Product Information

Boston IV contact lenses from Bausch + Lomb are rigid gas-permeable (RGP) lenses that keep your eyes feeling fresh and comfortable all day. Each Boston IV lens is made specifically to meet the needs of your prescription and fit your eye perfectly.

Features & Benefits

Boston IV contacts are RGP lenses that are designed to be worn daily. They can last up to a year before they need to be replaced as long as they are properly cleaned and cared for.

RGP lenses like Boston IV contacts are made to order to ensure that each lens perfectly fits your eye. When contacts fit properly, they're much less likely to move around during wear.

Boston IV contacts are custom-made to meet the needs of your prescription, which means they can address nearly every refractive error, including myopia (nearsightedness), hyperopia (farsightedness), presbyopia (blurred near vision), and astigmatism (blurred near and distance vision). To correct these visual impairments, Boston IV contacts come in the following designs: aspheric, bifocal, toric, bi-toric, front toric, and back toric.

Additionally, Boston IV contacts are naturally resistant to deposit buildup. That's because they have zero percent water and are manufactured from a premium RGP material called itafocon B. This material also has high oxygen transmissibility, allowing plenty of oxygen to reach the eye. Our eyes need oxygen to stay moist and healthy.

Boston IV contacts are available in clear, but they also come tinted in shades of Blue or Electric Blue. The tint makes it easier to see your contacts during insertion and removal. It won’t change your natural eye color.

Who They’re For

Boston IV contacts are a good option for people who don't mind going through a period of adaptation to contact lens wear. Because of their high breathability, Boston IV contacts are also great for people who experience dry eyes during lens wear.

Additionally, Boston IV contacts are suitable for people with refractive errors for whom soft lenses don't produce the desired visual acuity.

RGP lenses like Boston IV contacts are also a great choice for those who need vision correction due to irregular corneal conditions, like keratoconus and those resulting from unsuccessful LASIK procedures.

How to Put In Boston IV Contacts

Boston IV contacts are RGP lenses and as such, you should follow the standard procedure for this type of lens. Wash and dry your hands before touching the contacts or your eyes. Scoop your first lens out of the case with the index finger of your dominant hand and rinse it with a multipurpose cleaning solution recommended by your eye care professional (ECP). Inspect the lens for any tears or debris. Hold your eyelid open, stare straight ahead, and gently place the lens on your eye. Blink a few times to center the lens. Repeat for the other lens. Don’t panic if the lens doesn’t feel comfortable immediately. RGP lenses typically take longer to get used to wearing than soft lenses, but regular use is key for comfort.

Boston IV FAQs

How many boxes of Boston IV do I need to buy to last 6 months, or 12 months?

You need 1 box(es) of Boston IV contacts to last you for 6 months. In order to last you for 12 months, you'll need 1 box(es). These amounts pertain to a single eye, so to cover both eyes, double these amounts.

Can you take a nap in Boston IV contacts?

No, you cannot nap in Boston IV lenses. As Boston IV are not approved for overnight wear (a full night's sleep), napping in them for a short period of time is not advisable either, and it can lead to eye-health complications.
