Contact Lens Exams

Contact Lens Image

At Vision Source of Howell, we strive to meet all of your eye and vision care needs. Corrective lens evaluations and prescription management are provided by our optometrist in Howell. After a comprehensive eye and vision evaluation, Dr. John Muir will discuss the variety of contact lens options with you to select the type that best fits your vision needs and lifestyle. If you suffer from dry eye, allergies, or recurring eye infections, speak with our staff to determine whether contact lenses are right for you.

Many patients ask "Why do I have to have a contact lens exam every year? I see fine with my contacts". Dr. Muir has to take additional time to determine whether or not your contact lenses are fitting properly, evaluate the cornea for any abnormalities or changes, evaluate the need for possibly changing into a better material for your eye health, discussing new contact lens technology with you, ensuring the contact lens prescription is still adequate (this prescription is different than your glasses prescription), as well as any additional follow up visits to ensure the right contact lenses for your eyes (if needed).

There are different levels of contact lens examinations, depending on the complexity of the prescription and the lens indicated. Contact lens prescriptions, once finalized, are good for one year from the date the prescription was finalized, which is a national law. This is to protect your eyes from the risk of wearing contact lenses, which are medical devices. Follow this link to read the FTC Contact Lens Rule in detail:


Prior to prescribing contact lenses, Dr. Muir determines what level of vision correction you require. Refractive error (commonly known as nearsightedness, farsightedness, or astigmatism depending on the error) is evaluated by measuring how the eyes focus when a series of different lenses are placed in front of them. An optometrist may use either a phoropter or an automated instrument to take these measurements. To schedule an appointment for a vision evaluation with our Howell optometrist, call 517-545-2020 today.

Corrective Lenses

After determining the level of refractive error, Dr. Muir works with you to determine whether contact lenses or glasses are best for your lifestyle. If you suffer from certain conditions, such as dry eye or allergies, glasses may be the most comfortable corrective solution. Contact lenses are available in either soft or rigid gas permeable form. Contact lenses need to be changed daily, weekly, bi-weekly, or monthly, depending on what type of lens you select. Specialized contact lenses, such as bifocal contact lenses, are also available for patients with special eye conditions. Call us at 517-545-2020 if you are interested in learning if contact lenses are a good fit for you.

Cosmetic Lenses

Advances in contact lens technology have created great options for cosmetic and prosthetic lenses. Custom contact lenses can be created to camouflage any color variation or irregularity and produce a natural eye color. Cosmetic lenses are also available to transform your eye color. Call us at 517-545-2020 and speak to our knowledgeable staff if you are interested in modifying or changing your eye color with contact lenses.
