Computer aids come in many shapes and sizes. They range from decidedly low-tech devices to high-tech software programs which enable low vision sufferers to do the same computer tasks as normal-sighted people.

Low vision aids come in all shapes and sizes and serve a multitude of different purposes. A one-size-fits-all approach just won't do when it comes to choosing these devices, especially when you consider that a very wide range of eye problems can cause low vision.

The question of driving with low vision has recently become a very contentious issue. Many people argue that, since the 9/11 Commission Report of 2004 mandated the Secretary of Homeland Security to "issue standards for drivers' licenses", a golden opportunity had presented itself for introducing uniformity and equity into licencing standards.

As a minimum legal requirement to ensure safe driving, drivers should display visual acuity of 20/40 with or without corrective lenses. Restrictions generally apply to those with acuity between 20/41 and 20/70, limiting them to driving in daylight hours only.

Low Vision is a condition which is not remediable by using traditional corrective methods such as eyeglasses, contact lenses, medication or surgery. There are a myriad of causes which give rise to Low Vision, including glaucoma, macular degeneration, diabetic retinopathy, head trauma and stroke.

Maureen Cook shows how you can enjoy a perennial garden that offers the best of both worlds: maintenance-lite but still offering a visual delight even in the depths of winter.
