¿Qué son las aberraciones ópticas? - Tus dudas de salud - aberraciones
I’ve got loupes, a handheld scope, and a scope for the camera in my phone, it honestly depends on the day and the plant which one gives you the best view. I guess I’m still hunting the right tool myself, lots of folks are chirping about the USB microscopes available on Amazon though, that’s one I don’t have that I’ll probably get to see if it works any better than what I already use
On almost any phone you can use your camera program and zoom in or out to get a good look at trichomes. Using 2 fingers touch the screen, spreading your fingers zooms in, closing them zooms out.
The coating is made up of carefully calibrated layers of metal oxides that are applied to the front and back of the lens and then irradiated with high-intensity ultraviolet (UV) light to enhance their light absorbency. This reduces reflected light and allows more non-reflected light to be transmitted through the lens.
This article discusses how anti-reflective coating works, the pros and cons of anti-glare glasses, and how much it costs.

Vision problems caused by prolonged computer use are common. A 2020 study published in the journal Cureus reported that computer vision syndrome—a condition characterized by headache, itchy eyes, and temporary vision changes—was higher in eyeglass wearers and those who reported glare on their computer screens.
It's worth asking your optician about other available AR coatings. Manufacturers are constantly updating their materials and may offer superior products specifically designed for night driving, sports, or computer use.

Yellow-tint glasses often touted to improve night driving vision, haven't been shown to be all that effective in clinical studies. Anti-reflective coating, on the other hand, does reduce glare and can improve nighttime driving performance.
I have a loupe and a 100x usb microscope but oddly enough my Galaxy S7 gives me a really good view to check the trichomes that I like better then the loupe or microscope.
Anti-glare glasses also may help people who are sensitive to light while driving in the daytime or those boating in bright daylight. AR coatings are available for sunglasses too.

Glare while driving at night is a common cause of accidents, especially for people with astigmatism. This eye disorder, which affects one in three Americans, can cause visual disturbances like halos and "whiteouts" with approaching headlights.
In the past, anti-reflective coatings were either painted onto the lens or applied to the lens like a sticker. But that's not the case anymore. Today, anti-reflective coatings are fused onto the lens matrix, a technology first employed with high-powered telescopes and microscopes.

Anti-reflective coating on eyeglasses costs more, but it may be beneficial in specific situations, such as night driving and preventing eye strain from computer use. On the other hand, the lenses are easily scratched and may require replacement.

That’s normally from touching the lense with sticky fingers, it seems blurry but it 's normally just dirty. Rubbing alcohol will clean it off
While it's not an outright necessity, anti-reflective coating is something you may want to consider if you have symptoms of eye strain or spend a lot of time in front of a computer.
Anti-reflective coating (also known as AR, no-glare, or glare-free coating) reduces glare by absorbing and redirecting reflected light. This allows more non-reflected light to pass through, leading to fewer visual disturbances. Unlike reflective lenses with mirror-like finishes, anti-reflective coatings are transparent with a very faint green or blue tint.

According to Vision Center, AR coating can add $20 to $150 to the cost of lenses. Insurance may cover some or all of that cost.

I have bought multiple jewelers loops and 100x zoom in hand held gadgets just wondering what everyone else uses and is a cheaper alternative ?
When you are checking the trichomes, it helps to take a sample and put it on a stable surface before you try and image it with the microscope. Sample stability is number one when taking a trichome photo. fantasmo-auto051792×1373 193 KB
Ya i bought multiple diff ones from Amazon seems to me the little hand held ones with led only work for little bit then hard to focus on them after a while and they are not really clear very blurry…

If you are considering anti-reflective coating, check the grading scale offered by your optician. Some opticians offer a choice of "good," "better," and "best" (or a similar scale) with the "best" grade costing considerably more.
The American Optometric Association lists eyeglass lens coatings as one of the more useful solutions for computer vision syndrome.
Even so, a higher-end coating can be well worth your money. In addition to the benefits, these lenses tend to have better warranties and may be replaced at no charge if your lenses are scratched within a year.
Anti-reflective coating on eyeglasses is designed to reduce glare, making nighttime driving easier, and reducing eye strain from computer use. The coating is fused into the surface of the lens, giving it a very faint blue or green tinge. Despite their benefits, anti-glare glasses tend to scratch easily and would then need to be replaced.

Thanks Oldjoints, I know about that. I just thought maybe he /she was using an app. I don’t find the magnification that clear on my S7 past a certain point. I’m pretty sure there is scope under the Xmas tree with my name on the box.
