There are many different types of prescription lenses. Your EyeQ Optometrist will recommend the right type for you depending on your prescription and also your lifestyle. We know all the variety can make things confusing at times, so here’s a straightforward description of each type and what they offer the wearer. Please feel free to ask your EyeQ Optometrist if you’d like more information on our lens options.
Probably the most common lens type, single focus lenses have one single prescription across their entire surface and are suitable at all stages of your day – whether you need your glasses for driving, working or reading.
If you need to wear glasses for both distance and near vision, you could wear separate pairs of single vision glasses dedicated to each task. For increased convenience you could explore the use of multi focus lenses.
Eyes change throughout our lives, gradually losing the ability to focus on close objects. During our mid-forties, the lenses in our eyes become stiffer, and the muscles that control them change – which eventually causes blurred vision. This is called Presbyopia, and it happens to all of us. You’ll probably find yourself holding books, newspapers or product labels further away, or needing more light in order to read clearly.
Your EyeQ Optometrist may recommend multi focus lenses if you are experiencing Presbyopia. This gives you the convenience of having natural vision at all distances in one pair of glasses. These also have a smooth cosmetic appearance with no visible line on the lens.
A bifocal lens provides distance and near vision in one lens. The near vision correction of the lens is contained in a segment, often visible on the front of the lens. This segment provides the extra power necessary for you to read clearly.
When you work at a computer for any length of time, it’s common to experience eye strain, blurred vision and red eyes. This is because the visual demands of computer work are unlike those associated with most other activities.
If your glasses are up-to-date (or you don’t need prescription eyewear for most tasks) and you continue to experience eye discomfort during computer work, your EyeQ Optometrist may recommend a pair of customized computer glasses. These special-purpose glasses are prescribed specifically to reduce eye strain and give you the most comfortable vision possible at your computer.
Computer glasses optimize your eyesight when viewing your computer screen and may include special lens coatings to reduce glare and/or a tint designed to eliminate eye strain.
Without computer eyeglasses, many people end up with blurred vision, eye strain, and headaches. Some try to compensate for their blurred vision by leaning forward, or by tipping their head to look through the bottom portion of their glasses. This can result in a sore neck, sore shoulders and a sore back.
Polarised lenses are very popular for anyone who spends time outdoors, but can also reduce glare while driving. These lenses cut glare and haze so your eyes are more comfortable and vision can be better.
Polarized sunglasses can also be very useful indoors for light-sensitive people, including post-cataract surgery patients.
Photochromic lenses such as those made by Transitions Optical are clear (or nearly clear) indoors and darken automatically in response to sunlight outdoors. They also protect your eyes from 100 percent of the sun’s harmful ultraviolet radiation – this means you will always be completely protected when wearing Transitions.
Photochromic lenses also are great for kids, who tend to spend more time outdoors than most adults. Experts say most UV damage is done in the first two decades of our life, so protecting your child’s eyes early on could pay dividends later.
Polycarbonate lenses are super tough material and help protect your child’s vision by holding up to rough-and-tumble play or sports without cracking or shattering. Many eyecare practitioners insist on polycarbonate lenses for children’s eyeglasses for safety reasons.
The material is lighter than standard plastic or glass, which is good news for youngsters with strong prescriptions. This also means they don’t constantly slide down on the nose.
Overexposure to UV rays has been associated with cataracts and other eye problems, so having a coating on your lenses which protects you from harmful UV rays is considered good eye health and will often be recommended by your EyeQ Optometrist.
Many eyeglass lenses come with a factory-applied, scratch-resistant coating to keep the lenses clear for as long as possible, even when worn by children.
