• Can the flu cause vision problems?

  Headache are one of the symptoms of flu, but your vision problem may be cause by the attack of the flu virus or if you are allergic to some of the medication that you take for the flu. Go and check it at your eye doctor.

• Do too much stress cause your vision to be blurry and make you feel dizzy?

  Yes, stress is one of the causes of blurry vision and dizziness. Just as stress causes tension in your neck and shoulder muscles, stress can also cause tension in your eye muscles, which reduces the automatic eye movements and interferes with your ability to focus.

• Is vision insurance necessary for young chilren?

  If your child is not with current vision issues or you don't have a family history of vision problems, vision insurance is usually not needed for 3- and 4-year-olds since they only visit the optometrist once or twice during those years.

• Can contact lenses be different powers for left and right eye?

  It is quite common to have different powers in different eyes and you can get contact lenses with different presctiption for different eyes too, but make sure never wear contacts for left eye on your right eye, contacts for eight eye on your left eye, otherwise, your vision will be effected.

• Can I use my contact lens prescription to buy my eyeglasses?

  The answer is definitly NO. Eyeglasses are usually placed at about 12 millimeters away from the eye while the contact lenses are placed directly on the tear film of the eye, the prescription on the contact lenses should be less nearsighted than that of eyeglasses. You can go to your eye doctor to have your eyes checked to see the exact difference.

• Is there any place I can Buy Lenses Only To Fit Into My Old Glasses Frame?

  You can take your glasses to the local optical store and find the lenses are fittable for your old frames, then ask the optician to process it for you, but I think some of them are unwilling to do so for they will take a risk of breaking your old lenses when getting them out and putting new lenses in. Actually, it is also hard to find lenses that are available for your old frames, the best way to slove your problem is to buy another pair of glasses.

• Can I use old lenses from to fit my new frame?

  Probably, you can do it like this, but you should carefully choose the frame that can fit your lenses well. The frame only holds the lenses and the lens is mounted in such a way that the centering is exact to your iris.Otherwise, the lenses may pop out or give you an unclear vision. It is much easier for you to get another new pair of glasses.

• what is pd on prescrption for eye glasses?

  PD stands for Pupillary Distance, which is the distance between your pupils in millimeters, Your PD is very important for accurately fitting your lenses to achieve vision acuity. 1. PD (OU), written as ""62"", means the Binocular PD which is for both eyes. 2. PD (OD), means the Monocular PD for the right eye, PD (OS), means the Monocular PD for the left eye, A Monocular OD is written as two numbers, for example ""32/30"", ""32"" represents the PD for the right eye, and ""30"" for the left eye. 3. Sometimes PD is written as ""62/59"" or they are labeled ""Far"" and ""Near"". Your PD is usually measured for distance vision, which is 'Far PD"", or ""62"" in this example. For reading glasses, doctors measure your ""Near PD"" or ""59"" in the example. 4. Always enter your ""Far PD"" for distance vision eyeglasses and enter your 'Near PD"" for your reading glasses only. For most people, the difference between Far PD and Near PD is about 2-3mm. Source: http://www.firmoo.com/help-p-30.shtml
