Lenses for High Hypermetropes

Normally light is focused on the retina at the back of the eye to form a sharp image. Long-sightedness means the eye is too short and the light is focussed beyond the retina. Lenses to correct this are thicker in the middle than at the edges. In a strong prescription, the lenses can be particularly heavy and unsightly. There are various ways to improve the appearance and minimise the weight of the lenses. Choosing a small frame will help minimise the weight. Secondly, consider lenses with a higher “refractive index”. This will also reduce the thickness and weight of the lenses. Choosing lenses with an aspheric design will reduce the thickness further still. Anti-reflection coatings can also improve the appearance and your vision through them.
