Your contact lens exam will stem from your prescription from the Standard Eye Examination. However your glasses prescription does not match your contact lens prescription. After your comprehensive contact lens exam you will receive two prescriptions - one for your glasses, one for your contact lenses.
What’s different about the contact lens prescription that my glasses prescription doesn’t cover? Your contact lens prescription will include information about the type of lens (soft, hard, scleral, or other specialty lens), and the shape and size best suited for your eye (curvature, diameter parameters of the lens). Your contact lens prescription is optimized for comfort, vision, and daily tasks.
All eye exams begin with a comprehensive exam that includes a prescription for glasses. Contact lens exam requires the Optometrist or Ophthalmologist to transpose your prescription to accommodate an optimized and comfortable contact lens experience. Your contact lens prescription considers comfort, vision, and daily tasks. Contact lens eye exams usually require a follow up exam for patients new to contact lenses and patients that are experiencing a change in prescription. Depending on the prescription and contact lens type, contact lens exams may require multiple visits to assure patient needs are met. Some first-time or beginners to contact lenses may need several training sessions.
Based on the amount of astigmatism you have, you may need toric lenses to maximize the clarity of your vision through contacts. Toric contact lenses have special markings on them to show if the contact lens is aligning correctly on the eye. If the contact lens is not in alignment, blurry vision may occur and a different contact lens brand or prescription may be needed. This is one reason why glasses and contact lens prescriptions may not be the same. Another reason glasses and contact lens prescriptions may not be the same is that while glasses can be made to very specific degrees of astigmatism (i.e. -2.00 x087), soft contacts come in pre-fabricated amounts of astigmatism (typically -0.75, -1.25, -1.75, -2.25) and offer an axis every 10 degrees (i.e -1.75 x080 or -1.75 x090).
Patients who have high refractive error (especially astigmatism), or keratoconus, or other corneal diseases or degenerations will benefit from a medical contact lens examination. Because the cornea is an important refractive surface, any corneal irregularities can cause blurred images, ghosting, and uncomfortable glare. After careful evaluation of the cornea, a specialty lens can be fitted to improve visual clarity better than what can typically be seen with glasses alone. Rigid lenses can be made very specifically to fit the curvature of the eye. Scleral lenses are specialty lenses that vault the irregular cornea entirely, offering a smooth refracting surface.
There are different types of contact lenses available to accommodate eye conditions and patient preferences. Each type of contact lenses serve a unique purpose to help patients with achieving maximum visual acuity. It is always important to consult with a vision physician to evaluate the health

After taking careful measurements and determining the health of your eyes, your doctor will select and choose a pair of trial lenses that would work best with your eyes. A trial lens is included with every contact lens exam with us. After placing the lenses on, the doctor exams the fit, movement and tearing in your eye. The doctor’s goal is to confirm good vision, fit, and comfort. If the lenses do not appear to be a good fit, the lens or prescription can be adjusted and another lens fitted. Once the lenses are fit, you can keep the trial pair and your contact lens prescription will be finalized and ordered. It is common to schedule a follow-up appointment to check that your updated or new contact lenses are comfortable, fitting properly, and providing good vision.

"If you ever need a testimonial for your repairing of glasses, feel free to use my email address, name, or phone number. After receiving my repaired glasses, it is really not fair to call them repaired. The truth is, my glasses were totally reconditioned. In the interim between the time I was sending you an updated Rx for new lenses, to replace the scratched one in my glasses. I found that the VA now will replace damaged glasses… They arrived 2 days after your refurbished pair. There is NO comparison between the new pair, and your refurbished pair. After trying both pair of glasses,.." Pete D
"Whether you walk in off the street or shoot them a call, World Optic offers an incredible service with a "clear vision" of customer satisfaction. I have just recently ordered my 5th pair of glasses with them and each time I keep coming back because they stand behind their products and craftsmanship… There are not enough good things I can say about this crew, but just know that if you ever have a question, need an opinion or just want to make a hassle/pressure FREE order, then this is your one stop shop! They do it ALL at World Optic and they do it well." Your loyal customer,
