How lenses protect your eyes?

The world is a beautiful place, but is that so without your eyes? Surely not. They say, “Beauty lies in the eyes of the beholder”, but what if the beholder lost their eyes?

It’s only when we look from a blind person’s perspective that we understand the actual value of having healthy eyes. Sadly, some people are born blind or with weak eyes, but for most, there are ways to maintain the quality of sight. To discuss this topic, firstly, let’s have a look at why it happens.

Why and when do the eyes weaken?
Oftentimes, older people have vision problems, and the situation is quite apparent. They might have macular degeneration, diabetic retinopathy, glaucoma, cataract, and/or various other issues.

But sometimes, especially in modern times, low vision issues are seen at a very young age. Technology has made our lives more comfortable, but on the other hand, it also has leveled up the setbacks as well. We might enjoy watching movies on our laptop or are stuck to games on a smartphone for long hours, but one thing we don’t notice often is it negatively impacts our eye health.

Moreover, UV rays coming out from the sun is another common reason behind the poor eye health these days.

But how do we tackle this? Well, read on to know.

What to exactly do to maintain the quality of your eyes?
Primarily, regular exercises and better nutrition are the ways to maintain the quality of one’s eyes. However, if that doesn’t work for someone, use of corrective lenses can.

How lenses protect our eyes?
Enhanced exposure of eyes to bright light and reflection makes it much more difficult to see outdoors. In that case, we need to make use of lenses to protect our eyes.

If one wants to understand how lenses protect our eyes, they first need to understand the basic functioning of our eyes. Our eyes include a retina that is a layer of cells that reacts to light. Whenever we watch anything, a reaction is performed, and the signals are sent to the brain, which further translates into the activities you are viewing.

These light rays ideally focus on the surface of the retina for perfectly visioned people, but when it finds any interruptions in between, the image starts altering-- It might shrink or blur somehow.

That’s where eyeglasses come in.

Eyeglass lenses are generally curved pieces of glass-like mermaid tears that work to bend light rays as they approach your eyes. These lenses only help the rays in focusing on your retina rather than behind or in front of it.

Based on where the rays fall, there are two types of lenses used to correct the position of the rays: convex and concave. In convex lenses, the curve is outward-facing, i.e., it’s for nearsighted people. In concave lenses, the curve is inwards-facing, i.e., it’s for farsighted individuals. That’s everything about the vision and lenses.

Wrap up:
Either concave, convex, on in some cases, bipolar, lenses help people maintain healthy vision. Of course, technology has given this to us, but healthy eating and exercise should still be one’s priority to maintain eye quality.

Try These 6 Healthy Activities This Summer


Summer is the perfect time to start getting into some healthier habits. The weather outside is nice, meaning you can do things outside that you don’t normally get to during other months. If you’re looking for some activities that you can do this Summer, and ones that will provide some health benefits, give some on the list below a shot. You may just find your new favorite activity.

Take a Hike

Hiking is a very healthy activity, and Summer is the perfect time for it. Hiking gives you a good cardio workout, exercises the leg and core muscles, and allows you to escape from everyday life for a little while. The best time to go hiking during the Summer is in the early hours, as it isn’t as hot then. Find some local hiking trails in your area, grab a bottle of water, and go explore. Once you’re out in the middle of nowhere, your mind will be more at ease, and your body will appreciate the tough workout.

Try Yoga

Yoga provides a lot of healthy benefits. It works out specific muscle groups, especially your core. It can also help to relieve stress, and make you more flexible (and therefore at a lower risk for injury). You can do yoga any time of year, but Summer allows you to do it outside. Doing yoga outside during some nice weather adds a great element to it, and can make your yoga experience even better. Find some yoga routines online that you like and bring your phone or tablet outside with you. Or, you may even be able to find some local outdoor yoga classes in your area that you can join.

Take Up Kayaking

If you want to spend some time on the water, kayaking is a great activity to try out. Kayaking provides a great workout to your upper body, and you get to spend a few hours out on the water with nothing to bother you. If you’re new to kayaking, you’ll want to avoid rougher waters, and instead opt for a lake or bay area. All you need to get started is a kayak (you can rent one or buy a used one), a paddle, and perhaps a life jacket if you’re not a strong swimmer. Then head on over to your nearest body of water and enjoy the ride.

Take Out a Paddle Board

Going for a ride on a paddle board is similar to kayaking. You give your upper body, including your core, a great workout. With paddle boarding, you stand up on a surf board, and use a paddle to navigate around. It may sound easy, but it will give you quite a workout by the time your done. Again you’ll want to do this in calm waters, as standing on your board will be pretty much impossible on rough waters. To get started do a Google search like “paddle board for sale near me”, then find a body of water near you that seems suitable.

Swim Laps

Swimming is one of the healthiest activities you can do. It works basically every muscle group while also giving you a cardio workout. And while you can swim during the Winter if you can find a local indoor pool, swimming during the Summer is much better. There’s nothing quite like jumping into some cool water on a hot day. You can go swimming either in your own pool if it’s large enough, or head over to a local lake. Either way, once you’re in, try doing these swim exercises to give yourself a good workout.

Read a Book

Finally, healthy habits aren’t all about physical health. Sometimes you need to take care of your mind too, and for that reading a book can go a long way. Set aside some time to sit outside in the nice Summer weather and read a book that you really enjoy. This will not only help you remove stress, but you may even learn something new. So, head on over to your local library, bookstore, or grab a Kindle, then sit down for a bit and relax.

Make Time for Healthy Choices

Even though it’s the Summer, our lives remain busy. It’s important that we set aside some time for healthy activities once in a while. The above activities are all great to do during the Summer, but they won’t happen if you don’t find the time. Pick one or two that you really want to try, set aside the time, and then go enjoy the Summer weather.

The 4 Greatest Security Risks for Healthcare Providers

Hospitals and health care facilities pose unique security risks due to the specialized nature of the services they provide. Any time an industry or organization does specialized work, it is likely to also require security defences that are suited to that kind of work.

That’s why it’s so important for those managing hospital security to understand the specific risks involved, in order to be able to assess the best security tools to put in place. For each of the risks listed here, it can also be shown that a security ID card printing system provides an excellent solution.

1) Theft

Whether it concerns supplies, equipment or personal data, all health care institutions must remain vigilant against stealing of any kind. One of the top targets of theft in hospitals are medications which patients often desperately require. Since hospital staff are already overtaxed with an enormous amount of work, they don’t have the extra time to be watchful for thieves. For this reason, hospitals can make easy targets.


Hospitals contain many areas that are off-limits to the public, but those places can be easy to access when staff are occupied elsewhere. That’s why a security ID security system is such a vital tool in a hospital. You can click here to learn more about this security solution, as well as accessories like badge holders and lanyards, contactless card readers and other technology designed to make passing through checkpoints quick and easy for anyone with the proper authorization.

2) Assault Upon Medical Staff


While it’s true that most of the violence inflicted upon staff in medical care facilities is caused by patients, this type of security rick can also be mitigated with the assistance of a security ID system. This threat increases greatly in the case of patients with psychological disorders, so psychiatric aides face the greatest dangers.

Security ID cards used in hospitals employ a digital technology in each card to make it easier for medical staff to access patient information securely. Using this type of system makes it easier for all medical employees to become aware of the risks involved with each patient, also with warning triggers, such as information about medications and side effects, as well as information about a patient’s psychological disposition and diet.

3) Child Abductions

Sadly, there is a history of infants being abducted directly from pediatric and maternity units, often with violence inflicted upon the mother. The best defence against this type of security rick is to prevent access to the areas.

4) Hospital Shootings


As in the case of public schools, active assailants in hospitals has become an increasingly escalating problem. Many of these incidents occur in operating rooms and emergency wards, which individuals with weapons should never be able to access under any circumstances.

Hospitals and health care institutions should operate with a proper security ID card system in place in order to ensure that hospital personnel are under surveillance and that no intruders of any kind are ever able to gain admittance. Contact a security ID printing solutions provider, to find out more about how to equip your facility with the best ID technology available, to ensure that it remains safe for patients and staff alike.

Does CBD Work? What Science Says About Cannabis?


It’s pretty much common practice for the American media to sensationalize and aggrandize basically anything that becomes of interest to the American population. It’s no different with CBD, which has become something like nature’s limitless drug, according to Americans. A lot gets lost in translation when the media exerts its influence over a topic, and articles are popping up all over the internet that sensationalizes CBD’s ability to cure cancer or instead, demonize it for being a complete “scam”.

Well, CBD is neither of these things; neither a wonder drug to cure all diseases, nor a marketing ploy to get Americans to empty their wallets. CBD is a real, viable cannabis derivative that is being seriously scrutinized for its application in a whole variety of different diseases. When used correctly and in the right context, it has the potential to target an array of symptoms that commonly afflict the American public.

The unfortunate reality with American economics is that as soon as investors see a financial opportunity, they jump on it, even if that thing is about the wellbeing of the country and its residents. Now, basically, everybody is a CBD product manufacturer trying to get a slice of the proverbial cannabis pie. This kind of attitude towards cannabis and its derivatives (CBD, THC, CBG, CBN, terpenes, and others) somewhat defames and devalues what these cannabinoids are all about. In any case, CBD is worth a proper mention and proper analysis rather than the hype that the media has been playing out recently.

What is CBD and What Does it Do?

CBD is a phytocannabinoid produced naturally by the cannabis plant. Unlike its cousin, THC, CBD is non-psychoactive and therefore doesn’t contribute to the euphoric (or for some, not so much) effects of cannabis. It is most commonly extracted from the hemp plant as hemp is naturally high in CBD levels, but from time to time, it is also extracted from marijuana.

In the context of medicine, CBD most often used as an isolated compound. Most CBD products are the result of some form of extraction technique. Essentially, these forms of extraction have led us to purer forms of CBD and, effectively, a more viable and acceptable form of medicine. In fact, the discovery and application of CBD in medicine has validated cannabis as a medicinal plant for the first time in over 100 years.

CBD and the Endocannabinoid System


The endocannabinoid system is something that permeates the bodies of every mammal on earth, including the human body. It a non-localized physiological system made up of endogenous cannabinoids (yes, we have our very own naturally produced cannabinoids) and cannabinoid receptors. It is, in its simplest form, a signaling system that modulates energy, metabolism, the endocrine system, mood, immune response, and the central nervous system.

Perhaps the most interesting aspect of the endocannabinoid system is that it is a signaling system that works in retrograde. This is unlike usual neurotransmitters, for example, which pass messages from the presynaptic neuron, through the synapse and over to the postsynaptic neuron. The endocannabinoid system affects the postsynaptic neuron, sending messages through the synapse to the presynaptic neuron. It acts as something like a dimmer switch, turning off electrical impulses or neuronal transmissions that have gone unregulated.

This is essentially why CBD is used as an anti-inflammatory, anti-epileptic, anti-nausea, anti-cancer and anti-anxiety drug. All of these symptoms are the product of neuronal excitement or overactivation of the immune system. CBD targets the system responsible for modulating these kinds of overexcitation.

CBD does not strongly interact with cannabinoid receptors, unlike THC. Its behavior within the endocannabinoid system is more peripheral, having more subtle effects. For example, CBD inhibits the behavior of a certain enzyme (FAAH) which is responsible for breaking down our own endogenous cannabinoid, anandamide. Elevated anandamide levels are connected with better mood, better sleep, and better appetite, and this is one hypothesized mechanism of action for the antidepressant effects of CBD.

CBD and Modern Science

 
What we are currently witnessing is an unprecedented amount of scientific research into virtually all cannabinoids, including CBD. In fact, CBD, along with THC, is the most studied and most well understood of the hundreds of compounds present in the cannabis plant. It would literally take forever to go through all of the scientific research about what this cannabinoid can and cannot treat, so we will exemplify a few.

CBD’s role in certain cases of epilepsy is perhaps the most pertinent of all cannabinoid research. It has been so thoroughly researched, in fact, that some physicians and medical professionals call it settled; there’s hard evidence at last.

There was the case of Charlotte and the strain, Charlotte’s Web, which was cultivated specifically for epilepsy treatment. And it worked. Charlotte subsequently experienced a drastic improvement in the number of seizures. Then there is the GW Pharmaceuticals study which explored the effect of Epidiolex, a pharmaceutical cannabinoid product, on those with Lennox-Gastaut syndrome. It is a rare and extremely severe form of childhood onset epilepsy. The results were overwhelmingly positive in the CBD group compared to the control group.

The next most important therapeutic aspect of CBD to investigate is its analgesic qualities. More and more Americans are switching to CBD as an alternative to opioids for the management of chronic pain. It has shown a lot of promise in the treatment of neuropathic pain, cancer pain and inflammatory pain. Researchers are still trying to understand the mechanism of action by which it exhibits analgesic properties, but there may be a number of things at play including immune response and desensitization of nociceptors.

Finally, there are countless studies which point towards CBD’s efficacy as an anti-inflammatory, antidepressant and anti-anxiety agent. It is even hypothesized that at the root of many treatment-resistant conditions, there is a clinical endocannabinoid deficiency that can be treated with both CBD and THC.

We Still Need More Research

So some of the media sensationalism around CBD is grounded but awfully presented. It is not a wonder drug any more than Aspirin is a wonder drug; it has a medical application that is targeted and effective if it is used in the right context. And still, science is still trying to understand exactly how cannabinoids work to have such a diverse range of effects.

Needless to say, we have spent the last 100 years prohibiting research on cannabis and we are now trying to catch up. We do need more research to better understand the best ways to use CBD and who benefits the most from this cannabis-derived compounds.
