What Style of Eyeglass Lenses are Right for You?
What eyeglass lenses are right for you?
“The eyes are the windows to the soul.” If this is true then the lenses you choose for your eyewear play the role of gatekeeper, right? Each person is unique and has different needs for what lenses are right for them. There are a vast variety of choices, so how do you know what is right for you? Or what the function of each type of eyewear lens
Let’s start with the basics: Single Vision, Bifocals, Trifocals, & Progressives
- Single Vision – this is usually prescribed for people under 40 or those who want clear reading vision but do not need to see things further away while they are using their glasses.
- Bifocals – this is usually prescribed to people over 40 whose ability to focus has diminished over the years, which is called presbyopia. This is age related and causes a change in the eye’s natural lens. Bifocal lenses are split into two parts, the upper part is for distance and the lower part is for close vision, such as reading.
- Trifocals – this is just as it sounds, simply bifocals with a third section. This third section is for those who have trouble focusing on things within arm’s length, such as computer screens
- Progressives – this is most similar to trifocals except without the lines making them the most popular choice for multifocal correction. Their performance is strongly dependent on the quality of progressive used and how the different powers are blended into the lens.
Now let’s take a look at the modern eyeglass lenses, which are lighter, thinner, and more scratch resistant than common plastic lenses:
- Polycarbonate lenses – these are great lenses for athletes because they are impact resistant and are not easily scratched or broken, which makes them a good choice for children, too. They also have built-in ultraviolet protection from the sun
- Trivex lenses – lightweight, impact resistant, and thin, they are very similar to polycarbonate lenses, but typically provide better vision correction
- High Index Lenses – this is a good choice for those who need a stronger prescription. They are lighter than the common “coke bottle” lenses and because of that, they are much more comfortable to wear
- Aspheric Lenses – a typical lens is spherical in shape, aspheric lenses have different levels of curvature over its surface to provide clearer vision and not make the eyes seem large or small depending on the prescription
- Photochromic Lenses – this type of lense can change from clear to tinted when exposed to sunlight. They are made from either glass or plastic and have a high ability to block out harmful ultraviolet rays from the sun
- Polarized Sunglasses – water and flat surfaces can cause unwanted glare, but polarized lenses reduce the harmful reflection of the sun’s ultraviolet rays
The eyeglass lens is the tool that allows your eye to focus light appropriately on the retina. For example, those who are nearsighted may need a lens that curves inward or that is concave, but for those who are farsighted, a lens that curves outward or that is convex is used. Those with astigmatism, which causes distortion in shape, will require a cylinder shaped lens.
There are also several different types of lens treatments to choose from:
- Mirror Coatings – this type of coating is purely cosmetic and allows the eyes to be hidden from view. It comes in a variety of colors, such as gold, silver, and blue
- Tinted Lenses – tinted lenses can be beneficial to one’s vision or make your eyes more comfortable under bright lights and a light tint can help hide “crow’s feet” or “laughter lines” around the eyes
- Anti-reflective Lenses (Glare Free Lenses) – this type of lens makes the vision clearer and can help reduce “halos” around light and have a pleasing cosmetic appearance
- Scratch-resistant – this type of coating protects your lenses from getting scratched
- Ultraviolet Protection – this is a common thing with eyewear, most glasses today will come this which helps protect your eyes from ultraviolet rays which can lead to macular degeneration and cataracts
No matter what type of eyewear you choose, always store them in a clean, dry place away from potential danger, use a non-lint cloth to keep them spot-free, and visit your doctor annually to be sure your prescription is up-to-date.
