Any one who loves their kitchen would want to have big windows to let in the golden rays. It is no surprise that with the increase in human density,buildings that sprung up tend to steal the light which would otherwise shower your kitchen. It is therefore very important that you choose your curtainsin your kitchen wisely.

Hidden health risk in reading glasses: Cheap spectacles can strain the eyes and make you feel dizzy
- Glasses from high street chains have faults which can damage the eyes
- Extreme side effects include double vision, a new study warns
- Consumer group Which? tested 18 models from high street stores
- Expensive £27.50 pair from Boots were no better than a £4 pair

Picking up a pair of reading glasses on the high street probably seems like a far-sighted budget solution.
But while they’re relatively cheap, ready-made glasses may come with a hidden health risk.
They can potentially cause eye strain, dizziness and even double vision, according to an expert study.
Risky: The Which? study found that ready-made glasses can cause eye strain, dizziness and even double vision
Consumer champions at Which? asked an optometrist to assess 18 pairs of ready-made reading glasses bought from high street chains.
The magnification was correct across all the samples. But he noted other faults in eight pairs of glasses, including some from Boots and Superdrug.
And the faults were not confined to the cheapest. The most expensive pair cost £27.50 from Boots – but they were no better than a £4 pair from a chain called Tiger.
The worst example was sold under the Clarifeye brand at Poundstretcher for £2.99.
Which? said: ‘These had three main faults. The lenses were not centred correctly, they were distorted and loose in the frame.’
A Foster Grant pair which cost £18.50 at Superdrug were also incorrectly centred, as were a £27.50 pair described as Style H by Boots.

A spokesman for Which? said: ‘Buying ready-made reading glasses may be easy on your wallet, but our snapshot investigation shows that some could put your eyes under too much strain.
‘The faults we found could cause symptoms in the wearer, from headaches to eye strain, slight dizziness and even double vision.’
The consumer group said the research findings make it difficult to recommend a particular brand or retailer.
Rather, it said buyers should look out for glasses protected by packaging which show no evidence of dents or scratches.
It said: ‘Make sure the frame is marked with industry standard markings such as CE. Ensure the frame fits comfortably and try them out. You should be able to read easily for two minutes.
‘If you buy them from an optician, ask for the lenses’ power and centre positions to be checked.’
Which? also advised buying pairs which have a spring hinge and to go for plastic frames rather than cheap and thin metal, which can break.
