Product Information

Boston XO2 contact lenses offer unparalleled fit, clear vision, and superior comfort. Made from a patented rigid gas-permeable (RGP) material, these lenses keep your eyes feeling fresh all day. Boston XO2 contacts are available in a wide range of parameters.

Features & Benefits

Boston XO2 contacts are RGP lenses indicated for daily wear. With proper cleaning and care, these contacts can last up to a year before they need to be replaced. This makes Boston XO2 contacts a great choice for the cost-conscious contact lens wearer.

Unlike soft lenses that take a one-size-fits-all approach, RGP lenses like Boston XO2 are made to order. This ensures that each Boston XO2 lens perfectly fits your eyes. When contact lenses fit properly, they are less likely to move or rotate during wear.

Because Boston XO2 contacts are custom-made for each wearer, they can address virtually any refractive error, including myopia (nearsightedness), hyperopia (farsightedness), presbyopia (blurred near vision), and astigmatism (blurred near and distance vision). Boston XO2 contacts can be made to correct irregular corneal conditions as well, including keratoconus and those resulting from unsuccessful LASIK procedures.

Another great thing about Boston XO2 contacts is they are naturally resistant to protein and deposit buildup. That’s because they contain zero water and are manufactured from a patented, ultra-smooth material that resists dirt and debris. This premium RGP material is also highly breathable, which means it allows plenty of nourishing oxygen to pass through to the eye. Our eyes need oxygen to stay white, clear, and healthy.

Boston XO2 contacts also retain their shape when you blink. This is why RGP lenses like Boston XO2 contacts typically provide sharper vision than soft, pliable hydrogel and silicone hydrogel lenses.

Additionally, Boston XO2 contacts are available in a variety of tints for easier handling during insertion and removal. These contacts can also be custom-made to include ultraviolet (UV) protection.

Who They’re For

Boston XO2 contacts are a great choice for people who are willing to go through a period of adaptation to contact lens wear. Because of their high oxygen transmissibility, Boston XO2 contacts are also ideal for people who struggle with dry eyes during lens wear.

Additionally, Boston XO2 contacts are suitable for some people with refractive errors (e.g., myopia, hyperopia, astigmatism, and presbyopia) for whom soft lenses don't produce the desired visual acuity.

RGP lenses like Boston XO2 contacts are also a good option for people with keratoconus, a progressive eye disease that may eventually result in loss of vision.

How to Put In Boston XO2 Contacts

Boston XO2 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.
