What is normal internal eye pressure?

Although normal intraocular pressure is generally considered to be below 22-24 mmHg (millimeters of mercury), there is much variability in "normal" for different persons.  One person may have an IOP (intraocular pressure) of 28 and not have glaucoma, while another may have an IOP of 16 and have severe glaucoma (so-called "normal or low tension glaucoma).  Bottom line is that all persons at risk for glaucoma (everyone over 50 years of age, and anyone who has a family history of glaucoma) should be examined by an eye doctor at regular intervals.\n\nThe "right time for laser treatment" is unique to each patient and determined by severity of glaucoma, response of IOP to medical treatment, and other factors which require evaluation by an ophthalmologist (eye physician & surgeon).

Differs depending on age and health, but on average for a normal eye the minimum focal distance is 10cm

You won't find them with a -2.75 BC (base curve).  -2.75 is the power.  The base curve will be a number like 8.3 or 8.6.  If you're confused about your prescription, you should talk to your eye doctor.

It doesn't only occur in diabetics.  *I* have glaucoma.  My mother was diabetic and did not.  My father was not diabetic, but he and 2 or his 3 siblings also had it.  It is or can be inherited.  If caught early enough and treated, many people have no obvious problems.  It has nothing to do with glasses.  My father died at 81 and never wore glasses.\n\nGlaucoma is a build up of fluid that causes the pressure in the eyes to rise.  In most cases, it is treated with drops.  I just recently started Lumigan.  In extreme cases, an ophthalmologist might recommend surgery to relieve the pressure.  The pressure in my eyes is about twice what it should be.  It scares the hell out of me, but I'm being optimistic.\n\nIf you suspect a problem, see an ophthalmologist, NOT and optometrist or optician.  They are not qualified in this matter.  Be sure to see a doctor who can administer a Visual Field screening.  This is to track vision loss.  (As the pressure builds, a person with glaucoma usually loses peripheral vision.)\n\nI hope this helps.

Depending on the institution 70-110 or 80-120 is normal.  If it is just a little over, keep an eye on it, but yeah, consistently higher than that, you need to see your doc.

Hi there,\n\nThe viewing distance from the screen to the eyes should be seventeen to twenty-six inches. \n\nSome eye relaxation exercises would also help.\n\n:)

A "normal" blood pressure is considered to be 120/80 by most standards. But, like blood glucose, it is unique to the individual as to what your body will tolerate before you start showing signs / symptoms. Be sure to monitor your blood pressure regularly at home and record your findings to share with your doctor.

Normally between 5-7 liters, depending on the size of the person, or 7-8% of the persons body weight

I wouldn't worry about it, your blood pressure is in the normal range. Normal for an adult is 120/80.

Wearing contact helps - coz ur center does not change - and has more sharp / focus than glasses.\nIf u follow eye related healthy diet/exercise - u can get by with a smaller no, like  -1.75 for starter, and help it reduce further (coz ur eye will not suffer strain from change of optical centers, etc - as is with glasses...\nTheoretically, one cannot go beyond 20/20, it is perfect vision...

you should definitely see an optometrist so they can tell you whats going on they will prob take your interocular pressure and also may take photos of the back of your eye if you have floater and halos you could prob have glaucoma or diabetic eye they may even do a visual field on you

Prehypertension is defined as having systolic blood pressure (the top number in a blood pressure reading) of 120-139 points or a diastolic blood pressure (the bottom number) of 80 to 89. A person's blood pressure is considered high if the systolic pressure is over 140 or the diastolic is over 90.

Go to your eye doc I didn't even know they made a strength of 4.00!

THE DOCTORS LET THE PEOPLE TO LOOK IN THE "SNELLEN CHART" WHICH IS A TEST..YOU WILL JUST LOOK AT THE CHART AND TRY TO READ THE LETTERS WRITTEN IN IT..THE LETTERS HAVE DIFFERENT SIZES..NORMAL VISION IS 20/20 VISION..LOWER THAN 20/20 LIKE 10/10 IS A GREAT VISION..HOWEVER..HIGHER THAN 20/20 MEANS THAT YOU HAVE POOR EYESIGHT.

Doctors dilate your eyes to be able to see the back of the eye (the retina).  It's important that the retina is healthy and functioning properly.  If you have glaucoma or high intraocular pressure, your doctor may not want to dilate you (it may induce angle closure glaucoma in at-risk patients).  It's also not a good idea if you have very high blood pressure.  As far as common side effects, your vision will be blurry for 3-4 hours after the drops and you may be extra light sensitive for that time.

For all adults in general, the medical guidelines are:\n\nLess than 120/80 = ideal, healthy blood pressure.\n120/80 to 139/90 = still in the normal range, but verging on hypertension.\n140/90 to 159/99 = Stage 1 Hypertension (this is when your doctor will say you have high blood pressure).\n160/100 and above = Stage 2 Hypertension (SEVERE high blood pressure). \n \nAs a person gets older, their systolic blood pressure (the top number - ie: 120 in 120/80) will get higher, and their diastolic blood pressure (the bottom number - ie: 80 in 120/80) will get lower.  This is expected as a normal person ages.  However, just because it's "normal" doesn't mean it's healthy.  The 70 year old woman who has the typical 137/65 should still see her doctor about getting her blood pressure closer to 120/80.  The heart is going to need more help as a person gets older, and no matter what age the person is, the heart always works best when blood pressures are close to 120/80.  Hope this helps.
