poor vision due to rain and condensation on glasses

Does anyone have any good ways for making prescription glasses water repellant?

I looked through some older discussions and the only two methods that I could find were Rain-X, or eye laser surgery!   I'm not going for the surgery just yet and I need to wear the glasses during the day for work.

thanks

Had this problem for a long while. Found a solution that works for me. I just stop & squirt all lens surfaces with water from my drink bottle now & then, shake off surplus (don't wipe), & problem fixed!

To stop fogging of skindiving mask, rinse inside with detergent or, more commonly saliva. Then rinse in (sea) water.

When you get to my age youre eye brows start getting very bushy...perfect for soaking up the water before it gets to the glasses. John Howard would never have problems with his glasses fogging up.

Contact lenses and cycling sunglasses

On glass glasses, you could try Dri-Wash waterless car wash spray.  makes the water bead and run off.  Don't know whether it would adversely interact with plastic lenses, though.

I wear glasses as well.

I don't know any answers the the question.

However I would be cautious about putting chemicals on the glasses and then near your eyes.

Does your local optometrist have any suggestions?

Anybody considering contact lenses should do some research on amoebic keratitis.

That said I have an uncle who has been wearing contact lenses for 40+ years because his vision cant be corrected with glasses.

When I was a young boy working on the mines in Broken Hill many decades ago they supplied Egg Creme Baby Shampoo for use on safety glasses underground. You wiped it on the lenses and this stopped condensation and fogging up.

Ride faster ;-)

Above about 40kph the wind clears away most of the rain drops for you. So you may start a descent totally blind, but about half way down you can see what you've got yourself into.

the condensation on the glasses is (probably) due to body heat being trapped behind them. My Oakley glasses have vents to allow cooler air in and the warm air out.  How do you feel about drilling holes in your prescription lenses? ;)

you could try this:

Condensation - no answer.

Sweat - no answer (yes, I have this problem all rear round)

Drizzle - snarl and live with it.

Rain, as in the steady stuff, I've had good results simply by leaving the visor on my helmet. I discovered that by tilting my head down and looking through the slots in the visor, less rain gets on my glasses and I get much better vision than letting all that damned wet stuff get all over my glasses. YMMV and having now suggested it, it probably won't work for me next time.

Taking my glasses off isn't an option as I can only see about two feet clearly without them and it just keeps getting worse from there. Sure, I can't see with glasses covered in road spray either, but it's better and the occasional swipe with a gloved finger is satisfying (if not overly efficient).

By far the most efficient option is to say 'fuggit' and take the MG (even with the lousy demister and worse wipers)

the down side of the synthetic materials is that they are useless for wiping dry your lenses, even if you find that dry patch of jersey at your lower back!

glasses on - no viz.  glasses off ditto.

@ snappy don, have you noticed that the faster you go in the rain the more wet you get? so whilst the movement wind blows off the old rain drops, you are actually collecting new ones even faster. Perhaps I could modify a CO2 cannister tap to blow them dry...

or try this:

I use a spray called Plexus on motorcycle visors (and bike bodywork), It was developed for aircraft windscreens and masks fine scratches. It is silicon based I believe. Water beads off the visor very nicely, you could clear the outside of rain with a twist of the head.  As for fog inside I reckon ventilation is the key for me.
