I've got -2.75 & -1.75 eyes. Should I round up or down to the nearest diopter? For each eye. 2.5 or 3 for the 2.75 eye & 1.5 or 2 for the 1.75 eye?

Because of the difference I would suggest buying 1 pair in each of the diopters you need and swapping out the lenses. For me the difference was only 1 point so I went up a half. They've worked out great.

Two easy ways to solve this issue: There is a company called Platina (they also sell on Amazon) that sells the Corrective lenses separately so you can go that route if you like but it is more money. Second option: determine which is your DOMINANT eye and buy a pair with that correction. 99% chance you will NEVER notice the difference since your dominant eye controls most of your "vision"

So you have the option to have a different strength for each eye? I did not when getting swim goggles and went with something in the middle, so in your case, either 2 or 2.5. I have one eye too strong, one not enough, but that does not seem to be a problem.

Honestly there isn't a big deal between -3.50 and -3.00 and you can get either one and you will see grate. But if you are still not satisfied go for 2 pairs of one -3.00 and -3.50 and just switch lenses and this way you have to pairs with perfect match

These glasses actually do have a magnification of +.25. I actually took them to my eye doctor and they measured the power for me. To put this in perspective, many reading glasses are +1 magnification. +.25 is the smallest increment, incrementing at .5 .75 and 1. So, the magnification is quite small, it just helps things become a little clearer.

Depends on what your prescription is. The camera has a built in -3.0 to +1.0 diopter adjustment. You want to buy the one that will allow you to match your prescription. E.g. If you wear +2 prescription, get the +2 and dial it down by 1. You would only need the - if you have to go further than the -3 that is built in. However, I have found that I do not use the diopter. When I have my glasses off, the images on the LCD are blurry. So I shoot with my glasses or contacts, so I can still view the images on the LCD. Hope this helps you decide. Chris

I use the 3 and higher for imaging Planets, thet 2X can be used for doubling the power at the eyepiece. The 127 eq is a great scope you should have lots of fun. I had a C5 at one time loved it.

The CPC is listed as using 1.25" star diagonal. You should be able to use the 2" star diagonal in this kit to use the eyepieces in this kit. You will need to remove the 2" diagonal and reattach your 1.25" diagonal to use your 1.25" eyepieces.

I was lucky, because the loupes that I had prior to had the 2.5x written on them. It all depends on what you need for your working distance. I am five six and I work in a dental office. The 3.5 work great for me and so did the 2.5. If you are taller I would get a rep to visit you, and then order them through amazon. Through the reps their pricing is outrageously high.

The numbers 1.25, 1.5 etc refer to the maginification of the lens, the reading glass strength. The frames are all sized the same, for a unisex head shape. The temples are adjustable in length assuring a comfortable fit on a wide variety of head sizes. You'll need to know which power (+2.0? or +1.5? ect) you'll need for the lens of course. Thanks,

Being sincere, I'm not sure if that prescription will fit on the glasses but mine are 1.85-1.65 and they do. You should consult a proffesional and ask him if it worth the risk because they change the way you do sports.

i've found 1 1/2" is the "best". That close, always manual focus if possible.

I am not sure if you are asking how low can you go as in is there lower then 1.8, BUT aperture can go as low as 1.2 which is EXPENSIVE. 1.8 is just fine if you are thinking cost effectiveness.

You can choose between 60, 90 and 120 deg angles in the menu. Even the 120 isn't really fish eyed where as normal fish eye lenses distort around the edges. Hope this helps.

Id say pick the 17-35 if you intend to stay on DX size for another 5yrs... the 50mm covers the middle of the 24-70 so moving your feet will cover that distance, but the 17-35 will allow for group shots and landscapes/buildings... the 24 will limit that somewhat.... my2cents!

Hi Anthony,The correct magnifications are 1.5x, 2x, 2.5x and 3x. The magnifications in the current video needs to be updated. We sincerely apologize for any confusion.

I'd put it in the 1.4 group... I love this lens. Tact sharp and can focus up close to your subject.

My vision is not that far out however I have issues with small print and it is exactly what I use them for is reading. the multiple lens should give you a good match. I wear over my glasses also.

Some people with an astigmatism will see more than one dot or the dot will seem out of round. I am one of those people and you just get use to it over time. My aimpont and delta point do the same thing.
