Frequently Asked Questions

  • Frequently Asked Questions

    1. Is a contact lens prescription different than a glasses prescription?

    Ans : Yes. When you order contact lenses, you must have a current contact lens prescription which specifies the power of the lenses, the size of the lens, the type and brand of lens.

    2. Can I wear soft contact lenses if I have astigmatism?

    Yes, you can wear a special type of soft contact lens called a tonic lens which will correct your astigmatism. However, these lenses are typically more expensive and there are fewer types available than there are with regular (spherical) lenses.

    3. Can I wear soft contact lenses if I need multifocals?

    Yes, there are a number of contact lenses designed for people who need bifocal (multifocal) correction. For examples:PureVision Multifocal, Soflens Multifocal, PureVsion2 for Presbyopia, Air Optix Aqua Multifocal and Biofinity Multifocal.

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

    The 2 weeks refers to the actual amount of wearing time so they can last a little bit longer than 2 weeks if you are not wearing them full time. However, should you have any concerns, please contact your eye doctor for advice(s) and follow their instruction(s).

    5. 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.

    6. 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 the 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.

    7. Do colored contact lenses work on dark eyes?

    Yes, they are called opaque contacts as opposed to enhancer tints which work only on light colored eyes. There are also several disposable colored lenses for dark eyes including Freshlook ColorBlends ; Freshkon ColorFusion and Freshlook Colours.

    8. Will coloured contact lenses look exactly the same colour on me like the one you show on your colour charts?

    It may appear slightly different since different people have different natural eye colours. But the one on the chart will give you a really good indication how it will look like.

    9. Can I swim with my disposable contact lenses on?

    It is the 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.

    10. 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.

    11. How good is our  price?

    We shop around the  retail and online competitors frequently and our prices are lower than the major retailers such as Wal-Mart, Costco, Lenscrafters etc.

    12. How long will it take for my lenses to arrive?

    90% of the orders will arrive in 5 business days within Canada and United States orders may take up to 7-10 business days after they are shipped out. However, if your lenses are backordered or specially made like Tonic, Multifocal or strong prescription, it may take another 3 to 4 business days.

    13. What are the expiry dates of the contact lenses?

    The expiry dates of the contact lenses vary depending on the brand. They usually vary from 2 years to 5 years.

    14. If both of my eyes are of different prescriptions, could I still purchase?

    Yes, of course you can. You have to purchase 2 boxes of different prescriptions.

    15. How could I know whether Lens4vision is selling authentic and safe contact lenses?

    Lens4Vision obtains its goods from reliable contact lens manufacturers and distributors. All the contact lens boxes are factory sealed and free of defects. The contact lens box would serve as proof that the contact lenses are authentic.
