During a contact lens exam, the cornea Eagle Eye 911 Review surface is the center of the exam. The doctor runs tests to assess the cornea to get the right fit for the contact lenses. An instrument measures surface and curvature of the eye. It works like a digital camera that takes pictures of the eye and creates mathematical depictions of the curvature of the cornea surface. This gives the doctor the sizing for the contact lens. A microscope is used to determine the health of your cornea and your pupils may need to be measured if you are being fit for bifocal contact lenses.Your tears may be measured with a tear film evaluation to determine the amount of eye moisture in the eye as well as a fluorescent dye that is placed in the eye to see the quantity of tears present and any cellular compromise to the cornea. Careful attention is paid toward analyzing the eyelid margins and the clear tissue covering the white part of the eyes and under the eyelids for any signs of eye disease or problems that may interfere with successful contact lens wear. After testing, the doctor will select a contact lens that best matches your eye. This lens is usually fit for a trial period to make sure your eyes are adapting in a healthy manner.

Having no backup option when away on a trip they continue to wear their lenses and the end result can be scarring and eye damage. Always having a backup pair of spectacles is priceless in preserving your eye health.. This is even more important with teens and children who tend to not complain until their eyes are already in an advanced state of compromise. Because they are more concerned with appearance at certain ages, they are much more reluctant to understand the necessity of eyeglasses as an emergency preventative health device. Contact lenses are a medical device controlled by the Food and Drug Administration and should be given the care an respect as any other medical device. Part of this care is an annual eye exam that assures your eyes are continuing to have a healthy adaption to this marvel of technology, first envisioned by Leonardo da Vinci in the 16Th century.
