4 October, 2025What Are Prescription Glasses? Your Complete Guide
Prescription glasses in Perth are custom-designed eyewear that corrects vision problems caused by refractive errors, including myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia (age-related focus issues).
At Visual Eyes Optical Centre, we’ve been helping West Australians achieve crystal-clear vision since 1994. Prescription lenses are custom-made to your exact specifications after a comprehensive eye examination with our experienced optometrists.
Prescription lenses work by bending (or refracting) light, so it focuses precisely on your retina. When light hits the correct spot on your retina, your vision becomes sharper, clearer, and more comfortable—whether you’re driving along Mitchell Freeway, reading the newspaper, or working on your computer.
From navigating Perth’s roads to enjoying your favourite book, prescription glasses help your eyes perform at their best without strain or discomfort.
According to the World Health Organisation, over 2.2 billion people globally have vision problems, with approximately three-quarters of adults requiring optical correction. By 2030, the WHO estimates 3.36 billion people will experience vision problems due to increasing rates of myopia, driven by genetics and our growing reliance on digital devices.
Key Takeaways:
- Prescription glasses are precisely measured to your exact eye requirements for optimal vision correction
- Single-vision lenses are the most common type used in prescription eyewear
- Headaches and eye strain indicate it’s time to book an eye examination
- Genetics and increased screen time are causing a global surge in myopia—by 2050, half the world’s population will be myopic

What Are Prescription Glasses and How Do They Work?
Prescription glasses are corrective eyewear designed to eliminate blurred vision and provide sharp, clear sight. The lenses alter incoming light rays to ensure proper focus on your retina—the light-sensitive screen at the back of your eye.
There are two main types of corrective lenses:
- Concave lenses (minus lenses): For nearsighted (myopic) individuals, these redirect light further back to the correct focal point
- Convex lenses (plus lenses): These bring light forward, specifically designed for farsightedness (hyperopia) or age-related focus issues like presbyopia
With properly fitted prescription glasses from Visual Eyes Optical, you’ll immediately notice the difference—less squinting, fewer headaches, and a dramatically clearer view of your surroundings.
Vision Problems That Prescription Glasses Correct
Myopia (Nearsightedness)
Myopia makes it difficult to see distant objects clearly. This occurs when the cornea is too curved or the eyeball is too long. With myopia, light rays focus in front of the retina instead of directly on it, making distance vision blurry. Myopia is often hereditary and typically becomes apparent during childhood, adolescence, or early adulthood.
Symptoms include:
- Squinting to see clearly
- Eye strain leading to headaches
- Blurred vision when viewing objects beyond a certain distance
- Difficulty reading road signs whilst driving
Hyperopia (Farsightedness)
Hyperopia occurs when the cornea is flatter or the eyeball is shorter than normal. Light focuses behind the retina rather than directly on it, primarily affecting near vision.
Symptoms include:
- Eye strain or fatigue
- Blurred vision when reading or performing close-up work
- Persistent headaches
Prescription glasses with convex lenses converge light rays to focus correctly on the retina, sharpening near vision and eliminating eye strain during close-up tasks.
Astigmatism
Astigmatism develops when the eye’s lens or cornea is more oval-shaped than round. This irregular curvature causes light to focus at multiple points rather than one precise spot, resulting in blurred or distorted vision at any distance.
Due to the eye’s irregular shape, toric lenses are often prescribed to provide clear vision. These specialised lenses are custom-designed to correct specific distortions at precise angles.
Presbyopia
Presbyopia is an age-related vision decline where individuals gradually lose the ability to focus on nearby objects. This condition typically begins around age 40 as the eye’s lens becomes less flexible. Tasks like reading or using mobile devices become increasingly difficult.
Progressive and multifocal lenses correct presbyopia by providing a gradual transition from distance vision at the top of the lens to near vision at the bottom, allowing clear sight at all distances without switching between multiple pairs of glasses.
Common Terms in Your Glasses Prescription
Understanding these terms helps you make informed decisions about your eyewear:
- Sphere Power: Measures the lens strength needed to correct myopia or hyperopia
- Cylinder Power: Indicates the lens power required to correct astigmatism
- Axis: The direction of astigmatism correction, measured in degrees
- ADD (Addition): The additional magnifying power required for multifocal prescriptions
- Pupillary Distance (PD): The distance between your pupils’ centres, essential for proper lens alignment (also called Binocular PD or Monocular PD)
Types of Prescription Glasses Available at Visual Eyes Optical
Prescription glasses come in various designs to suit your lifestyle, fashion preferences, and visual requirements. Here are the most common options:
Single Vision Lenses
These lenses have one focal power and correct either nearsightedness or farsightedness (but not both simultaneously). They’re ideal for individuals with one primary vision need and are particularly popular among younger patients.
Progressive Lenses
Progressive lenses correct presbyopia whilst providing seamless transitions between multiple focal distances. They offer gradual changes in lens power, creating a more natural viewing experience without the visible lines and abrupt focal jumps associated with bifocals and trifocals. These represent the premium choice for multifocal correction.
Computer (Occupational) Glasses
Computer glasses are specifically designed for extended screen use, reducing discomfort, eye strain, headaches, and dry eyes associated with prolonged digital device use. These lenses optimise intermediate and wide-screen focus, perfect for Perth’s office workers and remote professionals.
Bifocals and Trifocals
These lenses provide two or three distinct focal lengths for different viewing distances. Bifocal lenses feature an upper portion for distance vision and a lower section for near tasks like reading. Trifocal lenses include an additional middle section for intermediate vision, particularly useful for computer work.
Lens Upgrades to Enhance Your Prescription Glasses
Photochromic Lenses
Photochromic lenses automatically adapt to changing light conditions—darkening in UV sunlight and becoming clear indoors. They provide continuous UV protection, shielding your eyes from harmful radiation. Perfect for Perth’s sunny climate, these lenses eliminate the need to constantly switch between prescription glasses and sunglasses when moving between indoor and outdoor environments.
Polarised Lenses
Polarised prescription sunglasses are specifically designed to reduce glare from reflective surfaces like water, roads, and glass. They incorporate a special filter that manages light wave transmission, making them ideal for driving around Perth, beach activities, and outdoor pursuits.
Essential Lens Coatings
Lens coatings significantly enhance your prescription glasses’ performance and durability:
- UV Protection: Shields your eyes from the sun’s harmful ultraviolet rays
- Scratch-Resistant Coating: Maintains lens clarity, prevents scratches from affecting vision, and extends the lifespan of your eyewear
- Anti-Reflective Coating: Reduces glare from reflections off water, windscreens, glass, and other reflective surfaces, improving visual comfort

Why Regular Eye Examinations Are Essential
Scheduled eye examinations keep you on top of your eye health and ensure your prescription remains current. Here’s how often you should have your eyes tested:
Recommended Eye Examination Frequency
Adults (18–60 years): Every 1–2 years for those without vision problems. Annual examinations are recommended if you wear glasses regularly or have a family history of eye conditions. Regular checkups detect early signs of eye disease before they progress.
Children: Annually or as advised by your optometrist. Children’s eyes develop rapidly, and early detection of vision problems is crucial for learning and development. Infants should have their first eye examination at six months, followed by another at three years, then annually once school begins.
Seniors (60+ years): Annual examinations are essential as older Australians face increased risks of glaucoma, diabetic retinopathy, macular degeneration, and cataracts. Regular eye examinations are vital for early detection and management of age-related vision conditions.
Warning Signs You Need New Prescription Glasses
Vision changes often occur gradually. Book an eye examination at Visual Eyes Optical if you experience:
- Frequent headaches: Particularly after reading, computer work, or screen time
- Blurred or double vision: Difficulty focusing on near or distant objects indicates your current prescription may no longer be effective
- Squinting or night vision difficulties: Struggling to see clearly in low-light conditions or constantly squinting are common indicators of deteriorating eyesight
Consequences of Ignoring Vision Changes
Delaying eye examinations can lead to:
- Increased accident and fall risk: Poor vision impairs balance and depth perception, increasing the risk of falls and misjudging distances, particularly when driving
- Reduced performance: Reading, writing, and screen-based tasks become progressively more challenging
- Persistent eye discomfort: Ongoing eye fatigue, discomfort, and dryness make daily activities unnecessarily tiring
