Frequently Asked Questions

Top FAQs

  • If my 2 week disposable lenses are still comfortable and in good condition beyond 2 weeks, can I continue to wear the same pair?

    In order to maintain optimal eye health and comfort, it is important to adhere to the wearing schedule prescribed by your doctor. The main advantage of wearing disposable lenses is that you are putting a fresh new pair of lenses in your eyes every 2 weeks. Also, the convenient cleaning regimen of a disposable lens is only adequate for a 2 week wearing schedule.

  • If I only wear my 2 week disposable contacts part time, do I still have to replace them every 2 weeks?

    No, the 2 weeks refers to the actual amount of wearing time so they can last longer than 2 weeks if you are not wearing them full time.

  • Your website lists my lens as 2 week disposable, but my doctor says I can wear them for 4 weeks. Which is correct?

    The lens wearing schedules on our website are provided by contact lens manufacturers. However, doctors may decide on a different wearing schedule (shorter or longer) for an individual patient based on wearing habits, lifestyle, cleaning methods etc. You should always follow the wearing schedule prescribed by your doctor.

  • What's the difference between rigid gas permeable (RGP) lenses and soft lenses?

    RGPs are smaller and made out of a harder, less pliable material than soft lenses which makes them less comfortable initially. RGPs correct some astigmatism whereas soft spherical lenses do not.

  • Can I swim with my contact lenses?

    It is best if you don't because there are bacteria in the water that can adhere to your lenses and cause infections. If you do swim in your lenses, you should wear goggles over them and you should disinfect them immediately afterwards.

  • Why is it necessary for contact lens wearers to have regular eye exams even if their prescription hasn’t changed?

    Regular eye exams are important not only to check your prescription but also to evaluate the health of your eyes. This is especially important for contact lens wearers because the contacts could be causing damage to your eyes without necessarily causing any obvious symptoms.

  • I wear contact lenses and in order for me to read, I have to wear reading glasses over them. Are there any other alternatives whereby I don't have to wear glasses at all?

    Yes, the most common option is called monovision where one eye is corrected for viewing distant objects and the other eye is corrected for reading and close work. Monovision is a good solution for some people, but not everybody can successfully adapt to the arrangement. Another alternative is bifocal contact lenses which are available in both rigid gas permeable or soft lens designs.

  • Do colored contact lenses work on dark eyes?

    Yes, they are called opaque contacts. Year-long (daily wear and extended wear) opaque contacts are available in many different colors and shades. There are also several disposable colored lenses for dark eyes including Freshlook Colors.

  • How long does it take for my lenses to arrive?

    98% of all US orders arrive within the 7-10 day delivery time stated on our website. However, the vast majority of orders that are shipped from stock will arrive significantly sooner.

  • Can I use my glasses prescription to purchase contact lenses?

    An eyeglass prescription is not a contact lens prescription, and cannot be used to order contact lenses and vice versa. Each prescription contains information that is specific to the type of correction. Contact lenses sit directly on the eye whereas glasses are worn on the bridge of the nose. The distance between these two spaces dramatically changes the level of correction for each type. Also, not everyone who needs eyeglasses can wear contact lenses.

  • Can you recommend a doctor if I don’t have a current prescription?

    MESVision partners with a large network of providers nationwide. Please visit and use our Find A Provider tool to find a doctor near you.

  • Is a prescription required to purchase reading glasses?

    No. Reading glasses are available in standard, select powers, typically ranging from +1.00 to +4.00.

  • What is the difference between a routine eye exam and a contact lens exam?

    Routine eye exams are an important preventative measure for maintaining your overall health and wellness. During an eye exam, an eye doctor will look for vision problems including signs of serious medical conditions such as glaucoma, cataracts, diabetes, hypertension, etc. During a contact lens exam (fitting), an eye doctor will perform special tests to evaluate your vision with contacts. In addition, the surface of your eye will be measured to determine what size and type of contacts are best for you. A specific contact lens prescription will be written once the eye doctor determines which type of lens is best. The prescription is different than the glasses prescription you may have received during your visit or in past visits.

  • Can I wear soft contact lenses if I have astigmatism?

    Yes, you can wear a special type of soft contact lens called a toric lens which will correct your astigmatism.

  • Can I wear soft contact lenses if I need bifocals?

    Yes, there are a number of contact lenses designed for people who need bifocal (multifocal) correction.

  • Do I still need a prescription if I just want contacts to change my eye color?

    Yes, you still need to be fitted for the lenses even if you don't need vision correction. This is because contact lenses are medical devices and wearing them can affect the health of your eyes.

  • How can you offer such low prices on contact lenses?

    We can offer low pricing because of our large purchasing power. We are able to negotiate the best possible pricing from contact lens manufacturers and distributors. We simply pass those savings along to our customers.

  • How do I read my eyeglass prescription?

    While you don't need to completely understand how to read your eyeglass prescription to place an order, you'll need to know the basics in order to select and order the right lenses for your eyes. If you don't have a copy of your prescription, or are not sure how to read it, rest assured that as long as you have your doctor's information we can contact your doctor directly in order to obtain your correct prescription.

  • I want to purchase eyeglasses, but this prescription stuff is confusing. Is there an easier way?

    Absolutely! You can always leave the prescription fields blank when ordering, and then either send us a copy of your prescription, or give us your eye doctor's contact information and we will collect your prescription information directly; ensuring that your prescription is correct while you remain free of worry!

  • What is the difference between Bifocal and Progressive Bifocal?

    Bifocal eyeglass prescriptions were originally only able to be corrected with lenses called lined bifocals; these types of glasses have a visible line at the point where the prescription changes from near to far vision. Progressive Bifocals are lenses that have no visible line and gradually change from near to far vision in a way that is easier for your eyes to adjust to. MESVision currently only offers Progressive Bifocal lenses. Unless your prescription notes "Bifocal Only" or "No Progressives", then you can use your Bifocal prescription to place an order for Progressive Bifocal lenses.

  • What if my doctor says I need Bifocal correction in only one eye?

    MESVision is only able to process orders with one type of lens per frame. Since a prescription with bifocal correction in only one eye would require a progressive lens in one eye and a single vision lens in the other, we are unable to fulfill these types of orders. We apologize for the inconvenience.

  • My prescription has expired or it doesn't have an expiration date, can I still order glasses?

    We can only fill orders for unexpired prescriptions. If your prescription does not have an expiration date, then the expiration date is either 1 or 2 years from your exam date, depending on your doctor's preference. We will verify your prescription with your doctor and notify you if the prescription is expired. Some doctors offer prescription extensions if your current lenses have broken. We must verify these exceptions through your doctor though.

  • What happens if my doctor changes my prescription after I receive my glasses?

    If your doctor changes your prescription due to vision problems you are experiencing with your recent glasses purchase, we will replace your lenses one time for free. You must return the frames to us within 30 days from the delivery date. The replacement lenses will be made with the same lens material and treatments that were previously selected, and will require you to mail-in your existing frames, though we will provide you with Free Return Postage.

  • What are the best eyeglass lenses for my prescription?

    Choosing lenses for your new glasses has a lot to do with preference, but some lens materials and treatments are better for certain lifestyles and prescriptions. You can read over the lens options to find the best fit for you.

  • What is pupillary distance (PD)?

    Pupillary distance (PD) is the measurement (in millimeters) of the distance between the centers of the pupils of your eyes.

  • Why is my pupillary distance (PD) measurement needed?

    Pupillary distance is an important measurement used to determine the proper lens shape and alignment of your prescription correction to your line of vision. Without an accurate PD measurement, correcting vision can be difficult since lenses need to be aligned over the center of your pupil for proper clarity.
