Presbyopia is a natural and inevitable part of aging that affects the eyes' ability to focus on close objects. Unlike other vision conditions, presbyopia isn’t caused by the shape of the eye or structural abnormalities but is instead a result of the eye’s lens losing its flexibility over time.
 

What is Presbyopia?

Presbyopia is a refractive error, meaning it affects how the eyes bend (or refract) light to focus it on the retina. Unlike nearsightedness (myopia) or farsightedness (hyperopia), which are caused by the shape of the eyeball or cornea, presbyopia is due to the aging of the eye's lens. Over time, the lens becomes less flexible, making it difficult to focus on nearby objects. Presbyopia isn’t a disease or an abnormality—it’s simply a natural consequence of the aging process.
 

What Causes Presbyopia?

The lens inside the eye changes shape to focus light on the retina, allowing us to see clearly at varying distances. When viewing nearby objects, the lens thickens and curves to increase its refractive power.

As we age, however:

• Lens Stiffening: The lens loses elasticity, making it harder to bend and adjust for near vision.

• Weakened Ciliary Muscles: The muscles that help change the shape of the lens may lose their strength over time, further reducing the eye’s ability to focus on close objects.

• Structural Changes: The lens also grows thicker and less transparent with age, which contributes to reduced focusing ability.
   

These changes are gradual, typically starting in a person’s 30s and becoming noticeable by their early to mid-40s.

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 treatments 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

Contact lenses have become a popular choice for individuals who want to correct their vision without the hassle of wearing glasses. Traditional contact lenses have been around for decades, offering a convenient alternative to eyeglasses. However, advancements in technology have given rise to a new type of contact lens – hybrid contacts.
 

What Are Hybrid Contacts?

Hybrid contacts are a revolutionary type of contact lens that combine the best features of both soft and rigid gas permeable (RGP) lenses. The rigid center corrects vision by providing precise clarity, while the soft skirt offers comfort and stability. This unique combination allows for the benefits of both types of lenses to be experienced simultaneously.

The central RGP lens of a hybrid contact is made from a rigid material that allows oxygen to pass through to the cornea, ensuring ample oxygen supply to the eyes. This ensures the overall health of the eyes, preventing dryness and reducing the risk of complications associated with limited oxygen flow.

Dry eye is a common condition that occurs when your eyes do not produce enough tears or when the tears evaporate too quickly. This can result in discomfort, irritation, and a gritty sensation in the eyes. Understanding the causes and symptoms of dry eye is crucial for finding effective treatment options. Tyrvaya offers a breakthrough solution for dry eye relief.
 

What Causes Dry Eye?

There are several factors that can contribute to the development of dry eye. The meibomian glands are responsible for producing the oily component of the tear film, which helps prevent evaporation of tears and maintains a smooth ocular surface. Meibomian gland dysfunction occurs when these glands become blocked, leading to a decrease in the quantity and quality of the meibum. This can result in evaporative dry eye, discomfort, and inflammation of the eyelid margins.

Another common causes is age. As we get older, our tear production tends to decrease, making us more prone to dryness. Hormonal changes, such as those that occur during menopause, can also affect tear production and lead to dry eye.

Environmental factors can play a role as well. Dry or windy climates, air conditioning, and excessive screen time can all contribute to dry eye. Additionally, certain medications, such as antihistamines and antidepressants, can cause dryness as a side effect.

Other underlying health conditions, such as autoimmune diseases like Sjogren's syndrome or rheumatoid arthritis, can also contribute to dry eye. In these cases, the body's immune system mistakenly attacks the tear glands, leading to reduced tear production.

Dry eye is a common condition that affects millions of people worldwide. It occurs when the eyes do not produce enough tears or when the tears evaporate too quickly. This can lead to discomfort, irritation, and even vision problems. If you are suffering from the discomfort of dry eye, MiBo Thermoflo can offer you a revolutionary solution.
 

Understanding the Causes of Dry Eye

Dry eye is a condition that occurs when the eyes do not produce enough tears or when the tears evaporate too quickly. There are several factors that can contribute to this condition, including environmental factors, certain medications, and aging. Environmental factors such as dry or windy climates, air conditioning, and excessive screen time can all worsen dry eye symptoms. Additionally, certain medications like antihistamines, decongestants, and diuretics can decrease tear production. Aging is also a common cause of dry eye, as tear production naturally decreases as we get older.

Meibomian gland dysfunction (MGD) and blepharitis are two common conditions that can contribute to the development of dry eye. MGD occurs when the meibomian glands, which are responsible for producing the oily layer of tears, become blocked or dysfunctional. This can lead to an inadequate amount of oil in the tears, causing them to evaporate too quickly. Blepharitis is an inflammation of the eyelids that can disrupt the normal functioning of the meibomian glands.

Eye care professionals use Optikam’s technology to capture more than 3 million eyewear measurements every year. The OptikamPad iPad app is a total dispensing solution that enables eye care professionals to successfully assist patients at all stages of the eyewear dispensing process, providing them with a unique and custom patient experience.
 

Optikam Posture Devise (OPD)

You may be surprised to learn that wearing glasses can and likely will affect your posture. Glasses lenses are most accurate when you look directly through their center. This means if your glasses are sitting too low or have slipped down your nose, you may find that you are subconsciously tilting your head back and this can affect your overall posture.

Optikam’s OPD measurement device is a cutting-edge tool that obtains eyewear measurements that take into account how the frame will be worn by patients, enabling the fit to be customized to their individual parameters. The ten measurements taken into account when determining each patient’s position of wear include:

• Monocular pupillary distance

• Multifocal seg heights

• Pantoscopic tilt

• Rear vertex distance

• Wrap (face form tilt)

• Near pupillary distance
   

This results in frames that not only look fantastic, but that also fit perfectly, remaining both comfortable and stable on the face without you needing to adopt an unnatural posture. The measurements obtained by the Optikam OPD measurement tool are immediately visible on your eye doctor’s tablet so that they can recommend which alterations to the frames are needed to ensure that the frames fit with precision and gives you the best visual experience.

A tonometer refers to the equipment that is used in tonometry – a test that measures the pressure inside your eyes, also known as intraocular pressure or IOP for short. Tonometry is rarely performed at your average comprehensive eye exam unless you are at high risk of or have been already diagnosed with glaucoma. Fortunately, tonometry can be used to detect changes in eye pressure before they cause any symptoms, enabling prompt action to be taken before your vision is affected.
 

About Glaucoma

Glaucoma is a common eye condition that occurs when the optic nerve, which connects the eye to the brain, becomes damaged. It’s normally caused by fluid building up in the front part of the eye, which causes the pressure inside the eyes to build. As the pressure increases, the optic nerve becomes increasingly damaged, and this prevents messages from being transmitted between your eyes and brain effectively. As a result, the patient’s vision becomes compromised. Without treatment, the level of vision loss will continue to increase. Unfortunately, any vision that has been lost as a result of glaucoma cannot be restored.

Most of the time, glaucoma develops very slowly which means that many people don’t realize that they are affected until some damage to their vision has already occurred. However, occasionally glaucoma can develop quickly, and symptoms do occur.
 

Glaucoma symptoms can include:

• Red eyes

• Intense headaches

• Tenderness around the eyes

• Eye pain

• Seeing rings/halos around lights

• Blurred vision

• Nausea and vomiting
   

If you notice any of these symptoms, it’s important that you make an appointment with your eye doctor right away so that you can be assessed. You are likely to have a tonometry test as part of this assessment.

For many individuals, dry eye disease is an ongoing struggle marked by irritation, burning, watery eyes, and inconsistent vision. While over-the-counter drops may offer short-term relief, they often fail to provide lasting hydration. In many cases, the issue isn’t a lack of tear production - it’s that tears drain away too quickly.

One innovative option designed to provide longer-term relief is LACRIFILL®, a modern approach to punctal occlusion that helps preserve your natural tears and restore balance to the ocular surface. 
 

What Is LACRIFILL® Canalicular Gel? 

LACRIFILL® is a soft, clear gel that is placed inside the eye’s natural tear drainage channels, known as the canaliculi. These tiny channels are responsible for carrying tears away from the surface of the eye and into the nasal cavity. 

For individuals with dry eye disease, tears often drain away too quickly. When this happens, the eye does not stay properly lubricated, leading to dryness and irritation. LACRIFILL® works by gently filling part of the drainage pathway, slowing tear outflow so that your natural tears remain on the eye longer.

Unlike traditional artificial tears that supplement moisture from the outside, LACRIFILL® helps you retain the tears your body already produces. This treatment is FDA-cleared and has been clinically studied for safety and effectiveness in managing dry eye symptoms. 

How Does LACRIFILL® Work?

Every time you blink, a thin layer of tears spreads across the surface of your eye. This tear film keeps your eyes smooth, hydrated, and protected from debris and infection. After serving their purpose, tears drain through small openings in the inner corners of the eyelids (called puncta), passing into the canaliculi and eventually into the nose. In dry eye patients, this drainage process may occur too rapidly, leaving the surface of the eye exposed and under-lubricated. 

LACRIFILL® forms a soft gel barrier within the drainage system, reducing tear loss and improving moisture retention. By keeping tears on the eye longer, it supports a healthier tear film and enhances overall comfort. 

The gel gradually biodegrades over time and is naturally reabsorbed by the body. Relief typically lasts several months, and the treatment can be repeated when necessary. 
 

Benefits of LACRIFILL®

LACRIFILL® offers several advantages for patients struggling with persistent dry eye symptoms: 

• FDA-cleared and clinically evaluated for safety and performance

• Quick, non-surgical procedure performed in-office

• No downtime or recovery period required

• Preserves your body’s natural tears rather than relying solely on artificial drops

• Provides extended relief that can last for months

• Biocompatible material designed to work harmoniously with the body

• Customizable treatment approach based on your individual tear drainage system 

For patients who are tired of frequent eye drop use, this longer-lasting solution can be life-changing. 
 

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 near 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.

Neuro-Optometric Rehabilitation

When most people think about vision problems, they picture issues with the eyes themselves. However, many visual difficulties actually begin in the brain. After a concussion, stroke, or other brain injury, the connection between the eyes and brain can be disrupted - causing symptoms that affect balance, reading, focus, and even daily comfort.
 

Brain Injuries and Vision

Your visual system is complex - about 70% of the brain is involved in vision processing. After a traumatic brain injury (TBI), concussion, or neurological event such as a stroke, the pathways that coordinate eye movement, focus, and perception can become impaired.

This can result in symptoms such as:

• Blurred or double vision

• Eye strain and headaches

• Difficulty reading or focusing

• Dizziness or balance problems

• Light sensitivity

• Problems with depth perception
   

These visual issues often persist long after other symptoms of a brain injury have improved, making specialized vision care essential for recovery.
 

What Is Neuro-Optometric Rehabilitation?

Neuro-optometric rehabilitation is a specialized form of vision therapy designed to retrain how the brain and eyes work together. Unlike traditional eye care that focuses on eyesight alone, this therapy targets the neurological processes behind vision. Our doctor evaluates how the eyes and brain communicate and creates a personalized treatment plan to rebuild these visual pathways. The goal is to restore comfort, coordination, and clarity - improving overall visual function and quality of life.
