Product Information

Boston EO contact lenses deliver exceptional visual acuity and outstanding comfort. Made of a patented and highly breathable lens material, these rigid gas-permeable (RGP) contacts stay fresh and comfortable all day. They’re made in a wide range of parameters and can be custom-made to perfectly fit your eyes.

Features & Benefits

Boston EO 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 EO lens offers exceptional fit and clarity. When lenses fit properly, they’re less likely to shift and cause vision disturbances.

Because Boston EO 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).

Compared to hydrogel and silicone hydrogel lenses, Boston EO contacts are more resistant to protein and deposit buildup. This is because they’re made of a patented, ultra-smooth material that doesn’t contain water. Known as enflufocon B, this material allows plenty of oxygen to pass through the lens and into the eye so that it stays white, clear, and healthy.

Boston EO contact lenses also have a bi-aspheric back, which ensures all-day comfort. Plus, like most RGP lenses, Boston EO contacts retain their shape when you blink. This is why Boston EO contacts and other RGP lenses provide sharper vision than pliable hydrogel and silicone hydrogel lenses. 

Additionally, Boston EO contacts come with a light blue tint so you can easily spot them in your contact lens case.

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

Who They're For

Boston EO 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 EO 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 EO are also suited for people who need contact lenses after refractive surgery.

How To Put In Boston EO Lenses

Boston EO contacts are RGP lnses 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.

Product is equal in quality as lens purchased from my eye care professional at far less cost.

Also product came in far less time that suggested.

Will certainly order from you when replacements are needed.

One of the contacts sent was defective was lost

I order two contacts at a time and have two sets. I switch them weekly. After wearing the one for a week. I noticed the second one hurt when I first put it in my eye. I tried to let it settle in for several hours but eventually it just spontaneously popped out on its own and was lost. I have not had this issue with your contacts before and have been ordering them for several years at least. So I was disappointed.

Best regards,

Karl Weikel

Everything fine!

I use this lens already 20 years may be. Thanks!


Happy customer

Service is fast and has always delivered a quality product. I still wear gas permeable lenses and they are a little hard to find....but not for!
