contact lensesWhich Contact Lenses are the Best?
Millions of new contact wearers wants to know, “How to find the best contact lenses? The best contact lenses are the ones, the doctor prescribes, the ones that improves visibility, and the ones that easy to put in and remove. Wearing contact lenses can be fun, and exciting, especially for first time contact wearers. However, safety should be a priority. Let the optometrist write a prescription that is best for correcting and protecting the eyes, from the harsh environment. The right lenses will protect the eyes from becoming sore, dry, and watery.
Choose Contact Lenses that Compliment and Protect the Eyes

Contact lenses provide an alternative to eyeglasses. Unlike eyeglasses, contact lenses fits inside the eyelids. They are comfortable, lightweight, and eye to use. Optometrists prescribe contact lenses for vision correction, in place of eyeglasses, or in addition to eyeglasses.
Optical wear technology has changed dramatically, and contact lens has come a long way. Today contact lens wears are not bound by one or several styles of lenses to choose from, In fact, they have dozens of styles in which to choose. Contact wearers’ options ranges from specific designs such as sports, work environment or everyday use.
As it stands, nearly 40 million people wear contact lenses in the world today. While some people wear decorative non- prescription lenses, other people wear prescription drugs. Wearing contacts begins with a visit to the optometrist. The optometrist will determine which prescription contact
Outdoor Activities
Bacteria can easily containment lenses, getting behind the eyes and causing them to swell, or become red and irritated. This usually happens with swimming. Soft contact lenses are designed for one time use only, and as soon as the swimming session is over, the lenses should be removed from the eyes, and disposed of immediately.
Outdoor Environmental Use
Working outdoors in the harsh environment can cause damage to the eyes, regardless of the temperature or climate condition. The best lenses to choose are the ones that provide enough moisture to keep the eyes from drying out. These are lenses that are ridged, and contain a high oxygen content. Also wearing tinted lenses in the daylight can help with visibility during the daylight hours.
Suffering from dry eyes is no joke, and wearing ridged contact lenses can make the eyes worse. Wearing soft plush lenses with low water concentration works best for dry eyes. Some materials used to make lenses actually pulls the moisture from the eyes, and puts them into the lens.
Contact Wear
Ridged contacts are better for constant every day wear. Wearing contacts for the first time, may seem a bit weird at first, but these types of lenses are actually better for the eyes, over an extended period of time. Despite of what people might think, contact lenses are not one size fits all, except the cosmetic ones.
Cosmetic contacts are non- prescription and anyone can wear them. They are color coordinated, and designed to change one’s eye color, to match a particular dress or outfit. However, non- prescription lenses can affect visibility. For instance, people with certain eye astigmatisms could not wear contact lenses unless their optometrist prescribes them.

Which Eye Surgery Is The Better Choice

Laser surgery is the most common, and perhaps the most popular surgery opticians use to correct most visual problems. Individuals who agree to laser surgery may eliminate their need for corrective glasses or contact lenses. The eyes are sensitive, and sometimes they are easily damaged, by injury, disease or faulty DNA structure.
Altogether there are four surgical procedures surgeons use to correct and improve one’s vision; LASIK, PRK, LASEK, and LTK. Each of these procedures are used to reshape, correct, or improve vision in one or both eyes.
LASIK Surgery
Nearly 95% of people with visual problems, seek Laser (LASIK) surgery as a permanent means of correcting the shape of their cornea, which is at the root of most vision problems. The eye surgeon uses a knife referred to as a microkeratome to meticulously crave a hinge in the eye’s cornea. Once the flap is folded backwards, it reveals the stroma, which is the middle part of the cornea.
With the aid of computerized technology, a digitally controlled excimer laser vaporizes a section of the stroma, and the hinged flap is replaced with a thinner, more flexible flap, allowing the eyes to adapt to higher prescriptions or corrective eyewear.
PRK or Photo Refractive Keratectomy
This is the type of surgery where the outer covering of the cornea is removed, and reshaped. With this type of surgery recovery time is a bit longer than LASIK surgery. The surgery removes the microscopic residue tissue from the outer area.
LASEK Surgery Works Best for Non LASIK Patients
Laser epithelial keratomileusis combines both PRK and LASIK surgical techniques. This surgery works best for people who cannot have LASIK surgery. No flap is cut in this procedure. Instead, a selected surface on the cornea is loosened, using an alcohol mixture. Once the section is loosened, it is gently moved to the side, just before the laser is set to reshape the cornea.
LTK Surgery Procedure
This type of surgery is less invasive than the laser surgery. Laser thermal keratoplasty is designed to correct astigmatism and farsightedness. This type of surgery is mild. The surgeon uses heat to alter the shape of the cornea. With the LTK surgery with is often called the “no touch” procedure, patients have a small risk of developing an infection or experiencing a loss of vision.
Summary
Surgery is definitely not for everyone. Optometrists recommend patients for one of these types of surgeries, depending on the severity of their vision. Not everyone is a good candidate, if they experience certain medical illnesses or diseases. Patients with minor eye problems might be a good fit. However, the final decision is up to the patient, and at the sole discretion of the optometrist.
Thousands of people have gotten good results from taking one of the above surgeries. Results can vary from patient to patient. Technology is advancing at an amazing rate. What seems like new technology today is actually old technology from yesterday. Surgery cannot guarantee anyone 20/20 vision, but it can provide some visual improvement.

How can I make my eyesight better

Our eyes are important hence the need to do all we can to take care of them. Below are different ways you can make your eyesight better.
Protecting your eyes has to start with the food that is on your plate. Nutrients like vitamin C and E, omega 3 fatty acids, zinc and lutein will help reduce vision problems that are age related such as cataracts and macular degeneration. Some of the foods you should eat are tuna, salmon, nuts, eggs, beams, green leafy vegetables, collards, kales, oranges and other citrus fruits such as lemons and fruit juices. Eating a balanced diet will also help you maintain a healthy weight which reduces the chances of getting obesity related diseases such as diabetes type 2 which is known to cause blindness in adults.
Stop smoking. Smoking increases the probability of getting cataracts, macular degeneration and optic nerve damage. If you have tried to stop smoking before but you started again, it is time you keep trying. The more times you try to quit this habit, the more likely you are going to succeed.
Wear sunglasses. The right type of sunglasses will help to protect your eyes from ultraviolet rays. A lot of exposure to these rays will make you get cataracts. Select sunglasses that block ninety to one hundred percent ultra violet rays. Wraparound lenses will help to protect your eyes from the side. Polarized lenses are going to reduce glare as you are driving. If you wear contact lenses, there are some that offer UV protection, however, it is a good idea to wear sunglasses for more protection.
Use safety eye wear if you work with airborne or hazardous materials at home or at work. There are some sports such as lacrosse, ice hockey and racquetball that lead to eye injury. You will need protection such as helmets with a protective face mask or sport goggles with lenses to protect your eyes.
Staring at the computer screen for a long time can lead to eye strain, blurry vision, dry eyes, trouble focusing at a distance, headaches, shoulder, neck and back pain. You need to make sure that the glasses or the contact lens that you wear is up to date and right for computer use. There are people who also need glasses to help them with glare and eye strain when they are on the computer. It is vital that you position your computer so that your eyes are on the same level with the top of your monitor. This will allow you to look slightly down at the screen. Try to avoid glare on your computer from windows and lights and if possible, use an anti glare. In the event your eyes get dry, try to blink more. After every twenty minutes, give your eyes some rest by looking at least twenty feet away for twenty seconds. Take fifteen minutes break after every two hours.
It is therefore clear that the above information will help you take care of your eyesight and make it better.

How Do Eyeglasses Help Your Eyes

Your eyes are the windows to your soul, at least this is what the older people say. When your eyes become dim, and weak, and can no longer see on their own, it’s time to find out why. Some common causes of eyesight deterioration are due to age, illnesses, and undiagnosed eye disorders.
In some cases, the optometrist may recommend corrective surgery to remove a foreign object, or repair a damage tissue. However, some vision problems are not that severe, and might not require such drastic treatment. In fact, the optometrist might recommend corrective eyeglasses to help improve your eyesight.
Optometrists have been prescribing eyeglasses to support, weak eyes for decades. This is normally the first type of treatment the optometrist may recommend. Nevertheless, the optometrist will not prescribe any corrective eye wear without a complete examination of the eyes first. The examination tells the optometrist a lot about your eyes, and how to treat them.
Understanding How Eyeglasses Help with Sight
To better understand how eyeglasses help with vision, you must first understand how the eyes work. The eyes help you to take in your surroundings, and what you are really seeing are different reflections of light. The light bounces off the objects, and enters through the cornea, and through the eyes lens, and eventually, onto the back of the eye, which is referred to as the retina. If the light fails to hit the retina straight on, the picture of what the eyes take in are distorted or blurry.
So, Why the Need for Eyeglass
When the light hits the retina head on, this means you have perfect vision. In cases where this does not happen, there is a potential vision problem. Some potential eye problems such as the cornea is not shaped properly, the light misses the retina when it enters through the lenses, the eyeball itself is too long or too short, or there might be some other underlying problem, the optometrist will need to find.
How Do Eyeglass Help Improve Sight
To find out the exact cause of your eye problem, the optometrist will need to perform so visual testing, using special equipment. Once the testing is complete the optometrist will write a prescription for eyeglasses. The prescription is given to the ophthalmologist, who in turn will fill the written prescription.
The prescription eyeglasses will enhance your vision, and allow by helping your eyes to refocus. When the light enters the lens of your glasses, they will redirect the light, so that it enters directly onto the retina. How much light the glasses absorbs, depends on the strength of the lenses. Strength or power in terms of eyeglasses is referred to as diopters.
The higher the level of diopters the optometrist prescribes, the greater amount of light the lenses are able to refract. In any case, once the light properly hits the eyeglass lenses in the right place, the eyes begin to see clearer, and objects are more visible, and life is wonderful, once again.
