Time to explore two of the most common refractive errors: myopia and hyperopia!Normally, Light Is Focused Directly Onto The Retina Before we delve into what it means to be nearsighted or farsighted, let’s first talk about how a normal eye functions. Vision occurs when light enters the eye and, working together, the cornea and the lens refract light to focus onto a point at the very back of the eye called the retina. The retina converts this light into electrical impulses and sends them to your brain. Your brain then produces an image. When there are imperfections in the eye that prevent light from being focused perfectly on the retina, a refractive error occurs.
The Way The Eye Is Shaped Can Determine Vision Myopia Myopia, commonly known as nearsightedness, affects nearly 30 percent of the U.S. population. It occurs when light is focused in front of the retina, instead of directly on it. This happens when the cornea is too curved or the eyeball is too long. People who are nearsighted have an easy time reading, working on the computer and doing other close work. They struggle seeing when driving, reading a whiteboard at school, watching a movie or trying to identify faces from far away. Hyperopia When an eyeball is too short or the cornea isn’t curved enough, farsightedness–or hyperopia–is the result. This causes light to be focused behind the retina, making a farsighted person able to see far away but not close up. Only around 10 percent of Americans have hyperopia, making it much less widespread than myopia. Those who are farsighted can easily read an eye chart, but may have trouble reading the text book right in front of them. Consequently, farsightedness is often missed in simple vision screenings performed at school. For your next eye exam, come in and get your eyes checked by an eye care professional. We’ll not only ascertain your visual acuity but we will also assure that every aspect of your vision health is taken care of. Everyone Deserves To Have Good Vision If you have frequent headaches or eyestrain, you may have a problem with your vision. If you already have glasses or contacts and experience similar symptoms, you may just need your prescription updated. So whether you’re coming in for some new frames, renewing your prescription, or suspect that something in your vision might be off, we’d love to see you in our office.

You can do just about anything online nowadays. Whether you’re buying new clothes or earning a degree, if you have an internet connection, you can accomplish it online!But what about your regular eye exams? Is an online test sufficient enough for that?
Put simply, the answer is no! Online Eye Exams Aren’t All What They Seem Several online services offer the opportunity to take an eye test from the comfort of your own home. Using a series of lines, shapes and letters, they claim to provide an assessment of your vision in as little as 30 minutes. Many of these services even offer to have your test results verified by an optometrist who can then issue an eyeglass prescription. Although online vision tests may seem convenient, they only measure visual acuity and refractive error. Some branch out and test for other vision problems such as color blindness and light sensitivity, but none have the ability to focus on what’s most important--your eye health. A comprehensive eye exam from your optometrist is the only way to identify signs for serious vision problems such as cataracts, glaucoma, and macular degeneration. Self-Examination Poses Certain Risks Conducting a vision test without the aid of a qualified optometrist poses certain risks. Undiagnosed Vision Problems If vision problems such as cataracts, macular degeneration, and glaucoma exist, they will remain undiagnosed. Other overall health conditions can even present symptoms in the eyes. In fact, blurred vision is often one of the first warning signs of diabetes. If you are experiencing drastic changes in your vision, make an appointment with your optometrist. For more information about what we learn during a comprehensive eye exam, watch the video below!
Incorrect Prescription
Even though some services have their vision test results verified by an optometrist, without an eye care professional present while you take the online test, it’s difficult to ensure that the test is administered properly in the first place. Inaccurate test results may lead to receiving an incorrect prescription. Cost Online tests aren’t usually covered by vision insurance. If you do have insurance, your co-pay is likely less expensive than the fees associated with online vision services. We Care About Your Vision AND Overall Health We value our patients’ time and understand why the convenience of online vision tests may be alluring—but we also value your health! We want to ensure that you’re not only seeing clearly, but that you’re on the path to whole-body health as well.

Source: Online Your Eye Doctor From the moment your baby is born, they are constantly growing and developing—and so is their vision! Schedule Your Child’s First Visit Early! The American Academy of Optometry recommends babies receive their first comprehensive visual assessment at six months of age. Having your child’s eyes examined so early will ensure their visual development is on track and can help identify any problems that may be present. Your child’s optometrist or pediatrician may suggest you schedule their visit before their six month mark if they show certain risk factors including:
If you believe your child has any of these risk factors, talk with your optometrist about when you should schedule their first eye exam. What Happens During Their Visit? By the time your child is six months old, their sight should be fairly well developed in terms of their ability to focus, see color, and judge depth. It will continue to progress as they get older, but assessing their vision at this stage ensures their vision is clear and healthy so they can hit important developmental milestones such as building fine motor skills. Check out the video below to get a glimpse at how your baby sees the world! When examining your infant’s eyes, we look for:
Your child’s first visit isn’t just a time to examine their vision—it’s an excellent opportunity for parents to ask questions as well!

Nobody wears hard contact lenses anymore....right? Whoa there horsey! While many patients and the general public think that hard lenses are a thing of the past, this is definitely not the case. Hard lenses in their new form, rigid gas permeable contact lenses, are still a viable alternative for many types of vision corrections. They are terrific for those that want the sharpest vision possible, those that have astigmatism, those that have irregular corneas, post Lasik and refractive surgery patients, and those that want to actually improve their vision through corneal molding or Orthokeratology.
It is true that it takes a little more time to adjust to rigid gas permeable contacts lenses. When they are fitted correctly, the adjustment is very short and the lenses become very comfortable after adaptation. There are many other advantages to rigid gas permeable contact lenses. They last a long time. The average life span of a rigid gas permeable lens is about two years. In addition, if the lenses develop some scratches on the surface, these scratches can be polished out. The lenses are less subject to prescription changes than are soft lenses. Unlike soft lenses that correct astigmatism, the blinking of the eyes does not generally affect the clarity of the vision with "gas perms". Gas perms are also terrific for multifocal applications. It is also possible to adjust the fitting characteristics of "gas perms". This is becoming a "lost art". Doctors that are comfortable with adjusting "gas perms" can make the edges thinner, add power, loosen the lenses, make the lenses smaller, etc. No way is this possible with soft lenses. It is very common in our office to modify rigid gas permeable lenses to fine turn both the vision and the fitting characteristics of the lenses. This allows us to adjust the lenses to the finest fitting possible. So, are rigid gas permeable contacts (gas perms) the best lenses for all patients? I would definitely say "Maybe!". Each case is different, but "gas perms" are an excellent alternative for those patients that could best benefit from their unique characteristics. Be sure to ask your eye doctor if "gas perms" would be a good choice for you.

Choosing the right eyeglasses often depends on individual traits such as hair color, face size and even the type of vision correction you need. If you have an unusually wide face, for example, you may need to shop around for extra-large eyeglass frames. On the other hand, smaller faces may require a petite frame size. Unusually strong corrections also can make lenses look thick or distorted when eyeglass frames are oversized. Choosing Eyeglasses That Fit Your Lifestyle Besides complementing your looks, eyeglasses also need to suit your lifestyle. For example, a rough-and-tumble teenager who engages in all manner of outdoor activities will have far different needs for eyeglasses than an office worker who spends hours at a desk. Active people also may need to consider extra eye protection such as sports or safety goggles. For those who love fashion, designer eyeglasses with embellishments such as crystals and logos are a fun option. If you have reached your 40s, you will need to consider different eyeglass options for correcting near vision problems caused by presbyopia such as:
Your eye doctor or optician can advise you about the right fit for you, as well as discuss coatings and tints that can help you see your best in different circumstances such as low lighting at dusk. Source: Best Eyeglasses in Houston TX Best laser eye surgery options for correcting astigmatism in Bunker Hill and Houston TX Area12/20/2016 Sick of your glasses? If you suffer from astigmatism, you may be surprised to know that most eyes have it. This simply means that the front of the eye is a little more curved in one contour than the other. It is easily corrected with glasses (and less easily so with contact lenses) but what about laser eye surgery? What are your best options for getting rid of your astigmatism and your glasses?
The condition can be corrected as part of a treatment for short- or long-sightedness, whether that is a corneal procedure (LASIK or SMILE) or a lens replacement procedure. LASIK and SMILE If you’re under 50, both LASIK and SMILE provide very accurate correction for mild to moderate incidences of the condition. Higher degrees (above 4 dioptres) can also be corrected, but there may be some residual astigmatism after your procedure. That said, we often correct eyes with a lot of astigmatism and there is no significant residual error after surgery. Both LASIK and SMILE correct up to 10 dioptres of short-sightedness (myopia) including your astigmatism. LASIK also corrects long-sightedness (hyperopia) up to about 4 dioptres. Both procedures use a laser in different ways to change the shape of your cornea. They have been shown to have excellent safety profiles and are very accurate within their range. What about lens replacement? If you’re over 50, chances are you wear reading glasses or multifocals. Or you may take off your distance glasses to read. Either way, there is a difference between your correction for distance and near. Laser eye surgery aims to provide the maximum independence from glasses, although it doesn’t guarantee that you won’t need them for some tasks. Although it is possible to have LASIK or SMILE if you are over 50, it is increasingly common to have lens replacement surgery. This is exactly like cataract surgery, only without the cataract. It is corrected as part of this lens replacement procedure, either through corneal incisions or more commonly through the use of a toric intraocular lens (IOL). Toric IOLs are specially shaped to correct it. The trouble with them until fairly recently, was that if they were not precisely placed, they didn’t provide crisp vision. Accurate placement is now much more likely due to the technology used during the surgical work up and the procedure itself. Special iris-recognition tracking systems allow the toric IOL to be placed in precisely the right position to correct the condition and free you from dependence on glasses. How do I give myself the best chance of success with correcting it? Choosing a reputable surgeon greatly enhances your chances of success. There is no substitute for experience. Someone who is also a corneal specialist will also mean that should any complications arise, as they sometimes do, they can be managed with confidence. The right technology plays a big role where in comes to correcting the condition. Ask your surgeon about their success rates with toric IOLs. It is certainly true in our practice that the more sophisticated the technology for measuring the eye prior to surgery, the better the outcome. Our experienced eye doctors offer comprehensive vision examinations at our Houston optometry office and specialize in the diagnosis and treatment of a wide array of eye diseases, conditions, and problems. We use advanced diagnostic technology and vision correction products and are committed to improving the quality of life of persons in the Houston community through enhanced vision.

You don’t have the time to look into it, have an initial consult, come in for surgery and recover. You are crazy busy at work / have young kids / travel commitments or, like many of our patients, all of the above. This post looks at what busy people need to know about streamlining the whole process, from go to whoa.
Choose LASIK eye surgery LASIK has a well-deserved reputation as one of the miracles of modern medicine. You go in wearing glasses and you come out seeing clearly with the Vision Source Westview. LASIK has a remarkably quick recovery time, with many patients seeing 20/20 on the day of their procedure but you do need to allow a couple of weeks for the corneal flap to heal before resuming contact sports. SMILE may not give you 20/20 on the day of surgery, but you can usually see well within a few days of your procedure and the best bit is that you can resume all activities after just 5 days. If your surgeon doesn’t offer bladeless LASIK and SMILE, look for one who does. PRK (or ASLA) will give the same eventual outcome but you really do need to allow a couple of weeks of downtime before vision is restored so this is not the procedure of choice for busy people. Have surgery on a Friday Our experience has been that even the busiest people can take one day off work, especially for something as potentially life-changing as laser eye surgery. Having your procedure on a Friday usually means having your post-operative check-up later the same day. Once your surgeon has seen you and is happy with how the surgery went, you can go. Have your follow up locally All laser eye surgery requires follow up to ensure everything is healing and progressing as it should. Unless you live or work in the same suburb as your surgeon’s practice, it may make a lot more sense to have your routine aftercare appointments with your family optometrist. Many surgeons (ourselves included) reduce procedure fees to allow for external routine follow up locally. It is important that your surgeon liaise with your elected optometrist and that your optometrist provide feedback to the surgeon on your progress. At our practice, this is something we do a lot and we have established protocols with co-managing optometrists. Pop in for a suitability assessment If you are short on time and not even sure if you are suitable for a laser vision correction procedure, it may make more sense to come in for a suitability assessment first, to see if it is worthwhile proceeding to a full initial consultation with the surgeon. A suitability assessment is usually free of charge. It often involves a number of diagnostic tests and a conversation with a trained eye care professional (orthoptist or optometrist) who works closely with the surgeon and can liaise with them on which procedure, if any, may suit you best. Once you know you are definitely suitable, it makes more sense to plan your procedure and any associated downtime, including leaving contact lenses out for the required period. Ask for extra artificial tears Although LASIK has a remarkably quick recovery, it is associated with short-term dryness of the eyes. This manifests itself in inconsistent vision (rather than actually feeling dry) and can be worse in air-conditioned environments, especially if you are looking a digital screens a lot. Liberal use of artificial tears in the early weeks after LASIK can make your vision more consistent. You will be supplied with artificial tears but if you work in a busy office environment, don’t be afraid to ask for more. If you have to travel, see if it can be limited it to one trip of 2-3 nights Sometimes, travelling interstate to see a particular surgeon can make good sense. This may be because you have a complex ocular history or, it may be because you are very discerning and want the best eye surgeon you can afford. Either way, unless you are combining your trip with other events or you have family in town, it makes sense to minimise the time away from home. Ask staff how many nights you will need to stay. This varies depending on what procedure you are having. If you are having corneal surgery such as LASIK, SMILE or PRK, one night is the minimum but often 2 nights is recommended, depending on the surgeon’s schedules and if they acquire enough information about your eyes at your initial consultation. Lens procedures such as laser lens surgery and cataract require a minimum of two nights (for two eyes) but often 3 nights. You must also allow for the possibility that the surgeon may send you home without surgery. The risk of this happening can often avoided by making sure there is good communication with your local referring optometrist. With all these tips on board, laser eye surgery shouldn’t interfere with even the busiest lifestyle.

Monovision is the name for specific prescriptive contact lenses designed and fitted for patients with presbyopia. These prescriptive contact lenses act as a form of treatment for this age-related deterioration of vision, helping a patient to adjust their focus on objects near and far. What is Presbyopia? Presbyopia is the name given to the gradual deterioration of vision in aging eyes. This inevitable change in vision occurs as we get older, and usually begins around the age of 40 years. As we age the lens in our eyes become inflexible and rigid, preventing us from adjusting its shape. This inability to adjust the lens shape then creates difficulty for us in focussing on objects far and close to us. What are the symptoms of Presbyopia? If you have difficulty reading small print, or focussing on objects close to you, then you may be exhibiting symptoms of presbyopia. A common tell-tale sign of presbyopia is having to hold an object – especially reading material – at arm’s length for you to be able to focus on it clearly. Though these are symptoms of presbyopia, only an eye examination can confirm you have this condition. What are the treatments for Presbyopia? Monovision is one of the treatments for presbyopia, and works by fitting one eye with a distance lens (if required) and the other eye with a near lens. These two lenses, when worn, allows the wearer to achieve a clearer vision of both far and near distances. There are also other treatment options available, including bifocal glasses, progressive lenses, multifocal contact lenses, and prescription reading glasses. How do monovision contact lenses work? We all have one eye that is dominant, and another eye that is non-dominant. We rely more on our dominant eye to focus on far distances (as compared to our non-dominant), and our brain pays more attention to the visual information from this dominant eye. This means that when we fit a patient with monovision contact lenses to treat their presbyopia, we fit the non-dominant eye with a lens for near distances, and a contact lens for the dominant eye (if required) to correct distance vision. This then “tricks” the brain into thinking the contact lenses are part of the natural eye – and this process usually takes a fortnight, as the brain needs time to adapt to monovision contact lenses. Regardless of the type of contact lenses you wear, an annual eye exam is recommended to ensure the continued good health of your eyes. Schedule an appointment for an assessment and advice at Vision Source Westview in Houston, and we will be in touch with you shortly. Source: Monovision at Vision Source Westview More than 30 million people in the U.S. wear contact lenses and it’s easy to see why. They are freeing, allowing wearers to break out from behind the barrier that separates them from the world. They don’t interfere with sports or outdoor activities, and can even give you a whole new look via colored contacts, which allow you to change your eye color. While wearing contacts come with many benefits, there are potential problems that can occur. Aside from infection or irritation, there are times when your lens may feel as if it is stuck in your eye, or even missing. Can Contact Lenses Get Lost in Your Eye? No, it's not possible for your lens to get lost behind your eye. In most cases, the lens has slipped out of place or even fallen out. If this happens to you, one of the first things you should do is wash your hands. This helps you not to transfer bacteria into your eyes. Then, here are some simple approaches you can use to recover your contact lens:
Most lenses go back into place on their own with one of the above methods; if none of these techniques work, or if your eye becomes red or painful, be sure to call your eye doctor for help with removal. In conclusion, while contacts are simple and easy to use, they still require knowledge and diligent care. Knowing a few techniques to help when they get stuck will also be helpful in making sure your vision is at its best. To prevent your lens from getting stuck, a healthy practice for contact wearers is to use lens rewetting drops throughout the day. Also, never sleep with you contacts that aren’t designed for it and try not to wear your contacts for longer than eight to 12 hours daily, or the length of time recommended by your doctor.
