Photochromic lenses already block blue light, no need to add a specific filter for that. It would even make the photochromic lenses work less good when added.

Nah.

UV blocking 100% worth it.

Blue light is debatable, as most devices have a blue light filter in the system settings are can be applied with third party software.

I personally have generic photochromic lenses on my glasses, and they add more of a tint compared to sunglasses. I also have polarized Transition lenses on another pair which are pretty convenient if not driving. (Use a dedicated polarized sunglasses for driving)

None of these should negatively affect the integrity or longevity. Transitions XtraActive polarized lenses have a slight tint to them, but generic or non polarized photochromic are basically clear.

Also, generic photochromic lenses are like $9 at Zenni, compared to the $100+ for the Transitions brand.

Photochromic: people either love it or hate it. I'm not a fan.

Blue light: not worth it

UV Blocking: 100% worth it

I have purchased lenskart glasses. BLU Screen Lenses+ Blu Photochromatic. Here's the price breakup: Bluecut Fully Loaded anti glare thin lens ESS- inr 1200. Blu Photochromatic- inr 3500. It's been almost 5 days since the purchase and the glasses do not change the colour under the sun. Once, the glasses turned a very mild, almost unnoticeable shade of black but that's it. The total cost of the glasses were 7k. Anybody has any recommendations on uv blocking and Photochromatic glasses? Should I return these glasses?

i have the polarized Xtractive . they come with all the uv-bluelight blocking. Which is a must for a person like me starring at a computer 15 hours a day. But great when you go outside or when you are driving.

Another commenter said theres did not get very dark in the car while driving. While mine do not get full on dark like when outside I would say 60 percent at least shade and never had issues driving. Maybe the extra polarized helps (not sure if theres was)

If you are willing to spend the extra cash on it - it is very well worth it. Even with insurance paying i think my bill for the pair of oakelsy i have with high index lenses cost me around 450-500. With insurance paying for around 250.

Photochromic 100% worth it :) they also give you blue light protection - it’s debatable but I just like that slight yellowish tint. If you choose photochromic don’t go for the cheap ones, go for Rodenstock Colormatic, Zeiss PhotoFusion or Transitions

Photochromic lenses are great if you're sensitive to light because they "self-adjust" based on how much sun is out, so you're not struggling to see through the darkness on cloudy days like you would with regular sunglasses. But if you need strong sun protection, especially in the car (where photochromic lenses don't work well), a pair of prescription sunglasses is better. Every lens type has pros and cons, so it really depends on your needs

Just go to a reputable place that offers a replacement policy if you don’t like them. Odds are you won’t get the money back but you can get new lenses made without them if you hate them

I personally hated them. I never liked the tiny tint indoors and the time to return to “clear” always was too long. But I sold them because some people are not both bothered by that or the benefits out way the negatives

Transitions xtraactive and polarized take care of 2/3 issues, working in cars and being more temperature stable. They have a 10% tint, but it’s not too visible when you’re looking at them. I’d definitely recommend, I don’t notice much difference when wearing, except more relaxed eyes.

They do work in cars, but they’ll work BETTER if you get them fully dark, then get in the car, rather than the slow activation through a UV shielding glass.

LDO here! Love the new gen s transitions. Transitions are wonderful if you are in and out a lot throughout the day or light sensitive. They have a transition, transition extra active, and a transition polarized. Each level gets a little darker and the extra active will have a slight tint on it all the time. Personally I prefer the regular transition because I don't want the tint on my glasses all the time but love having it until I switch into my sunglasses.

Some folks love, others hate. Unless you get the Xtra active, they do not darken in a car. Tend to get darker in cold weather than in hot. Take about five minutes to fully lighten indoors. For me this is a deal breaker. I don’t like waiting for them to lighten.

Yes, if light changes during your ride. I mostly ride gravel and there is a huge difference between open road and a dense forest, they are awesome for that.

Yes they're fantastic to use, I ride in direct sun, cloudy, and at early morning/night with the same glasses.

This also my primary use case. I commute morning and then again in the evening and want to only need one pair of glasses if it is dark, cloudy, or sunny.

Dang, what brands do you recommend? And is it worth it to pay double for prescription lenses?

They’re great. Pro tip though, don’t wear them in the car. The windshield blocks the UV rays so they don’t work.

I have photochromic prescription Oakleys and they are fantastic for riding around sunrise/sunset.

But I only have them because I need prescription lenses. If I could have normal glasses I wouldn’t bother with photochromic. They’re more expensive, only come in limited colours/coatings and most importantly they don’t block as much light as dedicated lenses do.

All of my glasses are photochromic, it’s the best invention for a person that has to wear prescription glasses and can’t/don’t want to wear contact lenses. I HATED to always carry two pair of glasses everywhere, no more need to. Also, it’s cheaper since instead of having to buy one sun prescription glasses and another regular one, I only need to buy one. That shit’s amazing.

I'm in the same boat. I need prescription lenses and the vast majority of my rides are near dusk and dawn. I used to have to carry 2 sets of glasses.

My motorcycle helmet has a photochromic visor, unfortunately it doesn't come with a pin-lock (reduces fog) because of this, but otherwise it's pretty nice

Was my go to brand before I needed corrective lenses. Could usually walk into REI and walk out with their lightest version (cause I’ve lost a pair or two over the years) so riding before sunup without tint worked very well.

I have two pair. Unfortunately they are worn out and don't darken much anymore. I didn't know that would happen.

Frame color is fashion, lens color is function. How sensitive are your eyes? Have you had photochromic lenses before? Photochromics are light adaptive and heavily rely on UV activation, meaning even when it’s bright out if you’re behind a UV protective surface (many residential windows and automotive glass have some degree of UV resistance) the lenses won’t darken to their full potential.

Standard colors are grey and brown. Grey/smoke is a neutral tone and has the darkest color; it won’t distort colors, just makes your view darker. Brown is lighter than grey and provides more contrast, which is useful for overcast days. If we consider brown similar to amber or orange, which is yellow + red, the yellow provides contrast and red can help with depth perception. Extra Grey is a popular option now too, getting darker than Grey but oftentimes the manufacturer disclaimer will tell you they’re not expected to fully lighten back to clear so you might have a residual tint when they’re not activated. This option is great if your eyes are very light sensitive or you spend a lot of time outdoors. Standard colors will typically turn clear more quickly though, so if you’re usually in and out pretty frequently you may want a standard option. I sell ZEISS lenses and we also have an option called Pioneer Green. It’s a grey-green and I wear it myself. I like the darkness of the grey and the way the yellow component of green brightens my vision. Think of the color of old RayBan aviators’ lenses; they don’t appear overly green. Transitions has jewel tones such as Emerald (green), Amethyst (purple), Sapphire (blue), Amber (orange), and Ruby (red). If you’re looking for a dark option, consider the Emerald or Amethyst. I’m not sure if Transitions has any disclaimers about Sapphire, but Zeiss has a blue lens option and indicates it is not for driving as your vision can be impaired when viewing traffic lights. Amber is a brighter option to brown. Ruby is new to their portfolio and is pretty, but doesn’t look dark.

I recommend asking your optician for a demonstration before final selection. There are online demo tools, but many shops have samples you can see both clear and activated, and even look through while darkened to make sure you like how your vision will look when worn. You’ll also be able to make sure you like the frame/lens color pairing.

With a neutral frame pattern like this one, there is no wrong choice. Update when you get your new lenses so we can see the finished product!

I use photochromic prescription glasses for backpacking.. Some people may want a darker lens for sunny, high altitude trips, and/or polarized. But for me the photochromic is fine even though they don't get as dark as my other sunglasses. At night they are totally clear as far as I can tell.

I used to, I had no issue with low light with my old transitions, but they never got dark as I needed, I'd go out to the desert and still end up with red sunburnt eyes.

They've probably gotten better since then, but a pair of polarized aviators is still my preference.

I like Julbo’s lenses. I have two pairs of their 0-3: the Density and the Renegade.

I also have some Tifosi Moabs with their 64/14 lens (they don’t do categories for some reason). I like the frame better than the Julbos because of the adjustability and the lens is fine for most situations, but I do notice the Julbo lenses are clearer. I also notice that the Tifosi lenses tend to darken in chunks.

I’ve ridden with both brands at night and the light transmission is sufficient to not over-ride my lights at 20mph.

Something to consider - if you wear a hat to shade your face, the lenses won’t be exposed to as much sunlight and won’t darken as much as they would if directly exposed to the same light conditions.

I’m sorry to say, but 250-300€ will not even get you close to what you are looking for. Serengeti starts at over 300€ for their non-prescription sunglasses, with correction will cost 650-950€.

The best photochromic prescription sunlenses on the market right now are Zeiss AdaptiveSun (Polarized is available). A pair of those will cost you already more than €300 (and you’d still need a frame to place them in).

You are looking for transitions drivewear. Get darker in a car, go from light green to dark brown, and are polarized.

Maui Jim makes some of the best lenses available, but they don't do their best work in prescription.  Serengeti does, and theirs are photochromic.  Both companies make fully protective sunglasses that are a joy to see through. 

Most photochromic sunglasses work by reacting to UV light.  And your windshield blocks it.  I don't know if all the windows in a car do, or about the sunroof.  But since they're not getting a lot of UV, they're not going to darken much until you get out of the car. 

I do a lot of cycling starting pre dawn. They are great for that. Otherwise I prefer the standard lenses.

I have a pair of Tifosi brand glasses with chromatic lenses. They work really well. I’ve been freed from having to bring clear lenses and the faff of lense changes to suit the conditions.

I didn’t like them at all when riding in the mountains where there are a lot of light intensity changes, they always seemed to respond too slow.

I bought Tifosi's Sledge Light glasses on a whim and really like them a lot. They're basically always the same shade of darkness and I never feel like its too bright. Only problem I've noticed is from time to time they bend the light in a weird way so you will see small reflections from headlights / taillights under certain lighting conditions but it's really no big deal.

I have been wearing a pair of Tifosi photo chromatic glasses for years. They’re great for changing conditions, cloudy wet days, mountain biking in the woods, riding tree lined roads with heavy shadows, etc. If I were riding somewhere with a lot of sun and little tree cover I might want something that got a little darker, but for where I live I find I don’t need really dark lenses for riding.
