Risks Associated With Online Eye Checkup

With the current world of new and advanced technology in all sectors of the society, new methods of dealing with problems are being designed and implemented. It is of special interest that in the medical sector, enhanced methods of eye checking have come up where patients can now check for their eye problems online with just a few clicks. It makes work much easier as a patient does not have to make visits to the optometrist every now and then to do a simple eye check up therefore proving to be convenient and boosting financial savings.

Opernative is one of the companies that provides online eye check ups and it strongly defends this telehealth stating that it is very safe. They explain that the procedure takes about 15 minutes or even less all depending on the nature of the eye problem. The patient is asked to explain what they see on the computer screen while standing 10 feet away. This is aided by the use of a smart phone as a remote control. After successful diagnosis, the patient is prescribed either glasses or contact lenses all depending on the nature of the illness or disease. However, this is only done after previous prescriptions have been analyzed and test results reviewed to check for any previous condition. The procedure only costs 40$ for the prescription of glasses or contact lenses and 60$ for both. This is very low and favorable to patients as compared to 127$ that will be charged when a patient gets physically tested by an optometrist.

On the other hand, this new telehealth has now gained much attention to lawmakers and other health practitioners. It has been stated that online eye check up may cause some health problems to a patient as it does not provide very accurate results. Personal appearance of a patient is necessary as other medical problems can be detected along the way when a check up is being conducted. This is in order to promote a patient’s health and provide proper diagnosis of infections. Pressure and the basic health of the eye is checked so that conditions that might have developed are detected as soon as possible so as to avoid future severe damages.

States in the U.S have regulated online eye check ups stating that they must meet consumer protection standards. It has been found that lenses that are not properly fit to a patient’s eye can cause serious damages that might permanently alter eyesight.

Clinical technologies like Opernative are seen as a threat to humans by optometrists and state officials and therefore they are not allowed to provide any low-cost services to patients. They are deemed to be inconvenient and unsafe. If telehealth becomes an adopted method of providing medical diagnosis and treatment, many patients will have illnesses undetected and this will worsen their health conditions thus making them more vulnerable to contraction of other diseases. Online tests provide refraction experiments to see if a patient is fit to put on glasses or contact lenses, but another condition can arise which will not be detected soon enough thus proving this treatment as dangerous and unsafe.

What Contact Lenses Should An Athlete Use?

Anderson SilvaDid you know that Anderson Silva, LeBron James, and other athletic idols wear LASIK, contact lenses, or glasses? There are many reasons that an athlete would wear lenses and glasses, a major one being necessity. To solve this need, athletes need to be keen when choosing contact lenses.

lebronWhen considering the ideal lens for a sportsperson, features such as replacement, handling, comfort, resistance to dust, safety, and durability come to the mind immediately. The truth is that no lens can accommodate all these requirements, so the challenge for a sportsperson is choosing the best lens for a particular sport.

Lens Options

There are many types of lenses that can improve the visual acuity of an athlete. Some of them are listed below:
1. Gas Permeable
2. Toric
3. Hybrid
4. Aspheric
5. Spherical

Contrast Sensitivity

contac lenses for sportsSome athletes may also look to correct their contrast sensitivity using contact lenses. A sport like baseball requires participants to see the ball against various backgrounds, for example dirt, grass, or the sky. To remedy such a problem, an athlete may use a higher modulus lens or a correcting cylinder.

Lens Movement and Debris Shield

baseballAthletes should not wear gas permeable contact lenses because factors such as debris prevention and lens movement are critical in a sporting activity. Athletes can use hybrid lenses and get the benefits of both soft lenses and gas permeable lenses. Hybrid lenses are comfortable and have quality vision.

Presbyopia Correction

soccerAthletes who suffer from presbyopia can choose from various lens options. If the condition is still early, the athlete can wear aspheric lenses. For more advanced cases of the condition, the athlete can consider several multifocal contact lenses including hybrid, concentric, and annular lenses. These lenses are available in gas permeable, hybrid and soft materials.

Athletes in competitive sports can do anything to excel in their disciplines. Flawless vision is a very critical factor in performance. Contact lenses can enhance the vision of athletes by correcting common visual conditions. Choosing lenses that are both comfortable and functional will yield success in the field.

Implications Of Not Wearing Prescription Glasses

shortsigtednessPrescription glasses are specially designed to help you see better. And that being said, you should always wear your glasses while doing important tasks such as, reading, driving, working etc. However, many people with shortsightedness avoid wearing their prescription glasses. Despite the reasoning behind that, not wearing the glasses when you need them, can have serious serious effects in the long term. Here are some of the implications of not wearing your glasses:

Worsens Vision Over Time

Glasses simply help to improve vision, and if you do not wear them, it may cause your vision to grow worse. Long term effects may include incomplete development of your eyes. Getting a very clear image to your retina helps your eyes to grow properly, so when eyesight isn’t very clear, it keeps your eyes from growing as they should be.

Contributes To Eye Strain

This is one of the major side effects of not wearing prescription glasses. It may contribute to fatigue, headaches and eye strain. Although this does not damage your vision permanently, yet it can be extremely uncomfortable. Also spending several hours in front of the television, or working in poor light without wearing glasses can tire your eyes.

Develops Lazy Eye

In case of near-sightedness difficulty seeing far away, the eyes are too strong and they just focus on objects that are very close. It is extremely imperative to wear prescription glasses for this vision to avoid developing lazy eyes, which can easily occur if you do not wear corrective glasses.

Causes Eye Pain

In case of far-sightedness- difficulty seeing very close, the eyes have to work extremely hard to focus on objects which are near, and if you do not wear glasses, it may result in eye pain, fatigue and other long term effects.

So it is extremely indispensable to wear your prescription glasses to keep your eyes strong, healthy and in a good working condition.

But wait, have you planned your strategy of purchasing sunglasses well? Have you done your research for reliable sunglasses sellers, promotions or discount coupons? If not, this article will help you now.

After reading the points given below for selection of sunglasses, you will stop taking this extensive eye accessory just as a fashion-ware. So check out the points mentioned here that should be taken under consideration earlier than investing your money on expensive sunglasses.

Vision and comfort

try zenni opticsComfort comes at the foremost position when it comes upon shopping of eye-wears. Whether you are going to buy sunglasses for an adventure trip or you want something different and latest to add in your fashion wardrobe, comfortable approach comes at the top always. No matter, what brand, what design and what frame you choose in sunglasses, you should try them by wearing in the store for about half an hour to be assured about good vision and comfort.

Always choose light and well fitted frames as heavy frames can cause headache when you wear them for long time. This point should be kept on mind more when you are choosing a frame for regular eye-ware. Titanium frames can be a good choice for the reason they are non-corrosive, durable, flexible and light weight. Also these frames are hypoallergenic offering a longer lifespan to those who want to use the glasses regularly.

Material and lenses

polarized-lensThe material of sunglasses should also be selected wisely while shopping of these products. Many people love to purchase polarized lenses but if you are doing so by thinking that those lenses help in UV protection, you are wrong. These lenses work by absorption of light waves that causes reduction of glare. In this way, these lenses offer clear vision but not UV protection. On the other hand, tinted lenses offer special benefits according to their tint shade. For instance, grey lenses reduce darkness without distorting colors. Similarly, green lenses reduce glare and helps in better contrast between objects.

Some people think that darker the lenses, more the sunglasses protect will protect eyes. Actually, this is a myth; it is important to know that tint or shade of the lens has no relation with the intensity of UV protection. Regular eyeglasses that have been designed specially to protect eyes can offer better results than a darker pair of eyeglasses. High quality materials, apart from the brand, can raise the price pretty high. That’s why you should search online for promotional offers e.g. a zenni optics coupon and have a discount on your order. So, keep this thing on mind next time when you go for shopping of sunglasses.

Shape, size and shade

Here is what comes over the appearance. Whenever you choose an eye-ware, it is important to determine particular shape and size of the same to suit on your face. A wide variety of shapes and frame size is available in market today such as oval, round, angular frames, curved frames and so on out of which you can choose a design that looks beautiful on your face. You can also get advice from professionals to determine that what shape and size of eyeglasses will look good on you.

zenni optics sunglassesNext comes upon the shade. Here again it’s up to you that what shade you choose but always remember that shade of the product not only decides it’s color but also offer you particular benefits. For example, yellow colored glasses offer sharpness to images but causes distortion of colors too. Rose lenses are good choice for those who are shopping for water sports and outdoor activities.

Protection

As it has been discussed above that the shade of your sunglasses never ensures more protection against UV light. This is why, you should always check whether the product you are going to purchase offers extensive protection to your eyes or not. Protection cannot be ever compromised when it comes upon eyes because lack of UV security can cause dilation of pupils, more exposure of iris to UV rays. You can even get your eye-wares tested at the office of ophthalmologist to clear your doubts.

So, you know well about the important points you should take care while shopping of sunglasses. These are some basic but effective things that will help you to choose the best suitable product. Also, you should understand now that a good and durable product needs not to be invested lots of your money on it. You can get the best eye-ware even within a reasonable range under your budget.

Anti-Reflective Coating on Eyeglasses – See the World Clearer and Better

Basically, anti-reflective coating works to reduce reflection or eliminate glare by applying it on the surface of lenses and other optical objects. It allows more light to pass through the lenses to give a much clearer and more enhanced vision possible.

How are We Able to See Objects?

When looking at an object, what is perceived by our eyes is the light that is reflected by the object itself. That is the reason why it is not possible for us to see things in the absence of light. As the light enters the eye, it goes through the cornea and hits a specific spot at the back of your eye, which is the retina. If you are having problems with your vision and need glasses to see clearly, it is because the light is not exactly hitting the retina of your eyes, either your eye may be too short (hyperopia) or too long (myopia), or your cornea is not in the correct form (astigmatism).

Anti-Reflective Coating on Corrective Lenses and Its Benefits

Anti-Reflective Coating on Corrective LensesAnti-reflective coatings are widely used in different applications like on camera lens, solar lens, telescopes, and corrective lenses. More often than not, optometrists prescribe “anti-reflective lenses” to their patients for the reduced reflection makes them look better. These lenses decrease glare, but the reduction is very minimal. However, since it allows slight more light to go through, a considerable increase in visual acuity and contrast is produced. The lenses will look nearly invisible too, which draws more attention to your eyes and helps you have a better eye-contact with others.

Other benefits of this type of lenses include a sharper vision with less glare, especially when you are driving at night. They also provide greater comfort when you are using a computer for a long time. It is to be noted though, to avoid confusion, that when we say anti-reflective, it refers to the reflection coming from the surface of the lens itself. It is not the source of the light that reached the lens. There are many varieties of anti-reflection lenses these days that have additional coating, which make them water or grease resistant. This also makes the lenses much easier to clean.

How the Coating is Applied?

coating lensesA highly technical procedure is needed in order to apply anti-reflective coating to lenses. It actually involves vacuum deposition technology. A productions line is usually a series of washing and rinsing baths, which includes ultrasonic cleaning to eliminate any traces of contaminants on the surface. Air drying and heating of the lenses follow to remove moisture and gases. It is then placed inside the coating chamber that is sealed and air pumped out to create vacuum. Then, the coating materials are bombarded with electrons to create a uniform and ultra thin optical layer on the lens.

 

How To Tell If Your Sunglasses are UV Protected?

Sunglasses are UV ProtectedSunlight is the primary source of UV light. Too much exposure to UV results in various long-term eye issues. People usually buy sunglasses as a preventive measure to these problems. As much as they may labeled to provide UV protection, most sunglasses do not. For the sunglasses that have reliable safety ratings, their UV protection wears off with time.

How can people tell if their sunglasses are 100% UV protected? This is a question that has troubled many minds. There exists no independent verification of the UV protection claims made by various brands. It is important to note that a higher price provides no guarantee of UV protection. I have tested numerous expensive sunglasses that have claimed to offer 100% UV protection only to bear witness to their shameless deception to the public. Surprisingly enough, I found some relatively cheap glasses, ranging from $8 to $25 offering effective UV protection.

UV flashlightTesting can be one with a simple trick that will require access to a UV flashlight. You can find an affordable UV flashlight online or borrow one. Once you have it, go with it into a darkroom together with the sunglasses and paper money or a credit card. Turn on the flashlight and beam it on the credit card or money. Various strange symbols that you do not usually see in ordinary light will become visible. They include a line on the paper money and letters on credit cards. These are watermarks that the government and banks use to identify counterfeits.

After confirming the appearance of the strange symbols, you can proceed with the testing of your sunglasses. Beam the UV light through one of the lenses and onto the credit card or money. If the symbols are still visible, your glasses are not 100% UV protected. This means the lens is letting the UV light through and as a result, the symbols become noticeable. However, if you cannot see the symbols, the sunglasses offer 100% UV protection. The lens is blocking the UV; hence, the symbols are no longer visible.

Sadly there is little regulation of sunglasses as labelling can be deceptive. Over the years, this test has led me to discover that many expensive sunglasses which are said to provide 100% UV protection do not. I would advise all buyers, if possible, to test their sunglasses at the store. If you have already bought them, return them immediately for a refund.

opticianIn order to order your eyeglasses online, you must have your most recent prescription. Should you find yourself without a prescription, or you have not had a new exam in quite a while, you will need to schedule an appointment post haste. As a general rule of thumb, an eye exam needs to be had every two years, if you have exceeded this time frame, schedule an appointment today.

A scheduled optical exam will not only provide you with a prescription for your impending purchase, but your general eye health will be verified. There are a variety of health problems that are able to be detected through an exam conducted via an optician.

Here is a simple guide showing how to read your prescription:

Get Your Prescription

You will need to keep in mind that it is illegal for a physician to deny you access to any portion of your medical records. There are opticians that will attempt to intimidate you out of leaving their office with your prescription in hand. This is only due to them wanting to secure the maximum amount of funds from you. They are truly fearful that you will purchase your eyewear elsewhere. You have just had your eyes tested but your optician won’t give you a copy of your prescription for the fear of you not buying glasses from them?

Why Should you Choose Thin Lenses?

thin or fat lensesAlthough standard lenses are perfectly suitable for low prescriptions, they can become quite bulky and uncomfortable the greater a prescription is. For those that have higher prescriptions, it is widely recommended that thin lenses be chosen as you place your order. High index/thin lens options offer consumers a reduction of weight on the bridge of their nose as well as behind the ears. Afford yourself with a much more comfortable and attractive option while concealing the depths of your optical challenges in details.

Understanding Available Lens Coating

The vast majority of online retailers are able to offer you with anti-reflection, scratch resistance and VV protection coated lenses.

Contact Lenses: Hard Or Soft

myopiaMore than 225 million Americans (75% of the US population) use some kind of visual aid – glasses or contact lenses. From them, around 30 million  wear contact lenses – out of which 65% are women. In some cases, these individuals have found that prescription glasses can be somewhat of a nuisance to keep up with and found contacts to be much more convenient. Theses lenses are available in various forms – namely soft or hard. Its important that you know a little background on both so that you can decide which is best for you.

The Background Of Contacts

As surprising as it may be, the idea of contact lenses was first cultivated by Leonardo Di Vinci in the 1500s, however, they were not officially developed until 1970. Researchers were able to create visual aids that were both practical and affordable. GP lenses, also known as rigid gas-permeable lenses and soft lenses are the most common forms of lenses today.

Hard Lenses

hard vs sof tHard lenses were originally composed of glass. As time progressed, researchers developed a plastic that would be less likely to shatter. Though this plastic, known as PMMA, was less fragile than glass, they were difficult to wear because they didn’t allow for proper air flow. Today’s hard contacts, rigid gas-permeable lenses, are made up of silicon which not only makes them more flexible but also allows the eye to breathe.

Soft Lenses

Soft contacts are considered to be the most popular lenses. Many consider them to be more comfortable than rigid lenses because they have the ability to absorb more water. For new contact wearers, soft lenses also offer a quicker adjustment period than hard ones. These lenses offer a variety of different colors.

Which Is Best For You?

lensesBoth types offer several benefits. Hard contacts are unique in that they can be customized in order to fit the individual. Technician can consider the specific shape of your corneas as well as your eye curvatures. Both of these factors will help to make your vision much more crisp in comparison to the soft lenses. However, one must also consider the downside to wearing hard lenses. There are several wearers note that in order to feel comfortable, they must be broken in and this adjustment may take a while. Also, if you were to go back to wearing your glasses and then switch back to your hard contacts, your eyes will have to readjust to them once again.

Soft contacts have their pros and cons also. They are considered much easier to adapt to. This is due to the fact that they can hold up to 80% more moisture than the hard lenses. Another advantage is that soft lenses make it easier for the user to switch back and forth between contacts and prescription glasses. However, one must also consider they fact that soft lenses are disposable which means they may be more costly due to the constant investment they require. Though some consider their disposable nature to mean there is less maintenance involved.

The Verdict

Both the hard and soft lenses serve to correct astigmatisms. If you would like to invest in lenses that offer sharper vision and okay with the idea of a long adjustment period, then you should consider buying hard lenses. However, if you are more interested in comfort and don’t mind investing in disposable lenses, then you should consider soft contacts.
