Glasses In An Hour

Yes: You are likely drinking more water than is needed and your body is responding appropriately by excreting the excess water. ...Read more
Depends on...: It depends on factors like the size of the person, what the situation is (normal day, diarrheal illness, sports event, etc...), and how many cups/bottles of water a person is drinking throughout the day.

Optometry resubmit #: is it a legal requirement in florida that a person must have dilation of the eyes during a routine eye exam for glasses?
My eyes are blurry, and i'm seeing a glow around everything after being in a swimming pool for only an hour?
Corneal swelling.: You likely are experiencing some swelling in your cornea, the clear front portion of your eye, from exposure to the chlorine and salts in the pool water. If you open your eyes while in the pool and are not wearing a swimming mask or swimming goggles, this is more likely to happen. Your cornea is likely experiencing an osmotic accumulation of pool water from the corneal exposure to the chlorine. ...Read more
Yes: The latest opinion (& yet a very old opinion) is that protracted avoidance of a food more likely results in allergy than early exposure. Intermittent rather than routine exposure is also more likely to result in a food allergy.

Depends: Different states have different laws regarding the time acceptance of an eyeglass prescription. Typical is two years. Some optometrists will try and get you in each year to find a small difference and then sell you a pair of eyeglasses. This is why it is recommended to get most eye examinations from a real doctor - an ophthalmologist. ...Read more
My job forces me to sit in front of the monitor or laptop screen for more than 8 hours a day. Is it better to wear a powerless glass (zero power) to reduce the impact?
Glare: My assumption is that you're either talking about cutting down glare or you were told that computer screens were "bad for you." No study has linked computer screens to poor eye health other than getting some dry eye by keeping them open longer than usual. You can cut down glare by putting of those filtering screens over the screen. No need for glasses here. Hope that helps. ...Read moreSee 1 more doctor answer

Is it odd to have a loss of vision after looking at a computer screen for an extended period of time?
Very common: Blurry vision is common after extended computer use. Computer vision syndrome occurs when individuals stare at screens and increasing amounts of tear film evaporate causing dry eye. The dry eye can blur your vision. Additionally staring at one location for extended periods of time causes a strain in your accommodation that can cause blurry vision. ...Read more

However, many other causes are possible, ranging from trivial to quite severe. If these episodes occur in the absence of eye overuse, get checked out by an ophthalmologist. ...Read more
