By Willie T. Ong, MDAs we age, our senses get a little weaker, and our eyes undergo some changes. The eye lens becomes cloudy and loses its flexibility. The back of the eyes (retina) can become less sensitive to light, and a condition called glaucoma becomes more common.
How do we preserve our eyesight as we age? A lot of the things I know about the eyes I learned from well-known ophthalmologist Dr. Manuel Agulto. He’s the eye doctor of former First Lady Imelda Marcos. Here are some basic do’s and don’ts concerning eye care:
Don’t’s
• Avoid the glare. Don’t stare at the sun and other bright objects. “This is my number one tip to protect your eyes,” says Dr. Agulto. Looking directly at bright lights and laser pointers can be harmful to your eyes. Try to dim TV screens and computer monitors a bit, too.
• Don’t work in poor light. Reading in poor light can strain your eyes. Use a soft white light that doesn’t produce glare and reflect directly on your eyes.
• Avoid long hours at the computer or TV. Try the 20-20-20 rule: Every 20 minutes, look away about 20 feet in front of you for 20 seconds. This can help reduce eyestrain, especially if you work in front of the computer a lot. Blinking is also beneficial as it lubricates the eyes. Sometimes being too engrossed in your work makes you forget to blink and rest your eyes.
• Stop smoking and avoid second-hand smoke. Smoking is as bad for your eyes as it is for your health. Studies have linked smoking to an increased risk of developing age-related macular degeneration, cataract, and optic nerve damage. These conditions can lead to blindness.
• Avoid dusty areas. Haven’t you noticed your eyes turning red after being exposed to dust? This usually happens when riding jeepneys and buses without air-conditioning. Dust gets into your eyes and may cause harm.
Do’s
• Eat eye-friendly foods. You’ve probably heard that carrots and vitamin A are good for your eyes. But eating a diet rich in fruits and vegetables, particularly dark leafy greens such as kangkong, broccoli, camote tops (talbos), and spinach, is important. The yellow variety of watermelon contains lutein, which is good for the eyes. Research has also shown that eating fish high in omega-3 fatty acids is helpful, too.
• Wear sunglasses. Sunglasses can make you look cool, but their most important job is to protect your eyes from the sun’s ultraviolet rays. When purchasing sunglasses, look for the types that block out 99 to 100 percent of both UV-A and UV-B radiation. Make sure your glasses are scratch-free.
• Exercise. Did you know that 30 minutes of exercise can reduce your eye pressure by 20 percent? Deep slow breathing can also reduce eye pressure by increasing the drainage of eye fluid (called the lymphatic system). Thus, both exercise and deep breathing may help patients with glaucoma, a condition where one experiences a headache and an increase in eye pressure.
• Wear protective eyewear. There is a reason why some athletes wear protective eyewear. Even for active kids, protective eyewear may save one’s eyesight. Protective eyewear refers to safety glasses and goggles, safety shields, and eye guards especially designed for a certain activity (like basketball or swimming). Most protective eyewear lenses are made of polycarbonate, which is 10 times stronger than plastic. Visit your eye care centers and sporting goods stores.
• Wash your hands. To avoid troublesome eye infections like sore eyes and sty, wash your hands several times a day. Don’t go rubbing your fingers on your eyes after shaking hands with someone. That’s a sure way to get sore eyes. If you wear contact lenses, make sure your hands are clean before putting them in or taking them out. Follow disinfection procedures with your contact lenses.
• Rest your eyes. If you’re talking over the phone and you don’t really need to use your eyes, just close it while talking to your friend. Your eyes will feel rested and fresh.
• Sleep eight hours. Getting enough sleep will help your eyes recover from a long day’s work. Seven to eight hours of sleep is great. Make sure to wash your eyes with clean water every night and every morning when you wake up. This will help keep them from getting infected.
• Check your blood sugar. Diabetics are at higher risk for eye disease. That is why they need a comprehensive eye exam at least once a year. If you have diabetic retinopathy, you may need an eye exam more often. A major study shows that better control of blood sugar levels slows down diabetic eye disease (called proliferative retinopathy). Better sugar control also reduces the need for laser surgery. If you’re diabetic, see your eye specialist yearly.
• To help improve vision, consider the Bates Method of eye exercises. To rest your eyes, cup them with your hands for a few minutes. Do the Bates eye exercise: Hold one finger around eight inches in front of you and another finger at arm’s length. Then focus your eyes alternately on the near finger and then the far finger. Do this for 20 times to exercise the eye muscles.
• Get a yearly eye checkup. Many common eye diseases (glaucoma, diabetic eye disease, and age-related macular degeneration) often have no warning signs. You might think that your vision is fine, but visiting your ophthalmologist is the only way to make sure. You may also visit your optometrist for your reading glasses needs. Remember, your eyes get tired and sick, too. Don’t take them for granted.

How are floaters treated?
ReplyDeleteFor people who have floaters that are simply annoying, no treatment is recommended.
On rare occasions, floaters can be so dense and numerous that they significantly affect vision. In these cases, a vitrectomy, a surgical procedure that removes floaters from the vitreous, may be needed.
A vitrectomy removes the vitreous gel, along with its floating debris, from the eye. The vitreous is replaced with a salt solution. Because the vitreous is mostly water, you will not notice any change between the salt solution and the original vitreous.
This operation carries significant risks to sight because of possible complications, which include retinal detachment, retinal tears, and cataract. Most eye surgeons are reluctant to recommend this surgery unless the floaters seriously interfere with vision.
What are floaters?
ReplyDeleteFloaters are little "cobwebs" or specks that float about in your field of vision. They are small, dark, shadowy shapes that can look like spots, thread-like strands, or squiggly lines. They move as your eyes move and seem to dart away when you try to look at them directly. They do not follow your eye movements precisely, and usually drift when your eyes stop moving.
Most people have floaters and learn to ignore them; they are usually not noticed until they become numerous or more prominent. Floaters can become apparent when looking at something bright, such as white paper or a blue sky.

Frequently Asked Questions about Floaters
Floaters and Retinal Detachment
Sometimes a section of the vitreous pulls the fine fibers away from the retina all at once, rather than gradually, causing many new floaters to appear suddenly. This is called a vitreous detachment, which in most cases is not sight-threatening and requires no treatment.
However, a sudden increase in floaters, possibly accompanied by light flashes or peripheral (side) vision loss, could indicate a retinal detachment. A retinal detachment occurs when any part of the retina, the eye's light-sensitive tissue, is lifted or pulled from its normal position at the back wall of the eye.
A retinal detachment is a serious condition and should always be considered an emergency. If left untreated, it can lead to permanent visual impairment within two or three days or even blindness in the eye.
Those who experience a sudden increase in floaters, flashes of light in peripheral vision, or a loss of peripheral vision should have an eye care professional examine their eyes as soon as possible.
