Not everyone understands just how important it is to have regular eye exams—especially if their vision seems fine! However, regular eye exams can help you avoid problems later in life. Here’s what you should know.
A Vision Screening Doesn’t Always Cut It
While vision screenings and eye exams often overlap, they’re not the same thing. Vision screenings test just that—your vision—not your overall eye health. You’ve probably had a vision screening when you went to an eye care facility to get or renew a prescription for contacts or eyeglasses.
Vision screenings consist of testing your vision, but often do not go any more in-depth than that. An eye exam, however, is much more extensive. In addition to detecting subtle vision issues, an eye exam can also help identify conditions and diseases that can cause your vision to deteriorate later in life.
Eye exams, not vision screenings, are also responsible for finding indications that you may develop cataracts, a detached retina, macular degeneration, or glaucoma. Even seemingly non-eye related conditions like diabetes or high blood pressure can be revealed. A skilled doctor may even notice an increased risk of stroke, due to the fact that eye exams include the close inspection of delicate structures and blood vessels in the eye.
Children Also Need Eye Exams
Vision screenings are routinely given through schools and other programs, and these can be very helpful for ensuring that children’s vision problems are detected early on. That does not mean, however, that parents shouldn’t schedule their children for an eye exam. In fact, they should learn more about an eye check-up in Singapore.
First, vision screenings aren’t as thorough, as explained above. Second, volunteers often conduct them, which means that even mundane issues can be missed. Your child should undergo a thorough eye exam conducted by an expert on a regular basis.
What Does an Eye Exam Entail?
Modern eye assessments and consultations take approximately two to three hours. These tests use a variety of different types of equipment to examine your eyes and assist the doctor in making a diagnosis.
Some of the machines used today can map the cornea with precision, while others can determine the thickness of the cornea. The doctor can use other gadgets to diagnose eye injuries and irregularities. Combined, these technological advances can provide you with a perfect vision correction plan and help you stay healthy.
Other Things You Should Know
Before you schedule an exam, there are a few things of which you should be aware. For example, wearing your contact lenses is not recommended, and you will likely be unable to wear them for the rest of the day. For this reason and others, your doctor will probably suggest that you bring your glasses to the appointment.
Sometimes eye examinations require the dilation of the eyes. Your doctor will do this by putting drops into your eyes that increase the size of your pupil. This will make you extremely sensitive to light for several hours following your exam.
However, dilation doesn’t only make your eyes more sensitive to light. It can also have an effect on your near and far vision.
If your doctor is planning to do a dilation, it may be more comfortable to schedule your exam at the end of the day, or to take the day off from other responsibilities after your appointment. Also, know that driving may be difficult or impossible in the hours immediately following dilation.
