Contact lens vs Glasses?

[Guest]

And here I use my usual dish-washing soap to clean my glasses (as recommended by my optician) and quite incredible it works fine and even better than the "special tissues for cleaning glasses" sold in shops.

 

Life is sometimes so easy/simple when you don't want to make it more complicated than it needs to be

I use both these days. 

When I was a teenager I used only glasses because they were affordable only needing to buy 1 set, and they were just easy maintenance. 

When I got older and started going out to night clubs and stuff then I switched to contacts because glasses were annoying. 

Now I typically use glasses during the week when im working, especially since I work in aircon which tends to dry out my eyes with contacts.

I'll typically wear contacts for the weekend especially in summer so that I can wear any sunglasses when im out that don't have to be prescription.  

I also find contacts less annoying when im doing a heavy gaming session. The'yre generally clearer as well since I cant smudge them or get  dust/hair/etc..all over them like I do on the lenses of my glasses over time. 

 

My prescription is -2.25. 

I typically use the Acuvue Oasys, I find them really good for being able to just wear a pair right through the weekend. The box of 6 typically lasts me a couple of months depending. I give them a good clean and store them in solution between weekends so a pair often lasts me a good 2 weekends or more.

Biggest pain in the rear for the glasses though is rain.

I actually like glasses in the rain, keeps rain from going into my eyes.

My glasses are ten years old by this point (so whatever coatings applied have long worn away), so I wonder if some Rain-X would do just as well?

I am in no way an expert on glasses, but you could try. I've heard that rain-x wears away quickly though.

You know they invented this thing called Umbrellas and hats right?

I was stating costs for regular spherical ones. If you have for Astigmatism or Multifocal, they will be more expensive as they have per user parameters and are pretty much made on order.

 

Acuvue lenses were known to pretty much disintegrate with usage, often way before it was replacement time. Hard to say if they improved their materials in current times. Same can and does apply to other brands where lens can degrade over time. It's just a matter of how much. Comfort is also dictated by cleaning solution. Peroxide ones seem to do the best job since they are the most aggressive and oxygen bubbles seem to rub them during disinfection process which makes them cleaner without any physical rubbing from the user. It's too bad Alcon screwed up their AOSept solution by adding Hydraglide lubricant to it, which causes foggy vision pretty much instantly. B+L's EasySept seems to be one of rare pure peroxide solutions left, but it's super hard to find which is annoying. And with peroxide solutions, you use them up faster coz the lens case is a lot bigger and you need to pour more of it in.

 

Which lenses and solution are you using?

(approx. €50 for 6 for my left eye and approx. €80 for 6 for my right eye

The lenses for right eye have astigmatism and those for my left eye do not.  My left lenses are -0.75, and the right are +0.75 and -0.75*180. No, that was not a typo. I have mark'ennovy Xtensa lenses for both eyes. As for the solution, Oté Sensation (Multipurpose Solution with Hyaluronate). Composition: PHMB, Polyquaternium, Hyaluronate.

 

Funny thing is that the first site that explained what astigmatism is (I'm used to all words being in Dutch, and in Dutch we often use "cylinder" when describing astigmatism) was from Acuvue.

@TomvanWijnen

Well, Xtensa lenses are hydrogel based which means they have a Dk/t of around 30. So, there's your problem with comfort. They have silicone-hydrogel based ones, but they only have 60 Dk (not even Dk/t which also takes lens thickness into consideration). It's a lot better, but still pretty bad compared to Biofinity (which is highly regarded brand for astigmatism lenses) with Dk/t of 160...

Hmm, interesting, thanks! I was going to go to my optician soon anyways (just 1.5 months of lenses left) so I'll ask them about this.  Do you recommend the Coopervision Biofinity? The regular version has a Dk/t of 160, but the toric version has a Dk/t of 116, according to this site: https://www.visiondirect.nl/biofinity-toric. Other sites either said nothing at all, of 116, and one said 128. Huh?

Coopervision (the manufacturer) says it's Dk/t of 128 for Toric lenses. Still a very high number.

Do you recommend those, or others? Much better than 30 though indeed lol

I can't comment on toric lenses specifically since I'm not wearing them, but I've had great experience with Biofinity lenses. I guess with toric lenses it depends on the wearer and technology used to keep toric lens where it has to be. It's unfortunately impossible to know until you try. Ask your ophthalmologist if he can supply you with test version of Biofinity Toric so you can see if they work for you. If not possible, it's worth risking and just trying them. I did so with quite a lot lenses and now I know what works for me and what doesn't.

Cool, thanks! I'll go there soon and ask for a test version - that was possible with these lenses too, so hopefully with those as well.

Add me to team contact lenses but not through choice. I've got a condition called Keratoconus which means the lenses in my eyes are mishaped. Basically the light hitting my lenses doesn't refract properly and it makes my vision VERY blurred.

 

I have to wear contact lenses as the corrective lens has to touch my faulty lens in order to correct it's shape.

 

The easiest way to explain it is this, imagine you have a picture that's blurry and you take a magnifying glass to the picture, all you would do is magnify the blur, right? You have to fix the blur before you can magnify it.

 

I have RGP lenses, they took some getting used to but these days in can wear them for 16 hours without to much fuss. Heck I've gone 24 hours with them in in the past.

@Master Disaster

I'm pretty sure contact lenses can't touch your eye lens Eye's lens is located under cornea. Keratoconus is a misshaped (usually as a cone) cornea which causes light to enter the eye and the lens at wrong angles, creating multiples of image you see (if you look at one light you'll see many of them around). Where in case of most lens users, contacts are in fact correcting the distortions of the lens (or the retina). Where in your case, it's correcting the shape of cornea.

Hey, I'm not an optician

 

Also can confirm the multiple images, and halos around lights, and blurryness. It sucks.
