Visual field testing is an important part of most standard comprehensive eye exams. Also sometimes known as perimetry testing, Visual field testing is a method to measure the entire scope of vision of an individual, including their peripheral/side vision.
 

The importance of visual field testing

Visual field testing is one of the most effective diagnostic tests in the detection of glaucoma. This is because when patients are affected by glaucoma, it is usually the peripheral vision that is affected by their condition first. However, it can also be used to detect central or peripheral retinal diseases, eyelid conditions such as drooping, optic nerve damage, and conditions that affect the visual pathways from the optic nerve to the area of the brain where this information is processed into vision.

Visual field testing is also an important part of monitoring for people who are considered to be at risk for vision loss from disease and other problems, including those who have been diagnosed with the following:

• Multiple sclerosis

• Hyperthyroidism

• Pituitary gland disorders

• Central nervous system problems (such as a tumor that may be pressing on the brain)

• Stroke

• Diabetes

• High blood pressure

In the ever-evolving world of vision correction, multifocal contact lenses have emerged as a game-changer for individuals seeking a seamless solution to address their presbyopia. As you navigate through life's various stages, your eyes may undergo changes that can impact your ability to focus clearly on objects at different distances. Multifocal contact lenses offer a convenient and effective way to combat this challenge, providing you with a versatile and comfortable option for correcting your vision.
 

What Are Multifocal Contact Lenses?

Multifocal contact lenses are specialized lenses designed to correct presbyopia, a condition that typically occurs as you age, making it difficult to focus on near objects. Unlike traditional single-vision lenses that correct either near or distance vision, multifocal contact lenses incorporate multiple prescriptions into a single lens. This innovative design allows you to enjoy clear vision at various distances, eliminating the need for separate reading glasses or bifocals.
 

How Do Multifocal Contact Lenses Work?

Multifocal contact lenses employ advanced optical technologies to provide seamless vision correction. These lenses feature distinct zones or concentric rings that correspond to different prescriptions for near, intermediate, and distance vision. As your eyes move and focus on objects at varying distances, the appropriate zone of the lens comes into play, ensuring a clear and comfortable visual experience.

There are two main types of multifocal contact lens designs:

• Simultaneous Vision Design: In this design, the lens incorporates multiple prescriptions simultaneously, allowing your eyes to utilize the appropriate zone based on the viewing distance. This design can take some time to adjust to, as your brain learns to interpret the different visual inputs.

• Alternating Vision Design: Also known as "segmented" or "translating" lenses, these lenses have distinct zones for near and distance vision. As you move your eyes or shift your gaze, the appropriate zone is positioned in front of your pupil, providing the necessary correction.
   

Eye Conditions That Multifocal Contact Lenses Can Treat

Multifocal contact lenses are primarily designed to address the following vision-related conditions:

• Presbyopia: As you age, the natural lenses in your eyes lose flexibility, making it challenging to focus on nearby objects. Multifocal contact lenses can correct this age-related farsightedness, allowing you to see clearly at all distances.

• Myopia (Nearsightedness): If you struggle to see distant objects clearly, multifocal contact lenses can incorporate a prescription to correct myopia, while also providing near and intermediate vision correction.

• Hyperopia (Farsightedness): For individuals with farsightedness, multifocal contact lenses can offer a solution by incorporating a prescription to improve distance vision, along with near and intermediate vision correction.

• Astigmatism: Some multifocal contact lenses are designed to correct astigmatism, a condition caused by an irregularly shaped cornea or lens, resulting in blurred or distorted vision.

Optical Coherence Tomography is a non-invasive imaging test that may be performed as a standard part of your regular, comprehensive exams, or you may be able to request this test as an addition to your usual exam.

Optical Coherence Tomography uses light waves to take cross-section images of your retina, which is the area of light-sensitive cells at the back of your eye that is responsible for receiving light and transmitting it into messages that are sent up to the brain. The technology behind OCT enables your eye doctor to see each of the different layers that make up the retina. By being able to see these and measure them, they can obtain a much clearer picture of the overall health and condition of your eyes.
 

Why are Optical Coherence Tomography scans important?

When you choose to have an OCT scan at fairly regular intervals, such as during your normal comprehensive eye exams, your eye doctor can compare newer results to previous ones. This helps them to build up a picture of the health of your eyes, and spot any changes which may be concerning, early, before they cause symptoms or have a permanent effect on your vision. 

Anyone can have an OCT scan, but they are particularly recommended for patients over the age of 25 who are concerned about the health of their eyes, or who are at risk of or already have diabetes, glaucoma or a family history of eye disease. This is because they can be used to spot the early signs of a range of eye diseases, including glaucoma, diabetic retinopathy, macular degeneration, disorders of the optic nerve, and more – even before you realize that you are affected.

Wearing contact lenses gives patients the flexibility and freedom to live life to the fullest, without some of the difficulties presented by wearing glasses. Many people who choose contact lenses do so because they don’t like the way that glasses look or feel, or because wearing glasses compromises their ability to perform certain tasks or activities, such as sports or jobs that require the use of safety goggles. 

There are lots of different contact lenses to choose from, with two of the most popular being daily disposables and toric lenses. 
 

Disposable Lenses

As their name suggests, these daily contact lenses are disposable. This means that they can and should be discarded at the end of each day rather than re-worn. Disposable lenses do tend to be a little more expensive than some repeat-wear varieties, but the benefits usually outweigh the cost. 

Some of the advantages of choosing daily disposable contact lenses include:

• You don’t have to clean them, which saves patients a great deal of time and hassle. It also helps save money in terms of the ongoing cost of cleaning solution. 

• Disposable lenses are also great for people with eye allergies. This is because with ordinary lenses, there’s an opportunity for deposits and microorganisms to build up. With daily disposables, allergens have less chance to attach themselves to the lenses and cause irritation and other allergy symptoms. 

• You don’t need to schedule regular replacements either, which makes wearing contact lenses easier on your schedule. 

• Disposable contact lenses are particularly good for people who have busy lives and are likely to cut corners when it comes to caring for their eyes or contacts since there is no cleaning or maintenance required.
   

Daily disposable contact lenses are available in a wide range of prescriptions, including those for patients with nearsightedness and farsightedness. Your eye doctor will be able to advise you if you are a candidate for disposable contact lenses. 

Myopia is a common vision problem affecting a large number of individuals worldwide. It occurs when the eye is unable to focus properly on distant objects, resulting in blurred vision. Myopia can develop during childhood and progress into adulthood if left unmanaged.
 

What Causes Myopia to Develop?

Myopia can be caused by a combination of genetic and environmental factors. If one or both parents have myopia, there is a higher chance that their children will develop the condition. Additionally, excessive screen time, lack of outdoor activities, and prolonged near-work activities such as reading or using electronic devices can contribute to the development of myopia. These lifestyle factors can lead to the elongation of the eyeball, resulting in the inability to focus on distant objects.
 

The Importance of Myopia Management

Managing myopia is crucial to prevent its progression and associated complications. High levels of myopia can increase the risk of developing eye conditions such as glaucoma, cataracts, and retinal detachment.

Additionally, severe myopia can lead to vision loss and significantly impact the quality of life. Early intervention and proper management of myopia can help slow down its progression and reduce the risk of these complications.

Telemedicine makes it easier to connect with your optometrist when an in-office visit is not necessary or not possible. A virtual eye care appointment allows you to discuss certain eye health concerns, follow-up needs, and symptoms through a secure video visit from home, work, or another private location.

All you need is a smartphone, tablet, or computer with a camera, microphone, and internet connection. The team will provide instructions before your appointment so you know what to expect and how to join your virtual visit.
 

How A Virtual Eye Care Visit Works

To schedule a telemedicine appointment, call our office or request an appointment online. Before confirming your visit, we may ask a few questions about your symptoms, medical history, and current eye care concerns. This helps us determine whether a virtual visit is appropriate or if you should be seen in person.

During your appointment, your optometrist will review your concerns, ask about your symptoms, and may guide you through simple observations or questions to better understand what is happening. In some cases, photos of the eye or eyelid may be helpful if they are clear and taken safely.

Astigmatism is a common refractive error that occurs when the cornea or lens of the eye is not perfectly spherical. Instead of having a uniform, rounded shape, the cornea or lens has a slightly more curved or irregular shape, resembling more of an oval or football-like appearance.

This irregular shape causes light to bend or refract unevenly as it enters the eye, leading to blurred or distorted vision. Astigmatism is often present from birth, but it can also develop later in life due to various factors, such as eye injuries, certain medical conditions, or the natural aging process.
 

Common Symptoms of Astigmatism

If you have astigmatism, you may experience a range of symptoms that can impact your daily life. Some of the most common symptoms of astigmatism include:

• Blurred or distorted vision, especially at a distance or when reading

• Difficulty seeing clearly at night or in low-light conditions

• Frequent headaches or eye strain

• Sensitivity to glare or bright lights

• Double vision or the appearance of halos around lights
   

These symptoms can vary in severity and may become more pronounced over time, especially if the astigmatism is left uncorrected.

Thanks to the advancement of lens technology, glasses lenses are no longer a single, one-size-fits-all solution. There are a variety of different lens types that can be used in glasses, giving patients greater flexibility and control over their vision than ever before.
 

Single Vision Lenses

Also known as monovision lenses, these lenses are designed to correct the wearer’s vision at just one distance and have a single prescription covering the entire surface of the lens. They are most often recommended for people who are either nearsighted (myopia) or farsighted (hyperopia) and who need glasses for a specific activity, such as driving or reading.
 

Progressive Lenses

Progressive lenses are multifocal lenses that can correct a patient’s vision at different working distances, ranging from far distance to reading distance. However, rather than designating different areas on the lenses for different distances with visible lines separating them, progressive lenses have a gradual change so that the wearer can smoothly transition from one lens power to another.
 

Bifocal and Trifocal Lenses

As you may have guessed from the name, bifocal and trifocal lenses have either two or three lens powers depending on which type you choose. Bifocal lenses support distance vision in the top half of the lens, and near vision in the lower half. Trifocal lenses support distance vision in the top third of the lens, intermediate vision in the middle segment, and near vision in the bottom third. Whichever variety you choose, you will see visible lines separating each segment.

Bifocal and trifocal lenses are recommended for patients who are nearsighted or farsighted, and those who develop presbyopia, which is the natural hardening of the eye lens that occurs as we get older. Presbyopia makes it harder for the lens of the eye to adapt to focus at different distances.
 

Multifocal Lenses

Multifocal lenses are the alternative name given to bifocal, trifocal, and progressive lenses.

Senior eye care is crucial for maintaining optimal vision and overall eye health as we age. As individuals grow older, they become more susceptible to age-related eye conditions. Regular comprehensive eye exams play a key role in early detection and management of these conditions, helping to preserve vision and prevent potential vision loss. By staying proactive with eye care and seeking timely professional assistance, seniors can enjoy clear, comfortable vision and ongoing eye health for years to come.
 

Common Eye Conditions in Seniors

As we reach our golden years, there are several eye conditions that become more prevalent. These conditions can have a significant impact on our vision and overall quality of life.

• Presbyopia: This condition affects near vision, making it difficult to focus on close objects. It is a normal part of aging and is typically addressed with reading glasses or multifocal lenses.

• Floaters and Flashes: As the vitreous inside the eye changes with age, it can lead to the perception of floaters (small dark spots or lines) and flashes of light. While often harmless, sudden onset of floaters and flashes may indicate a retinal tear or detachment and should be promptly evaluated.

• Age-Related Macular Degeneration (AMD): AMD is a leading cause of vision loss in older adults. It affects the macula, the central part of the retina, leading to blurred or distorted central vision. There are two forms of AMD: dry AMD and wet AMD, with the latter being more severe.

• Cataracts: Cataracts are a common age-related condition characterized by the clouding of the eye's natural lens. This can lead to blurry vision, glare, and difficulty seeing in low-light conditions.

• Glaucoma: Glaucoma is a group of eye conditions that damage the optic nerve, often due to elevated intraocular pressure. It can result in peripheral vision loss and, if left untreated, may lead to total blindness.

• Diabetic Retinopathy: For seniors with diabetes, diabetic retinopathy is a concern. It occurs when high blood sugar levels damage the blood vessels in the retina, leading to vision problems and potential blindness if not managed.

• Dry Eye Syndrome: Seniors may experience dry eye syndrome, characterized by insufficient lubrication and moisture on the surface of the eye. It can cause discomfort, redness, and fluctuating vision.

Migraines are a debilitating neurological condition that affects millions of people worldwide. One of the most common and disabling symptoms of migraines is light sensitivity, also known as photophobia. This heightened sensitivity to light can be a significant source of discomfort and pain for those suffering from migraines, making it difficult to function during an attack.

Photophobia is a common symptom of migraines, with up to 80% of migraine sufferers experiencing sensitivity to light during an attack. This sensitivity can be triggered by various types of light, including natural sunlight, fluorescent lighting, and even the glow of computer screens or smartphones.
