Choose Aspheric Lenses For Better Vision And Aesthetics

In the last two decades, lens technology has worked tirelessly to improve aesthetics, comfort and optics in eyewear. Customers now have a wider range of options to choose from when they go to their dispenser to pick out lenses.

High index lenses with aspheric designs have become especially popular since coming into the scene about a decade ago, as they offer solutions to these 3 primary patient concerns.

1. Slimmer, more attractive profile

By using high-index lens materials and giving them an aspheric design, designers have managed to create lenses that are slimmer, thinner and lighter. Eyewear fitted with these lenses therefore has a more flattering profile design, mainly due to the flatter curves and less bulge in the frame.

Patients often worry about how changes in their prescription will affect the weight of their glasses. With conventional lenses, the bulk of the eyewear increases as the prescription gets stronger, affecting the choice of frames that the patient can go for. This is especially true with convex or 'plus' lenses used to treat farsightedness, as they are thicker in the center and thinner on the outside causing the lenses to bulge outside the frame.

With aspheric lenses, customers can choose from a wider range of frames, as the lenses produce minimal bulging even with stronger prescriptions due to their flatter curves. Edge thickness on myopia correction eyewear is also significantly reduced with aspheric lenses as compared to conventional ones.

2. Superior optics

One of the main problems with conventional lenses is that they tend to create a slight distortion in wider areas, as a result of the lens being slightly thicker at the center. With aspheric lens designs, you get better peripheral vision and almost no distortion when you look up or to the sides. This wider zone of clear imaging provided by aspheric lenses is again made possible by their flatter curves.

3. A more natural view of the world

For people wearing stronger corrections, aspheric lenses provide a more natural look than conventional lenses, as they fit closer to the face due to their slim design.

For farsighted patients, conventional lenses tend to magnify their view slightly, making the world appear distorted while also making the eyes appear bigger to on-lookers. To shortsighted patients, conventional lenses make things look smaller and give the wearer's eyes an unpleasant 'beady-eyed' appearance.

Aspheric lenses offer notably less distortion due to their flat curve and slim design, ensuring that the wearer's view of the world is perfectly natural while also making their eyes look more natural to everyone else.  Need more help?
