What Is A Refraction Eye Exam
A refraction eye exam helps your eye doctor figure out what prescription you need for glasses or contact lenses. To test this, your doctor may have you look into a machine that displays lenses of different strengths. By switching the lens in front of each eye while you read letters and numbers on a chart, your doctor can figure out which lens is best for you. This refraction test also helps your doctor to determine if you need a different strength lens in each eye.
What Is A Dilated Eye Exam
A dilated eye exam is the best thing you can do for your eye health! Its the only way to check for eye diseases early on, when theyre easier to treat and before they cause vision loss.
The exam is simple and painless. Your eye doctor will check for vision problems that make it hard to see clearly, like being nearsighted or farsighted. Then your doctor will give you some eye drops to dilate your pupil and check for eye diseases.
Since many eye diseases have no symptoms or warning signs, you could have a problem and not know it. Even if you think your eyes are healthy, getting a dilated eye exam is the only way to know for sure.
First Time At The Eye Doctor Heres What To Expect
Need to have your eyes checked, but youve never been to an eye doctor before? Heres everything you need to know before you go.
Maybe youve noticed that road signs are blurry or that you otherwise dont see as well as you used to. Maybe youre experiencing some other problems with your eyes or vision, or perhaps you just know that getting an eye exam is recommended.
Whatever your motivation for considering your first-ever visit to the eye doctor, know that its a great choice to make for your health. An eye exam is about more than checking how well you can see its also an opportunity to make sure your entire visual system, and even your entire body, is as healthy as possible.
How Do I Know Which Type Of Eye Doctor I Should See
Choosing an eye doctor can seem tricky because there are two types of eye doctors: optometrists and ophthalmologists. Both prescribe eyeglasses and contact lenses and are trained to diagnose and treat common eye problems. Learn more about their differences in this article.
Note that another type of eye care specialist, an optician, is qualified to fit your prescription eyeglasses and advise you on lens types and coatings. Opticians dont conduct eye exams or diagnose and treat eye problems.
Do: Bring Your Current Prescription Glasses And Contacts
Bringing your current prescription for glasses and contacts is always a good idea, as your eye doctor may want to test your vision in them. Its especially important if youre seeing a new eye doctor.
If you have a prescription card, be sure to bring it. Otherwise, have your information sent over by your previous eye doctor.

Dont Forget Your Glasses & Contacts
Make sure to bring your current eyeglasses and contact lenses. We want to test the strength and performance of your current corrective eyewear against any changes that may have occurred in your prescription. Human eyes can change significantly as we age, so dont be surprised if your glasses need replacing.
Dont forget to bring sunglasses either. By using special eye drops, the optometrist will dilate your pupils during a comprehensive eye exam. The primary side effect is light sensitivity for 4 6 hours. Remembering to bring a pair of sunglasses will help manage bright lights for the rest of the day.
How Eyeglasses & Contacts Work To Correct Your Vision
To understand how eyeglasses and contact lenses correct your vision, a brief understanding of how the eyes work may be helpful. The basic steps of vision are as follows:
- When you focus on an object, first light passes through the cornea, which is shaped like a dome and bends this light to help the eye focus.
- The light enters the eye through your pupil, and the amount of light that is let in is controlled by the iris.
- Next, this light passes through the lens of your eye. The lens and the cornea work together to focus light correctly on the retina, where turn the light into electrical signals.
- These electrical signals travel to the optic nerve and then to the brain, where the signals turn into the images you see.
If there is an issue with any of these steps, you may have trouble seeing correctly. A specific lens tailored to your needs can help correct your vision.

Wear Your Existing Contact Lenses Or Glasses
Be sure to come to your appointment wearing your contact lenses or glasses that are of your current prescription. Its important for your eye doctor to see if your current prescription is working for you and how it can be improved from there. Plus, if your glasses are able to be made same-day , many optometry centers will accept your old frames as a donation.
What Should I Expect After An Eye Examination
If youve had your eyes dilated, your vision will be blurry for several hours after the exam. Your eyes will also be more sensitive to light. For a few hours after an eye dilation, you should avoid driving, reading and looking at screens. Make sure to wear sunglasses to protect your eyes from the sun as your pupils shrink back to normal. If you dont need dilation, you can get back to your usual activities right away.
