PRESCRTIPTION EYE GLASSES

R H Wynne Opticians offers the very best types of varifocal, Bifocal and single vision lenses supplied from the world’s leading lens brands & manufacturers.- ESSILOR, HOYA, NICON AND OTHERS

VARIFOCAL LENSES

Varifocal lenses, also known as progressive lenses (PAL), have a gradual change in strength from the top of the lens to the bottom, with multiple focal points in between. This allows you to see all distances and focus points through just one lens. They are typically used when you have two prescriptions, one for distance and one for reading. There are pros and cons to using varifocal lenses. On the one hand, they are cosmetically appealing, unlike bifocal lenses, as they do not have a visible segment for reading at the bottom of the lens. However, it may take time for some people to adjust to using varifocal lenses.

BIFOCAL LENSES

Bifocal glasses contains a small reading segment in the lower part of the lens and are used when you have prescriptions for both near and far distances. The segment can be of different shapes, round, C, D and executive.

SINGLE VISION LENSES

Single vision lenses will incorporate one prescription only which means one focal point. They are commonly used to for distance, intermediate (arm length) such as for VDU, painting and reading glasses. Single lenses can be made from standard lens, polycarbonate or high-index lenses.
Many of world leading manufacturer of optical lenses has introduced a special type of lenses for high optical quality in order to provide clear vision from the lens centre to the periphery and is very thin and flat at the same time.

PHOTOCHROMIC LENSES

LENS MATERAIL

POLYCARBONATE LENSES

Polycarbonates are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. Polycarbonate more impact resistance than regular plastic lenses

GLASS LENSES

Glass prescription lenses offer the best visual acuity of any eyeglass lens. It’s the most scratch resistant lens material and blocks UV light. However, glass lenses are heavy and are prone to cracking, can shatter with impact. Nowadays they are less common than plastic lenses.

HIGH INDEX LENSES

Plastic Hi-Index -Lenses which have a high refractive index are used in order to reduce the thickness and weight of lenses of stronger prescription.
