Eye glasses prescription question

On my “taper” for possible Lasik surgery wearing my “new” glasses full time. They are driving me nuts and I can’t see well at night (very blurry and a bit of haloing). Never had a problem with my contacts (toric lense - astigmatism), which I’ve primarily worn for many years. Only time wearing glasses prior was between the bathroom and bedroom. Day vision is great.

I’m wondering if the Doc goofed my “new” eye glass prescription. I’m aware the sphere is different b/w contacts and eye glasses (esp at my poor nearsightedness, but what about the cylinder?

Contact cylinder is -.75 and -1.25 r/l
Glass cylinder is +1.50 and +.50 r/l

Curious if my Doc goofed and that + above should actually be a negative and perhaps if the glass cylinder r/l is swapped.

Any opticians out there?

Thanks

I’m not an optician, but as chance would have it, I just happen to have my prescription handy. I also have a pretty healthy astigmatism, and my glasses prescription is:

R: Cylinder -2.00 Axis 165
L: Cylinder -2.25 Axis 018

My contacts prescription is:

R: Cylinder -1.75 Axis 160
L: Cylinder -1.75 Axis 020

My guess is that your doc messed up the signs on the cylinder based on the above. But again, I’m no optrician.

Spot

I don’t know, but I feel your pain. I have an abrasion on my cornea and have to wear my glasses, no contacts for a week. It sucks.

Good luck with your lasik procedure, it seems like everyone I know that has had it done, loves it.

Your spectacle Rx can be written in PLUS or MINUS cyclinder. The phoropters (the thingys you look through with all the lenses that the doc flips) can be in PLus or minus cyclinder (astigmatism) . It gets confusing , and it would confuse you more if I explained it in detail…but the gist of it…is, for example, -1.25 diopter cylinder is the same as +1.25 diopter cyclinder, but the axis you see after the cylinder will be 90 degrees different. The sphere power (the first number on your RX), will also change depending …if your RX is in PLus or minus cyclinder.

Looking at your RX, your astigmatism power changed a bit…I would compare this to your prior Rx’s from years ago , from previous exams. Id also make sure your RX has been stable for a fe w years. Id alos have your RX checked again carefully beofer your surgery. The numbers shoud all be consistent and stable. If your not comfortable with your RX , make sure you ask your Doc about this, make sure he or she knows your not seeing well with this current RX. If your not comfortable with the answers seek another opinion before your surgery.

What happened? Ouch.

I’ve never had issues with my contacts, but going through this process has certainly been enlightening, regardless of the outcome. My appt is the same day as a Hall of Fame baseball player and a Hall of Fame Rock Star, so pretty sure I’m going to the right Doc. It’s not a “sure thing” until the final cornea reading prior to surgery. So, 3 weeks in glasses and it’s STILL not a for-sure procedure. Arrrghh…

If I had to wear glasses fulltime, I’d go insane (at my poor vision - 8.25 for glasses)

Everybody at work says “dude, those are some thick glasses…are you getting Lasik?” Dozens of people at work have had LASIK (some a long time ago). It appears “most” people had some sort of issue which took anywhere from a few weeks to 6 months to work out. Very few had no issues. The best advice I’ve heard was “be patient”, it could take some time. Everyone is different…although technology has gotten better. 100% have said it was a good decision. Of course, it’s hard to search the internet and not see the horror stories.

A friend thought that glasses’ cylinder are written in + format and contacts are written in - format, but wasn’t sure…so still wondering if Spot hit it on the head (doc was incorrect).

Thank you…very very much.

Another question if you have time.

My contact night vision was great…no problems.

My glasses’ night vision is horrible. Blurry with a bit of haloing. I “cheap’d out” and bought the FeatherWeight Plus from LensCrafters and trying to figure out why my night vision (with glasses) is so terrible.

Any ideas? Could it be:

  1. lens quality
  2. my terrible nearsightedness + glasses (-8.25)
  3. eyes haven’t adjusted
  4. spherical abberation (I don’t know what this really is, just at home searching the internet…which I’m sure is a Doc’s nightmare)

thanks!

Your vision with your specs is probably poor because of lack of good Anti reflective coating on your high minus lens. Also maybe poor centration (horizontal or vertical of the lens center over your pupil axis) …which can cause induced abberration. … …also maybe RX being off a bit…
