Astigmatism is an uneven curvature of the cornea and causes a distortion in vision. To correct this, a lens is shaped to correct the unevenness. Why does vision worsen as we age? As we grow older, the lens becomes less elastic. It loses its ability to change shape. This is called presb...

The focus adjustment allows -8.0D – +2.0D. If you require diopter outside of this range or astigmatism correction, eyeglass frames are provided that can be installed on the goggles, allowing you to use your own lenses. Unlike most other FPV goggles, the Goggles 2 have no buttons; control...

Astigmatism - the mirror is not ground symmetrically about its center (it might be slightly egg-shaped, for example); star images focus to crosses rather than to points. Coma - stars near the edge of the field look elongated, like comets, while those in the center are sharp points of lig...
Surgically induced astigmatism (blurred vision caused by the inability of the eye to focus) Posterior vitreous detachment (separation of the vitreous membrane from the retina causing floaters and flashes of light) Corneal ectasia (bulging of the cornea causing blurred vision) ...
Astigmatism: Light doesn’t focus on the retina correctly because the cornea or lens is misshapen. This can cause both near and far objects to look blurry. Presbyopia: Less flexible lenses and weaker muscles around them cause farsightedness. This happens to everyone as they get older. ...
