Eye myths busted!

I have 20/20 vision, so I couldn't have glaucoma.
Individuals with perfect vision could still have or develop glaucoma since the disease usually affects peripheral vision first and central vision last.So most people in early stages have perfect central vision. Affection of peripheral vision can be detected only by specialised tests. You can't have high eye pressure if you don't have high blood pressure.

Blood pressure and eye pressure are independent of one another.
Controlling blood pressure does not mean IOP is controlled. While high blood pressure can be associated with elevated IOP, low blood pressure is strongly associated with some types of glaucoma, for example, normal-tension glaucoma.

You can test you own peripheral vision to see if you have glaucoma.
Many people think that they can test their peripheral vision by closing one eye and trying to look at side objects. But it is impossible to evaluate the state of your vision without a true visual field test conducted in your eye doctor's office.

Glaucoma is always inherited, and your parents always have it if you have glaucoma.
Some forms of glaucoma are inherited, and researchers are actively investigating the genes responsible. But absence of glaucoma in one's family doesn't mean a person is risk-free as in many cases glaucoma is not inherited.

Eye drops can prevent or dissolve cataracts.
The Food and Drug Administration has not approved any drops that cure or delay cataracts. Some such products claim they can prevent cataracts, but cataract formation is a natural part of the eye's aging process. Other products claim they can "dissolve" cataracts. But since cataracts are not a "substance," there is nothing for the eye drops to dissolve.


Close-up tasks like reading or sewing make cataracts worse.
Cataracts are not caused by how people use their eyes. However, cataracts likely become more noticeable during close work. One sign of a cataract is the need for more light to do the same activities well.

Cataracts are reversible.
No. The lens naturally clouds as it ages. This process is unavoidable. However, its progress can be slowed by quitting smoking, eating a balanced diet and wearing sunglasses with 100% UVA and UVB protection.

Cataract surgery is dangerous, and recovery takes months.
No. Cataract surgery is one of the safest and most highly perfected surgical procedures in medicine, with more than 95 per cent success rate. Of course, as with any surgery, risks do exist and should be discussed with an eye doctor before the procedure. Patients will need to avoid bending or lifting anything heavy for up to a week after the procedure, as well as refrain from rubbing or pressing the eye. Normal activities may be resumed the day after surgery, when the eye patch is removed. Cataract patients often notice vision improvement immediately following surgery, and others will notice more gradual improvement for a few months afterwards.

Cataracts "grow back."
No cataracts cannot grow back. Cataracts develop as the lens's cells die and accumulate; they are not a "growth" that sits on top of the eye. Occasionally patients do develop a different, secondary cataract, though. When the membrane that holds the new lens implant becomes cloudy, vision can be compromised. But this can easily be treated with a laser, a painless, 15-second procedure usually done as an outpatient procedure by your eye doctor.


Reading in poor light or reading too much fine print will eventually harm your vision.
It's like saying if you take a picture in poor light, then the camera is going to be damaged. The camera analogy may also explain why vision becomes worse in the dark.In low light the pupil is enlarged, so whatever defects there are in the lens, are not corrected. When it's bright, you have a much greater depth of focus. So, more outside light can certainly help you see well.
Similarly, having to focus on a smaller area is likely to cause strain on the eyes, but not lasting damage.

Sitting too close to the TV or staring at a computer screen is bad for your eyes.
Sitting too close to a TV or staring at a computer screen for too long will hurt your eyes -- but only temporarily.Much of the problem can come from the screen, because people staring at them for long periods of time tend not to blink. If a tear film is a little on the dry side from not blinking sufficiently, then the quality of vision suffers,it’ssort of a temporary phenomenon. Some of the strain can be avoided. If you are looking at something up close, it's a good idea to take breaks and look into the distance.Children may sit close to the screen because they can. They have more of a range of accommodation and can sustain it for long periods of time. Of course, it may also signal a problem. If a kid is doing that, it may be that they need a pair of glasses.

As you get older, there's nothing you can do about your worsening vision.
Some age problems are inevitable.Cataracts are not a disease; it’s a normal aging change, not unlike grey hair. If everyone lived long enough, they would get cataracts. But at the same time, cataracts, like many vision problems, can be fixed.Cataracts, a clouding of the lens caused by the folding of proteins, can be removed to fix the problem.Many of the eye ailments that affect people when they age can be eased by following general health advice. A balanced diet can play a role in preventing some problems, as can giving up smoking, controlling cholesterol and sugar levels could help as well.


Eating carrots will improve your vision.
Diet is important to good vision, but that doesn't mean that eating carrots all day will give you eagle eyes. Vitamin A deficiency may lead to poor vision, but having an excess of the vitamin does not help eyes, however. Dark green vegetables, such as spinach and broccoli, for example, contain lutein, which is found as a yellow spot in the retina, called the macula.

It's O.K. to skip my child's first eye exam as long as they don't seem to have any problems with their sight.
There was a lack of consensus over when, exactly, a child should have his or her first eye exam, but a child should be seen relatively early in life.Many nursery schools have routine screenings of children, but some say those are inadequate. School screenings can be very deceptive, noting that some school nurses are not properly trained to perform a full eye exam and some children will cheat by peering at the charts beforehand.Family medical history can have an impact on when the first eye exam should be done.
