Choosing to wear eyeglasses or contact lenses for vision correction mostly depends on personal preferences. Lifestyle, comfort, convenience, budget, and aesthetics should all factor into your decision-making process. Before deciding between Annandale contact lenses and glasses, keep in mind that one is not necessarily better than the other; each has its pros and cons in terms of vision, ease of us, and eye health. In fact, the prescription eye exam will differ depending on if you want contact lenses or eyeglasses.
A routine eye exam is not the same as a contact lens exam. For contact lens wearers, a contact lens exam is necessary to ensure the lenses are fitting both eyes properly and that the health of the eyes is not harmed by the contact lenses. Before we take a closer look at what happens during a contact lens exam, let’s talk about normal eye exams. A comprehensive eye exam is an important part of caring for your overall health whether you need vision correction or not. By looking into your eyes, your doctor can check for signs of serious health conditions like hypertension and diabetes. During a your comprehensive eye exam, our doctor will look for signs of glaucoma, perform tests to check your vision sharpness, determine your prescription strength, examine how your eyes work together, and check the fluid pressure in your eyes. We may also dilate your eyes to see if you have any eye conditions or signs of other serious health conditions. If you wear or want contacts, you need an Annandale contact lens exam in addition to a comprehensive eye exam. Our eye doctor will perform special tests during a contact lens exam to evaluate your vision with contacts. The first test will measure your eye surface to determine what size and type of contacts are best for you. Your doctor may also do a tear film evaluation to make sure you have enough tears to comfortably wear contacts. With the results of those tests, your eye doctor can provide a contact lens prescription that is the right fit for your eyes. An eyeglass prescription is no substitute for a contact lens exam because the two are very different. An eyeglass prescription measures for lenses that are positioned approximately 12 millimeters from your eyes; whereas a contact lens prescription measures for lenses that sit directly on the surface the eye. An improper fitting or prescription of contacts can damage the health of the eyes.
Choosing the right lenses that are right for you depends on your vision and comfort. It is very important that your lenses are fitted correctly based on your prescription, eye shape, and specific needs.
