Why do I need two different eye exams for glasses and contacts? What is the difference?

When you require vision correction to see clearly, you may consider wearing glasses, contact lenses, or switching between both.

Some people have a strong preference for a particular style of eyewear. Others might not be aware of all the advantages that each variety can provide. There is no ideal option here; you should choose glasses or contacts based on your lifestyle and personal preferences.

Why contact lens exams cost more than standard eye exams may be a mystery to you. Remember that a prescription for glasses does not serve as a fitting for contact lenses. This is why a routine examination cannot replace a valid contact lens prescription. The additional procedures and testing needed to choose the best-fitting contact lenses are provided through a contact lens exam.

Examination for Eye Glasses

Regular comprehensive eye exams are required to obtain a prescription for eyeglasses. Your doctor will do tests to measure fluid pressure, prescription strength, ocular coordination, and vision acuity. In order to look for more significant health issues, your doctor may also dilate your eyes.

Contrarily, eyeglasses sit roughly 12mm from the eyes, which implies they will have a higher power than contacts. Exams for eyeglasses assess vision and determine whether any refraction correction is required.

Examination for Contact Lenses

Because contact lenses cover the eye, the examination is more involved. Optometrists who perform contact lens evaluations must assess the cornea’s curvature and diameter in addition to the true power of the lens. Exams for contact lenses also check if the lenses are the right size and have the optimum fit. To ascertain whether your eyes generate enough tears for contact lens use, a doctor could also offer a tear film evaluation test for first-time contact lens wearers.

Comfort is crucial when it comes to contact lenses. You’ll most likely be given a trial pair of contact lenses by an optometrist to see how they fit. In order to make sure the lenses fit correctly and comfortably, a follow-up visit is necessary. Your eyes’ general health may be impacted by contacts that don’t fit properly.


You should think about if you also need a prescription for contact lenses when getting your eyes checked. This necessitates further testing, which takes time. To avoid repeating the same steps, it is a good idea to have the same eye care specialist in Lake Worth perform both a general exam and a contact lens exam. Your contact lens and eyeglasses prescriptions are different, so don’t assume that if you have a prescription for eye glasses, you will be able to use it to purchase contact lenses and vice versa. 
The nice thing is that you don’t have to choose between eyeglasses and contact lenses! Schedule an appointment at Brightside Eyecare for both a contact lenses exam in Lake Worth and an eyeglasses exam. A Brightside eye test, for either eyeglasses or contact lenses, is just a call away.
