The Essential Steps to Choosing Contact Lenses
Selecting the ideal contact lenses Toronto is a structured process that must always lead through professional care. Because contact lenses sit directly on your cornea, a precise fit is critical to maintaining long-term eye health.
1. Schedule a Professional Contact Lens Exam
A standard glasses prescription is not the same as a contact lens prescription. An optometrist in North York must measure the specific curvature of your cornea and assess your tear film to determine if you are a suitable candidate.
2. Assess Your Daily Lifestyle and Environment
Consider your habits and environment. Do you work long hours in front of an air-conditioned office screen in Saigon? Are you active in outdoor sports? Your daily routine heavily influences whether daily disposables or extended wear lenses will suit you best.
3. Select the Ideal Lens Material
Work with your eye care specialist to choose between soft silicone hydrogel lenses (excellent for oxygen permeability and dry eyes) and rigid gas permeable (RGP) lenses, which often provide sharper vision for complex prescriptions.
4. Complete a Professional Fitting and Trial Period
An eye care professional will place trial lenses on your eyes to check the alignment and movement. You will test these lenses for a few days to ensure they remain comfortable throughout your typical daily activities.

Key Factors in Selecting Your Lenses
1. Replacement Schedules
How often are you willing to replace your lenses? This choice impacts both convenience and hygiene:
- Daily Disposables: Worn once and thrown away at night. These are highly hygienic and perfect for resisting dust and seasonal allergens during changing seasons in the Greater Toronto Area (GTA).
- Monthly or Bi-Weekly Lenses: Removed nightly, cleaned, and reused for 2 to 4 weeks. These are cost-effective but require a strict, disciplined cleaning regimen.
2. Vision Correction Needs
Your specific vision condition dictates the optical design of the lens:
- Spherical Lenses: Used to correct standard nearsightedness (myopia) or farsightedness (hyperopia).
- Toric Lenses: Specifically engineered to correct astigmatism by preventing the lens from rotating on the eye. If you require these specialized options, you can explore our customized options for astigmatism contact lenses Toronto.
- Multifocal Lenses: Designed for individuals with presbyopia, allowing clear vision at near, intermediate, and far distances simultaneously.
Sizing and Fit Specifications: How to Choose Contact Lenses For My Eyes?
Every pair of eyes has a unique geographical landscape. When an optician or eye care practitioner measures your eyes, they map out the exact dimensions required to ensure a lens rests stably on the tear film.
Here is how sizing parameters change for four distinct eye types:
1. Flat Corneas (Low Curvature)
Some individuals naturally possess a cornea with a gentler, more gradual slope. If you place a standard off-the-shelf contact lens on a flat cornea, the lens will fail to grip the surface. It will move excessively with each blink, leading to variable focus and a constant feeling of an external object in the eye.
The Sizing Solution: Your optometrist will prescribe a lens with a larger Base Curve (BC) value, generally ranging from 8.8mm to 9.0mm. This flatter interior profile allows the lens to lie smoothly against the eye without shifting.
2. Steep Corneas (High Curvature)
Conversely, a steep cornea features a high, prominent central dome. A standard lens placed here will create a suction effect, gripping the edges too tightly. This tight lens syndrome traps metabolic waste, starves the corneal tissue of essential oxygen, and causes severe redness by the end of the day.
The Sizing Solution: This structural profile requires a smaller, steeper Base Curve value, typically between 8.3mm and 8.5mm. This distinct curve safely clears the high dome while maintaining comfortable, uniform contact.
3. Large Corneas or Wide Irises
If the physical diameter of your clear cornea or the visible colored iris is wider than average, a conventional contact lens will not provide full coverage. The lens edges can rub against the sensitive limbal zone, which is the border where the cornea meets the white sclera, causing chronic dry patches.
The Sizing Solution: Specialists address this by adjusting the total Diameter (DIA) of the lens upward, frequently selecting sizes from 14.5mm to 14.8mm to ensure complete protection and structural stability.
4. Narrow Eyelid Openings (Small or Monolid Eyes)
Many individuals with smaller eyes or monolid eye shapes face practical difficulties with contact lenses. The issue is rarely the size of the cornea itself, but rather a narrower horizontal and vertical eyelid opening. Attempting to insert a standard or large lens can be highly frustrating, and the natural tightness of the eyelids can continuously push the lens out of alignment.
The Sizing Solution: For an optimal blend of comfort and ease of insertion, a compact lens Diameter (DIA) of 13.8mm to 14.0mm is typically recommended. These slightly smaller lenses pass easily between the eyelids and sit comfortably centered without constant lid friction.

Why a Professional Fitting Matters for Your Safety
Contact lenses are classified as medical devices. A poorly fitted lens can restrict oxygen flow to the cornea, cause corneal scratching, or lead to serious infections.
During a dedicated contact lens fitting Toronto, your eye care expert performs several specialized assessments to guarantee long-term safety and visual clarity.
As shown in the clinical outline above, a professional fitting consists of three foundational pillars:
- Vision Testing: Ensuring your prescription accounts for the exact distance between the lens and your eye.
- Measuring Your Cornea: Using precise digital topography to map the unique shape and size of your eye surface.
- Assessing Eye Health: Checking for underlying issues like dry eyes or seasonal allergies that might make certain lens materials uncomfortable. If you experience severe dry eyes, our team can guide you to the best contact lenses for dry eyes Toronto options.

Frequently Asked Questions: Finding Your Perfect Contact Lenses
How do I know which contact lenses are best for me?
Your optometrist matches lenses to your exact prescription, eye anatomy, and lifestyle. If you work long hours in front of screens in dry, heated North York offices, you will need premium lenses designed specifically for high moisture retention.
What should I look out for when buying contact lenses?
Prioritize high oxygen permeability (Dk/t) to keep your eyes healthy and white. Choose modern materials like silicone hydrogel, and always buy directly from a certified clinic to avoid unverified or poorly stored online counterfeits.
What contact lenses are good for Sjogren's syndrome?
Sjogren's syndrome causes severe dry eyes. Large-diameter Scleral Lenses are highly recommended because they vault completely over the cornea, trapping a continuous reservoir of sterile saline underneath to keep the eye lubricated all day.
How do diameter and base curve work for small or monolid eyes?
Small eyes usually just have a narrow eyelid opening, not a smaller cornea. To ensure easy insertion and prevent eyelid friction, your optician will select a compact diameter (13.8mm to 14.0mm) and a base curve that mirrors your eye slope.
Can I use contact lenses if I have astigmatism?
Yes, absolutely. Astigmatism can be completely corrected using custom-weighted toric lenses. These are designed so they do not rotate when you blink, keeping your vision consistently sharp and clear.
Which contact lenses are best for dry eyes?
Counterintuitively, high water content lenses can worsen dryness because they pull moisture away from your natural tear film. For dry eyes, choose low-water silicone hydrogels that breathe well, or daily disposables that eliminate irritating protein buildup. Advanced water-gradient options, such as Alcon Dailies Total1 or Acuvue Oasys Max 1-Day, provide a gentle cushion of moisture that protects your eyes all day.
Can I use my glasses prescription to order contact lenses?
No. Glasses sit about 12 millimeters away from your face, while contact lenses rest directly on your tear film. Because the distance changes, the optical power shifts. Contact lens prescriptions also include crucial base curve and diameter measurements that glasses exams do not cover.
Can I sleep or swim while wearing my contact lenses?
No, both carry severe infection risks. Sleeping starves the cornea of oxygen, multiplying the risk of corneal ulcers. Swimming or showering introduces dangerous waterborne bacteria that get trapped behind the lens, which can cause permanent vision damage.
