cause of loss of vision in people who are past their fortieth birthday. Cataract can occur in one or both eyes. When diagnosed properly, cataract can be treated with surgery to prevent blindness.
Depending on where and how they develop, there are many types of cataract. The most common amongst these are:
- Subcapsular cataract: These occur at the back of the eye lens. Diabetic patients are very susceptible to this kind of cataract.
- Nuclear cataract: Yellowish-brown cataract that form in the center of the lens are called nuclear cataract. This is usually seen in cataract caused by ageing.
- Cortical cataract: Cataract in the lens cortex are known as cortical cataract. These are wedge shaped and whitish in color. Spokes protruding out of these opaque wedges can be seen moving towards the center of the eye.
- Congenital cataract: Though they are not common, babies can also have cataract. Cataract formed at birth or within the first year of a baby's birth are known as congenital cataract.
- Secondary cataract: Cataract is one of the known side effects of diabetes and glaucoma. Some steroids and medicines are also linked to cataract.
- Traumatic cataract: If your vision becomes cloudy years after an eye injury, it could be a traumatic cataract. It can take several years for this to happen.
- Radiation cataract: Exposure to radiation can also lead to cataract. This is seen sometimes in patients who have undergone radiation therapy to fight diseases like cancer.
Though the type of cataract might differ from person to person, the symptoms are usually the same. Some of the common symptoms of cataract are:
- Blurred vision
- Reduced night vision
- Increased sensitivity to light and glare
- Seeing halos around lights
- Colors appearing faded
- Double vision
A reading test is the first step towards diagnosing cataracts. This is followed by tests to measure the eye pressure. Your doctor will also need to dilate the pupil to check the condition of the optic nerves and retina.
Surgery is the safest way to remove a cataract. Surgery is usually recommended when cataract begin inhibiting your daily life such as preventing you from driving, interfering with reading etc.
In most cases, this can be done as an outpatient procedure. The earlier it is diagnosed, the easier it is to treat. Hence, if you notice any of the symptoms mentioned above, get your eyes checked at once. The surgery is a day-care surgery only, so a person can go home the same day.
5 myths about eye health and the real facts behind them
Your eyes are an important part of your health. There are many things you can do to keep them healthy and make sure you are seeing your best. However, there are a number of myths regarding what you should do and what you shouldn't do when it comes to maintaining good eye health.
Here are 5 of those myths busted:
Myth #1: reading in dim light and sitting too close to the tv hurts your eyes
Fact: sitting too close to the tv, you may feel eye strain or get a headache from reading in the dark, but it will not weaken your eyes. It fatigues your eyes but does not harm your eye health in any way.
Myth #2: eating carrots will improve your vision
Fact: carrots are rich in vitamin a, a nutrient essential for good vision. But eating carrots will only provide a small amount of vitamin a. To get the optimum amount, you need to include other sources of vitamin a in your diet as well, some of which are milk, cheese, egg yolk and liver. Spinach is best for eye health. It has lutein and zeaxanthin, both of which can help prevent cataracts.
Myth #3: if you wear glasses or contacts for a continuous period, your eyes will weaken
Fact: your eyes will not grow weaker by using corrective lenses. The prescription may change over time due to aging or absence of disease but it has nothing to do with your current prescription. Some children have correctable eye problems that do require glasses to improve the condition.
Myth #4: when you get something in your eye, rub it out
Fact: this is not true for everything that gets in your eyes. If any particle falls in your eyes dust it off. But if it is sand and small debris that gets in your eye, don't touch it. Use an eye wash for flushing it out. If an object gets stuck in your eye, don't remove it or rub your eye constantly. Visit a doctor at the earliest because some serious injuries may seem minor at first.
Myth #5: dark sunglasses can protect your eyes from the sun
Fact: the color of sunglass does not ensure eye protection. Look for sunglasses that block both uva and UVB rays. Exposure to the UV-rays of sunlight can have cumulative effects on your eyes. It increases your risk for cataracts, solar retinitis, and age-related vision loss. Even if your contacts have UV protection, wear sunglasses that block 100% of uva and UVB rays for full protection.
