There are many reasons you should choose to get an eye exam. Checking visual acuity, diagnosing for eye disorders, and checking your child for any developmental problems are three excellent reasons to visit your optometrist.
Visual Acuity
The eyeball takes in light rays and deflects them onto the retina in the back of the eye. In the normal eye, this deflection projects the image exactly onto the retina. If the eyeball is either too long or too wide, the image is projected either in front of or behind the retina, causing a reduction in acuity. If the eyeball is too long, and the image is projected behind the retina, the eye is said to have hyperopia, or be farsighted. This person can see far objects normally but has difficulty seeing objects close up. If the eyeball is too wide, the image is projected in front of the retina. This produces a condition called myopia, and the eye is said to be nearsighted. This person can see near objects normally but cannot see objects well at a distance. Visual acuity can be corrected with external lenses, either as glasses or contact lenses.
Developmental Problems
Children who have uncorrected vision problems often experience learning disabilities and can cause permanent loss of vision if left untreated. Strabismus is a misalignment of visual axes that can involve one or both eyes. The end result can cause esotropia (cross eye), exotropia (walleye), or amblyopia (lazy eye).
Diagnosis of any of these disorders must be made by an examination. Therefore, it is in your best interest to get vision checked at least every 1 to 2 years.
What Purpose Does an Eye Exam?
Well, the eye is one of the most important parts of your body. It is essential to protect the eye and keep it in good shape.The best way to determine the condition of the eye is to undergo regular eye exams.
We found out this evening that the babies’ eye exam will be repeated tomorrow. We are not really sure why - only know that there is an order for it so there must be cause for concern.
How often should have an eye exam?
I was wondering how often I should have an eye exam. I am 18 and got glasses last year for driving and distance because I am nearsighted. Your optician should have advised you when you should be checked.
