Wearing eyeglasses is important for those who have weak eye-sight and live in a polluted city. Contact lenses could be worn to adjust eyesight but dust is one of the biggest threats. To solve the issue of having to go to an optometrist who decides the prescription after evaluation of a person’s eyesight and to save on paying every time, researchers have come up with self-adjustable glasses from Eyejusters. Eyejusters is a British company that wants a cost-effective way to deal with declining eye-sight.

They have especially developed it keeping in the mind the conditions of the third-world countries and its citizens. It has been made possible through the lens technology called SlideLens. It has pair of lenses that work complimentarily to adjust vision. A wearer can slide one lens over the other from left to right in order to adjust vision and focus. They come in two different types of SlideLens, one is of positive power that works for long-sightedness, the other is of negative power that works for short-sightedness.

The best part comes with its cost-effectiveness as no other eye specialist required. However, the price is indeed a bit heavy for the pocket of a third-world country citizen. It comes at US$39.95, but are worth purchasing as in the long term it will save money. Especially if you are person with an eye-sight that drops more often due to your age or some other reason, you can really avail these Eyejusters’ self-adjustable glasses.
