Product Information

Boston XO contact lenses are rigid gas-permeable (RGP) lenses manufactured with technology by trusted eye care brand, Bausch + Lomb. Unlike soft lenses, RGP lenses like Boston XO lack water, which makes them more resistant to protein and deposit buildup. Boston XO contacts are made in a wide range of parameters and can be custom-made to perfectly fit your eyes.

Features & Benefits

Boston XO contacts are RGP lenses that can be worn daily for up to a year. To ensure the durability of these contacts, remove, clean, and disinfect them nightly.

Unlike soft lenses that take a one-size-fits-all approach, RGP lenses are made to order. As such, each Boston XO lens comfortably fits the natural shape of your eye. When lenses fit properly, they’re less likely to shift and cause vision disturbances.

Because Boston XO contacts are made for each patient, these lenses can address all kinds of refractive errors, including myopia (nearsightedness), hyperopia (farsightedness), presbyopia (blurred near vision), and astigmatism (blurred near and distance vision).

Boston XO contacts are also more resistant to deposit buildup than their soft lens counterparts because they’re made of hexafocon A, a fluorosilicone acrylate material with a high Dk rating of 100. This essentially means that hexafocon A allows high levels of oxygen to pass through the lens and into the eye to keep it white, clear, and healthy.

Like most RGP lenses, Boston XO contacts also retain their shape when you blink. This is why Boston XO contacts and other RGP lenses provide sharper vision than soft lenses. Moreover, Boston XO contacts help protect your eyes from the sun’s harmful UV rays. 

On top of that, Boston XO contacts come with a light blue tint so you can easily spot them in your contact lens case. This visibility tint won't change the natural color of your eyes. That being said, you can order Boston XO contacts in various colors, including blue, ice blue, violet, and green, if you want to try a different eye color.

Additionally, Boston XO contacts are less expensive in the long run due to their infrequent replacement schedule. 

Who They're For

Boston XO contact lenses are the best choice for people who are very discerning and are willing to go through a period of adaptation to contact lens wear. 

Like other RGP lenses, Boston XO contacts are also a good choice for some people with astigmatism for whom soft contacts don’t produce the desired visual acuity. They’re also great for people with keratoconus, a progressive eye disease that may eventually result in loss of vision.

RGP lenses like Boston XO are also suited for people who need contact lenses after refractive surgery.

Because Boston XO contact lenses come in various bright colors, they’re a great RGP lens choice for people who want to try a different eye color.

How To Put In Boston XO Lenses

Boston XO 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 rinse it with a multipurpose solution. Inspect the lens for any tears or debris. Using the middle finger of your dominant hand, pull down your lower eyelid. If necessary, use the middle finger of your non-dominant hand to pull your upper eyelid. Stare straight ahead and gently place the lens on your eye. Blink a few times to center the lens. Repeat this with the other lens. Don’t panic if the lens doesn’t feel comfortable as soon as you put it in. RGP contacts typically take longer to get used to wearing than soft lenses, but regular use is key for comfort.
