Contacts or glasses to jump?

[packerboy 3]

I've tried a couple.... it's a marketing ploy really. You can sleep in them yes, but it's not comfortable and not recommended.

Then again I have a friend that slept in normal soft lenses (not daily) that you are supposed to keep for a year. He just took them out once a month soaked them and back in they went.

Hi,

Excuse me for changing direction slightly here... but why do I gett better vision from my glasses than contacts (is this normal?) - I wear torics and find that I need to wear reading glasses too (for close work) but I'm O.K with my normal glasses.... I'd have thought that contacts would have been better than glasses... I guess that I'm wrong....

P.S I use my contacts for most sports (long distance stuff, like running, skiing, sky diving etc.. but cannt for squash - I keep missing the ball)

It's never recommended to sleep in lenses, like wearing the same pair of underwear non stop

Different lenses fit different people differently... corneal shapes, tear chem, etc all affect comfort.

It really isn't a marketing ploy at all... the new lenses (silicone hydrogels) allow 15+ more times oxygen through the lens as the older version of soft lenses. When you sleep, your cornea gets air from the blood vessels under the eyelid. Put a hunk of plastic there and you block the oxygen from getting to the cornea. The more air that can pass through the lens, the less chance of hypoxia or other corneal issues.

So no, there is nothing ploy-ish about it. I won't fit anything except si hydrogels to be slept in, because I'm not a big fan of patching up screwed up corneas due to hypoxia.

No one lens works for everyone, just because they didn't work for you doesn't mean they aren't great lenses. Also remember that environment has a lot to do with it as well, same with contact lens solutions. There are a lot of variables to address with contact lens fitting, it isn't so simple as plopping a lens on an eye.

You're excused
Is it normal to get better vision with glasses over contacts, yes and no. Depends on the person and prescription. In people with higher prescriptions, they see better with contacts due to improved optics peripherally in the lens compared to glasses. People with significant differences in Rx from one eye to the next also see better with contacts as the contacts even out the differential in retinal image size caused by the lopsided prescription.

You could see better with your glasses if...
-your contacts are not cleaned well (make sure you rub them when you take them out!)
- you overwear your lenses
- the lens rotates on your eye somewhat (this is fixable, see your eye doc)
-the rx needs to be updated (see your eye doc)
-the optics of that particular pair of contacts doesn't match up happily with the optics of your eyes (see your eye doc to address this too)

Why you can't read as well with contacts as glasses? My best guess is you are somewhere in the ballpark of 40 and nearsighted. You notice the effects of presbyopia (needing bifocals) sooner with contacts than glasses.

If you are not around 40 or nearsighted, it could be that the prescription is a bit too strong for you.

I'll tell you the same thing I tell my patients. If something isn't right, tell me so I can fix it. I can't fix problems that I don't know about. If you aren't 100% happy with the contacts, either vision or comfort wise, don't order any. There are many options out there, you have not tried them all yet
Sorry I can't give you anything more definitive than that, but you really should call your eye doc with those questions, since my guesses via internet are completely that... guesses.

Thanks Jen

Good stuff to take to my next opticians appointment.

(40+ and short-sighted)

Thanks for the advice. I think I will probably have a go with contacts, I still have just over 2 months to get use to them so I have nothing to lose.

Maybe a stupid question but I thought you had to have a certain amount of jumps before you can wear a full faced helmet in the UK?

I have been wearing contacts for all of my jumps and so far only lost one.
When I started using them (way before I started skydiving) it really took a while to get used to "touch" your eye. A thing you actually don't do as there is the contact between your finger and youur eyeball.
I have also used the lenses which are described somewhere above, which you can use for up to two weeks constnantly. While it is a really great feeling to wake up in the morning, not being blind, I wouldn't recommend to sleep with them if you don't have to.

For the second part of your question, which hasn't been answered here so far ( or I haven't seen it):
Yes there is a regulation in the U.K. concerning full face helmets. I just can't remember the correct jump number you need to have, before you are allowed to use one. I think, that it is 200 and its linked to having a ceratin FAI certificate level (either B or C).
You should be able to find sopmething about that in Section 6 of the BPA documents.

Thanks for answering that for me.

There are prescription goggles available which work great - the best of both worlds, in my opinion. A company called Sport RX advertises in the Skydiving mags.

barz optics also makes very nice goggles with presciption lensens/polaroid lenses/etc...
