Eyeglasses

How Do I Know If I Need Glasses?

Book a comprehensive eye exam and have your vision checked if you experience:

• Difficulty reading up close

• Poor night vision

• New or frequent headaches

• Double vision

• Blurred distance vision

Depending on your symptoms, you might need a single vision lenses that improves your vision at distance, intermediate or at near. In cases where both distance and near vision need correction, you may need bifocal or trifocal lenses, which are a single lens with multiple prescriptions separated by a line. In most of these cases, patients prefer progressive lenses, which contains multiple lens powers without a visible line or sections.

Lenses come in different materials:

• CR-39 : Standard plastic lenses

• Polycarbonate: The most popular impact-resistant material. They are slightly lighter than CR-39.

• Index 1.67: These lenses are recommended for “stronger” prescriptions (+/-3.00 and up). This lens material is 20% thinner than polycarbonate.

• Index 1.74: These are 10% thinner than index 1.67. A great option for prescriptions +/-5.00.

• Trivex: Another impact-resistant lens. It has a similar thickness to polycarbonate. However, Trivex will provide a little more clarity than polycarbonate.

Other lens add-ons:

• Scratch-resistant, anti-smudge coating: These are standard in all of our lenses. To avoid scratching your lenses when wiping them down, make sure to use a damp microfiber cloth.

• Anti-reflective coating: This coating improves contrast and reduces glare. It also improves the appearance of a lens by making it less reflective.

• Blue-blocking lenses: These lenses have recently become very popular for people working on computer screen or their phones all day and late in the evening.. They are often associated with reduced eye strain and better sleep.

• Polarized lenses: These are a great option against sun glare. Polarized lenses have a special chemical that filter light. Think of it like a miniblind hanging in front of a window. Only light that passes through the blind’s openings can be seen. As a result, objects look crisper and clearer. People who fish, in particular, find polarized sunglasses drastically cut the glare and help them see into the water.

• Photochromatic lenses: These lenses darken when exposed to UV light. They can be either grey or brown. Lately, the Transitions brand created lenses that can turn blue, red, emerald, or purple!

• Tints: Sunglass tints can be made in varying shades and colors. Gradients can also be created. Mild tints can also be added to a regular pair of glasses to improve comfort (for those complaining of light sensitivity) or simply to suit your style.
  

What Is Done During an Eyeglasses Exam?

The exam starts with a history if your medical health, questions regarding your current visual problems, your current visual demands (type of work done, amount of screen time, age), and your previous prescription. Your eyeglasses exam may include:

• Visual Acuity testing

• Eye movement evaluation

• Pupil reflex evaluation

• Depth perception testing

• Color vision testing

• Ocular health screening

Depending on your prescription, your health, and family history, Dr. Lingad may suggest further testing to evaluate your ocular health. For example, if you have a strong family history of glaucoma, you may need visual field testing.
