I feel like my glasses don’t “fit” my eyes
Do any of these situations sound familiar?
I often feel the need to rub my eyes, or take my glasses off to give my eyes a rest.
By evening, I feel like my glasses have taken a toll on me.
I had my eyes checked and got a new pair of glasses, but I feel like my vision isn’t as sharp as it should be.
My vision is not as clear when I move my eyes toward the edges of my glasses.
Your eyes could be telling you they need a better lens.
Just like a camera lens, an eyeglass lens has optical aberrations as soon as your line of sight goes out of the optical center of the lens.
The 2 main aberrations found on ordinary lenses are:
- Astigmatic error.
When your line of sight goes off center, the lens power seen by the eye is not the same in all the directions. The horizontal power becomes different from the vertical power.
- Power error.
The corrective power of the lens in the center is different from the power in the periphery. When looking off-axis, the image formed on the retina is less sharp.
The Nikon lenses that fit your needs
With ordinary lenses, the combined effects of astigmatism and a lens power error result in a small blur effect that you may not notice at first, but will affect your vision and make your eyes tire more easily.
Most Nikon lenses have an aspheric design so the power error and astigmatic error are corrected in the best possible way.
Nikon has created a wide range of lenses with different designs (spheric, aspheric, and double aspheric), refractive indexes (providing different lens thicknesses) and protective coatings (anti-glare, anti-scratch, easy-clean) to meet your needs and provide a sharp, clear performance.
