Default Are these RGPs the same or different?


I've worn contacts for years until I began having dry eye problems and thought my lens-wearing days were over. Then I found a doctor who prescribed Boston EO lenses and I was overjoyed to find I could wear contacts all day again. I've now worn Boston EO contacts for at least 3 years. April 2016, I had an annual exam and ordered another pair of Boston EOs (exactly the same prescription), since I knew I'd eventually need them. The doctor said my old lenses would probably last another year or slightly less, so I've just been storing the new lenses for later and wearing my old pair.

But last week, I decided to try out the new lenses "just in case" before the year ends. I was upset to find that these new lenses feel so horrible I can't manage more than a few miserable hours of wear. They feel really dry and like they're scraping my eyeballs. I also have light reflection issues while wearing them that affect my vision in a bad way. With all that going on, I can barely keep my eyes open let alone see. Initially I thought it was allergies or maybe something with my eyes, but the problems completely disappeared when I switched back to my old lenses (the ones that are definitely Boston EOs).

I've wracked my brain trying to figure out why these new lenses feel so awful when they're supposed to be identical to what I've been wearing. Then, yesterday, I thought to look at the sticker on the back of the case these originally came in and that's when I noticed it says "Optimum Comfort" and not "Boston EO" like the other cases my new lenses have come in before. While the prescription numbers are all the same as my old pair, the inventory (?) numbers on the new case are different too. So, whereas my old cases say "Boston EO" with the number "13038PTC002" listed for both lenses, the new contacts case not only says "Optimum Comfort," but has "OD, M003759" and "OS, N000521" as the numbers listed.

I can't find a definitive answer online as to whether these lenses are different from Boston EOs. I was able to find a Dk (Fatt) chart online that listed Optimum Comfort at 65 Boston EO at 58...could this be why the new lenses feel so dry and "scrapy?" I've left a message with the doctor's office but won't hear from them 'til tomorrow. In the meantime, I'm thinking either the doctor's technician (who was new on the job) ordered the wrong thing or the lab sent the wrong thing, but I'd like independent verification of my suspicions...

Is "Optimum Comfort" a completely different type of contact lens from "Boston EO?"

Thanks in advance!
