  • Use a lens cleaner and wipe them dry with your lens cloth
  • Carry and store your glasses in their case when you’re not using them
  • Use both hands when removing your glasses
  • When setting your glasses down, make sure the lenses are not sitting flat on the table

How to care for sunglasses

If you take good care of your sunglasses, they can last for many years.

  • Handle your sunglasses with care, making sure not to bend or stretch them
  • Use a lens cleaner and soft lens cloth to wipe your lenses
  • Clean the sides and the nose pads
  • Take care not to place their lenses down flat on a surface
  • Avoid exposing your sunglasses to high temperatures
  • Do not wear them on top of your head as this can distort their shape
  • Store them in their protective case when not in use
Adjusting glasses

If your glasses frames have nose pads, you can adjust them by carefully pushing them in or out, depending on what you need.

  • If your glasses are sitting too high, gently push the nose pads outwards.
  • If your glasses sit too low, carefully push the pad arms behind the nose pads to bring them in a bit closer.
  • For acetate frames bring them to your optical dispenser. They will be able to help adjust them for you with their machine.
Cleaning glasses

Cleaning your glasses is a necessary part of maintaining clear vision. You can clean your glasses with a few common household items and some techniques to avoid damaging the lens. Cleaning your glasses regularly will help them last longer, so you won't have to buy a new pair as often.

To clean your eyeglasses, start by rinsing them with warm water to remove surface dirt. Then, mix a small amount of mild dish soap and lukewarm water together in a bowl. Soak your glasses in the soapy water for 30 seconds before removing them and rinsing them off with clean water.

Finally, dry your eyeglasses with a microfibre cloth or soft, lint-free towel. If you have anti-reflective lenses, make sure to avoid using household cleaners like Windex or ammonia-based products since they can damage the coating by breaking down its protective outer layer.

If your lenses get really dirty, try using a lens-specific cleaner instead of soap and water. Just spray the cleaner on both sides of your lenses and use a microfibre cloth to wipe it off. Make sure you don't use anything other than a microfibre or soft lens cloth to dry your glasses since paper towels or clothes can scratch them.

How to measure glasses frames

You'll find the size information stamped on your frame. Usually, you will find it on the inside arm of your glasses, for example: 52-17-140.

The first number is the lens width in millimeters, the second number is the bridge width in millimeters, and the third is the temple length in millimeters.

How to read glasses prescription

When you need glasses, they are custom-made, based on your prescription. All prescriptions contain three numbers, and the higher the numbers, the stronger the lenses. A typical prescription for glasses consists of:

  1. The sphere, which determines the vertical power

  2. The Cylinder and

  3. Axis.

How to test if my glasses block blue light?

A simple test that can be done at home to see if your glasses filter any blue light is a reflection test. Notice the colour that is reflected off the lenses. If the light is reflected back as blue, there is some amount of blue light being filtered.

Do I need to see an optometrist?

As we age, our eyes naturally undergo many changes, including a decline in our ability to see clearly. Early detection of eye problems can prevent suffering from vision loss, pain, and decreased quality of life. Your optometrist can help you identify conditions that can cause eye problems and how to treat them. Read more about eye tests.

Do I need anti-reflective coating on my glasses?

Anti-glare lenses are created with an anti-reflective (AR) coating, a thin layer that is applied to the lens itself and designed to reduce any reflections you might see through your glasses. This also reduces glare and ‘halos’ around light sources when driving at night.

What are photochromic lenses?

If you have ever seen a person whose glasses darken when they step outside, then they are wearing photochromic lenses. Photochromic lenses transition gradually from clear to dark as the wearer moves into sunlight.

Glasses pain behind ears

If you experience pain behind your ears when wearing glasses, an incorrect adjustment of the eyewear may be to blame. Adjusting the frames to fit your face can often eliminate nose or ear discomfort. An optical dispenser can check your eyeglasses to ensure they are fitted properly and fit comfortably behind your ears.

How do sunglasses protect your eyes from the sun?

The lenses of sunglasses contain a chemical that reflects light and absorbs ultraviolet (UV) rays from the sun. Sunlight reaching the eyes can damage their delicate tissues, which can affect vision. A good pair of sunglasses should block 99% or more of UV rays.

Signs my child needs glasses

Unless you have a child with a serious eye condition, you probably won't know your child needs glasses until they have an eye exam.
It can be difficult to tell if your child has vision problems, especially if the issues are occurring gradually or only in one eye. Some signs that your young child may need glasses include:

  • Eye rubbing
  • Frequent headaches and/or nausea
  • Squinting
  • Excessive tearing
  • Clumsiness
  • Behavioral issues/inability to focus
  • Extreme light sensitivity
  • Struggling to read
  • Sitting too close
  • Tired eyes

If you suspect your child has an eyesight issue, book an appointment with your optometrist who will be able to assess the problem and recommend a course of treatment or prescribe eyewear if necessary.

    When do I need new glasses?

    Optometrists recommend that glasses be replaced every one to three years. The time between replacements will be shorter if your lenses have become tarnished or if your prescription has changed. We recommend that everyone get their eyes tested by an optometrist at least once every 2 years.

    Do I need high index lenses?

    If your Sphere or Cylinder values exceed +/-3.00, your optometrist will often recommend high index lenses. Your optometrist or optical dispenser can help you to determine what type of lens will suit your prescription.

    How do I know if I need multifocal lenses?

    Multifocal lenses combine distance, intermediate, and near vision in one seamless lens. They are ideal for people who are both nearsighted and farsighted. You won't have to switch between two pairs of glasses: one for reading, the other for distance.
